In-Flight Web Access Coming Soon? 172

tewl wrote to us with news that in-flight Internet and e-mail may soon be available on commercial airline flights, but that U.S. airlines are still wary of it. It sounds pretty interesting, but it also sounds like the earliest it's going to roll out is next year. Honestly, I'd like them to work on power adaptors first, but, hey.

In-flight Web Access Coming Soon?

  • I expect them to have screens at every seat. . .

    But you'll have to rent the keyboard and mouse, just like a movie headset (complete with airline-proprietary connector. . .). And good luck getting ANYTHING done in cattle, er, coach class. . .there just isn't room, even if they had little chiclet keyboards and touchpad mice.

    A couple of hundred pax on a jetliner, figure at most half will actually go online, and most will accept modem speeds. So figure an on-board proxy server feeding 1-2 DirectPC-type satellite links, with a satellite uplink as well. . .

    And three guesses as to the likely browser and OS of the inflight system. Especially since Boeing is the OTHER big outfit in the Seattle area. . .

  • Hi, Currently Delta, United, SAS, SwissAir and many more quality airlines offer EMPOWER in the seat (business class). I understood that Delta would be the first in the world with this. You would get some laptop-adapter for it, so no crappy phone lines. The funny thing is also that lounges and gates would also be equipped with similar technologies. So al together this is not too bad. The only thing that is left to worry is the price of it all.... Cheers, Brenno.
  • I agree completely with you in terms of the comfort. Especially because my company never decides to send me on trips at the last second and then still looks for rock bottom prices. The record all time worst itinerary: 20 hours in the air travel system to get from Manchester to Sacramento, when I could have flown direct Boston to San Francisco.

    And, I travel a lot.

    But -- I don't think that trying to squeeze a laptop into the mix really helps. I'd rather have a book, or just to sit and daydream.

    Frankly, in terms of innovations, I'd take an airline that gave me two inches more width or depth over Internet access any day.

  • There shouldn't be a problem with cell-phone access from the trains, esp. with the digital phones, you get more problems from the fact the train is a metal cage and blocking signal.

    Do you realise just how many of the cell-phone companies actually use Amtrak property to house their antennas, so most of the time your phone is close to an antenna.

    And on the East Coast all of the main fiber lines run along the railroad, simplifies all the real estate issues, just one entity to deal with.

    What would be nice would be to convince them to run 802.11 along the corridor.

  • Well, the previous poster that described what's actually being planned pretty much turned me off it. Sounds more like eye candy to keep passengers happy, with enough live content to give the corporate types something to play with.

    What's wrong with having one big broadband wireless connection to the ground, with a router and DHCP server on the plane feeding a gigabit LAN? Maybe the connection speed to the ground would suffer, but enough people use cable and DSL now that they're used to sharing the pipe, and there are ways to make sure the bandwidth is shared fairly.

    If the DHCP server does DNS as well, you could map an onboard web server that has live updated flight info, position maps, interesting things to see out the window (does anyone look out the window anymore?) and even online flight safety pages. *That* would work. The proposal I saw just now is more a way to get advertisements onto our screens than anything else ..

  • Damn right CRTs are a safety issue. Being 6'5", those things can be deadly.
  • Web: As noted, there's cached web content. However, it's not all just static crap. Partnerships with various places and search engines will allow searches, online orders, etc, in flight.

    I think you're going to have serious limitations on web connectivity with Tenzing's scheme. A Major Application of in-flight web access is travel scheduling, and there is no way you will be able to upload the entire search space of travel information/connections etc. A small subset of the search space, no doubt culled from your content-providers, will not be useful. When people make changes to their travel itinerary, they need access to *all* the possible permutations of schedules/airlines/hotels/fares etc., unless I am missing something I just don't see how you will be able to povide that kind of functionality. And if you are offerring web access without a real-time travel-planning capability, then you'll lose a major chunk of the functionality and subsequent revenue.

    If I am sitting in flight and I suddenly need to change my itinerary, I am not gonna be happy if the only travel website I can reach is MSN Expedia. And give me a break - will these content-providers have any reason to give me the full selection of discount fares that I can select from? More likely I will get less choice and higher prices than a land-based travel planner. On a plane, you're the ultimate Captive Audience.

  • If you can relax in a coach class seat, then you're a lot smaller than I am (and I consider myself to be a pretty "average"-sized guy). Sleep on a plane has never been really possible for me under normal circumstances.

    When I'm on a long plane flight, I'm DESPERATE to find something else to do besides think about how cramped I am. Books, my laptop, cheesy portable arcade games - if I don't have them, then I really AM wiped out when I reach my destination!
  • Actually, I got the info from a friend who was involved with the study (they work at the NTSB), when I asked about the safety record of the 747 because of what happened with Flight800.
  • Good point about the split bus, those gensets would fight terribly. Constant Speed Drive? Revolting! Unless it's hydrodynamic, there are too many things to break.

    A direct connection to the turbine would be horribly complex. A pnematic or hydrolic connection is simpler...

    But IIRC the APU on the B737 is a tiny thing, not like the engine on the B727. How can it produce enough compressed air to start the big boys? You'd have to run a 2" line clear to the expanders, and use it as a storage vessel.

    Also whilst the B727 has everything in one place (at the back) a B737 has an engine on each wing and the APU in the tail.

  • Damn, that would be nice. But will it work at 150 mph? I would think an 802.11 wireless LAN inside the train connected to a high-speed wireless pipe (type is left to the reader: 802.11 again? something else?) that gets picked up by a series of base stations along the route would be brilliant.

    Someone go do this. You'll make a ton of money.

  • But -- I don't think that trying to squeeze a laptop into the mix really helps. I'd rather have a book, or just to sit and daydream.

    Just depends on what you like to do for fun - I'm pretty consistent about zoning out when I'm in front of a computer screen (much to the irritation of my family). Time goes pretty fast for me when I'm doing it though.

    What I _really_ fantasize about is having a wearable virtual reality setup - plane? I'm on a plane? oh yeah, I forgot :)

  • I already have to deal with the inane questions from the guy sitting next to me. All I need is for the whole freaking plane to try and have a conversation with me.
  • I was right there with you ... until you mentioned the lack-of-crowds.

    I too am about 6'4, and I take Amtrak to Virginia all the time to visit my girlfriend.

    And the seats are _truly_ lovely (especially compared to airline travel!) and it's reasonably quick.

    But the Philly-to-DC-and-parts-south run is usually ALWAYS packed! On a typical day, it's SRO until at LEAST Wilmington, if not BWI!

    But that's a quibble. I concur otherwhise most wholeheartedly - Amtrak is a pretty nice way to travel.

  • No, I'm pretty sure that power isn't a big issue. If it were, they would replace the CRTs with LCDs for showing the in-flight entertainment (true, newer planes use LCDs, but not because of the power drain).

    Anyway, it wouldn't be a safety issue--you can bet that it would be set up so that if power runs low, non-essential systems go first. You might not like having your laptop considered non-essential, but that's life.
  • The DC3 (operator US Airways) I flew to Atlanta on in August allowed "Data/Email calls" for $1.99/min. It was too expensive to play with, but there.

  • But then I'll try to post, and then...

    Well, then I'll ask the stewardess for a stiff drink. :)

  • "On-board e-mail and Internet capability is inevitable for the airline industry," said Kent Craver, manager of on-board product marketing for Continental Airlines Inc.. "We're just not sure how and when."

    It sounds like someone in management said "Make it happen!" This means the implementation will be haphazardly thrown together. We already have problems with Laptops and portable radios interfering with the radio navigation used by airplanes. I can imagine the new problems this may cause.

    I can't wait to see the headlines:

    Hackers Take Control of Airplane While in Flight

  • When I fly (which granted, is not very often), I like being able to get away from technology. I don't want to have Mr. Stock Trader on my left and Mr. IRC Junkie on my right while I'm trying to get some sleep on an aeroplane. National Public Radio [npr.org] had a commentary about this a month ago or so, where this woman didn't like this and cell phone usage becoming possible on the planes, because of the noise, stupid people who won't get off the fscking phone when they think that they can make a buck off of what they're doing, and the idiot on the aisle seat who won't put the @#%^ laptop away and tray table up so she could get up to get to the lavoratory. I LIKE getting away from electronics from time to time.

  • Is it really necessary that my neighborly seat neighbor is hot synching his palm while spilling his bloody mary on my white jeans ?

    Is it really necessary to wear white jeans?

  • Notice how all those listed are for airlines and not individuals?

  • You have the schematic for a B737? Where the hell did you get those?!

    From United Airlines' B737 ATOP course. They are more of a block diagram than a full schematic. If you've ever seen a B737 taken apart for a "D" check you'll realise that the full schematic would be rather large (especially for the electrical system. There are large bundles of cables everywhere).

    I'm glad I'm the one who doesn't have to hunt down a break or short in any of those miles of wiring!

  • I think the laptop power converters change 115VAC to 15VDC with a very high, 0.99 power factor.
  • A good intranet would enable empowerment of passengers to focus that air rage. If I could email or IM everyone on board and we could all agree to demand more pretzels or on-time service...

    More seriously, I would be less enraged (as a frequent flier) if I could do productive things ... or just click on pretty widgets to kill time.

  • What if there was never a crash with a privately owned 747? Then you wouldn't see any individuals right?

    I did notice that it said: "Listing of all accidents in which the aircraft involved was damaged beyond repair:"

    I work in this industry and have a bit of an idea of how many privately owned _large_ aircraft there are. Let's say that the sky isn't crowded with privately owned 747's.

    I can see it now, you're sitting in your seat, surfing over to cnn.com, and suddenly you see a web page announcing that the airport you're landing at is having massive electrical problems resulting in planes crashing left and right... ;-)
  • Or terrorists will take advantage of this and make their demands via IRC.

  • Do you really want to hear "You've got mail!" coming from the cockpit when you're about to land?

  • Why not make it two-way and use airplanes as weather probes?

    Great... just what we need... an SNMP managable 747 (talk about a need for "Collision Detection" on your network!)

  • For the defendant, it sure helps obfuscate that pesky jurisdiction problem!
    "The first 4 characters of the command began while the plane was over TN, but the line was completed over Arkansas..."

    Oh... so what you're saying is, it should be tried in a Federal Court since the act was perpetrated while crossing state boundries? :)

    Currently it costs like $2/minute and $5 for the first minute on the in flight phones, and that's at pretty crappy quality, it can barely sustain a 14.4 modem over it. What's the price going to be for a full 64k (atleast 64k) digital link? This is probably only going to target business travellers who are on expense accounts, not your average recreational geek who pays out of his pocket for this sort of thing.
  • by Alioth ( 221270 ) <no@spam> on Thursday September 14, 2000 @01:01PM (#778925) Journal
    OK, let's take the good 'ol Boeing 737-200 or -300.

    The plane has three identical generators - two driven off the main engines, and one driven by a small turbine in the tail (the APU).

    The generators are connected to the engines by a CSD (Constant speed drive) that...well, runs the gennies at a constant speed. The CSD is basically just a mechanical transmission. They generate 120 volts at 400Hz. (Incidentally, that's what that 'whine' is on the audio channels that you can hear - it's the 400Hz bleeding over). DC power for the stuff that runs on DC is 28vdc. It is either provided by the battery, or by the T/R (transformer/rectifier) units from the 120VAC supply.

    Normally, in flight, the APU gets shut down, and power is provided by the engine-driven generators. This energy isn't free of course - if everyone turned their laptops on, the Captain would have to push the thrust levers a little bit more forward. I don't remember what the ratings of the generators are (but if you're really interested, email, and I'll look it up).

    The generators cannot supply the same bus at the same time (there's a left and right bus) because if they are out of phase, all hell breaks loose. (The B727, so I am told, can run more than one generator on a single bus, but the B727 has a flight engineer to make sure everything is in phase)

    Other aircraft services, such as pressurization and airconditioning are NOT electrical (although they are controlled electrically!). The air you breathe in a plane comes out of the engines off some of the high-pressure compressor stages (the compressor is *before* the combustion chambers). This extremely hot air goes through the PACKs (pressurization and airconditioning kit) so that it reaches you at the right temperature. Incidentally this is why you sometimes get smoke in the cabin when that engine all the way out there on the wing croaks.

    Have you ever wondered why the lights flicker just after engine start? Well, on the B737 at least, Boeing employs "break before make" switches when the two power buses are switched from the APU's generator to the engine driven generators, hence there's a brief power outage when one of the pilots reaches up to the overhead panel and throws the switch.

    Also...the engines on the B737 are not started by electricity! They are started by compressed air. To get the engines going, first you have to crank up the APU and use its compressor bleed air to start the engines. Smaller jets have electrically started engines though (bizjets like Lears, Citations etc.)

  • Its even better when rental cars have them... and then have a marker that says they are not to be used for cigarettes :)

  • I took and American Airlines flight recently that had power adaptors... they were car lighter style... but that was cool enough for my laptop accessory bag. :)

    As for in flight web-access... I'm sure it will be as reasonably priced as those in-flight phones... right? I'm sure they'll knock the price down to $1 or $2 a minute - or something equally reasonable... :P
  • Hi! Actually, Swissair already offers "plug-into-the-seat" power supplies on all their long-haul fligts (in business and first class). All you need is the standard converter/adaptor (which you can buy on-board or in most travel shops)...
  • I'm sure there are plenty of more important improvements to be made to airline service.

  • Give it read-only access to the navigational computer (assuming they're adding this to new/retrofitted planes and not trying to bolt them to thirty year old DC10s) and some motors.

    After all, before those fixed Hughes mini-dishes sprouted up everywhere, satellite dishes were BIG, and you had to point them all over the sky to get different channels.

    If the plane makes a really sudden change in heading or something you might lose the signal, but presumably that doesn't happen unless you're about to crash - the plane, that is. ;)
  • Check out American Airlines flights.

    I'm not sure if its standard on all of them yet, but the majority of the flights I've been on lately (on the NYC Chicago run) have cigaret adapter plugs located between each pair of seats.
    (ie one outlet on the two seater side of the plane and two on the three seater side of the aisle).

    While not an ideal situation (a lot of us still have only the regular AC adapters, and if everyone in your row has a laptop it gets interesting), but still much better for the business traveller who knows he's going to be flying around a lot.


  • It's actually just electronic devices that aren't FAA approved. Meaning, anything the airline owns is OK, and anything they don't isn't.

    Part of why they don't want you using things is that an airborn cell phone has a stronger signal than one on the ground, and can talk over (and disconnect) other connections. Also, since you're hopping from one cell to the next so quickly, you're leaving a wake of disconnections, and frequently, no billing. (You apparently move through a cell faster than it can recognize you, and bill you.) Some of the in-air phones are apparently linked to a bigger cell-phone antenna that connects to well-placed, special cell phone towers.

    I'm not aware of a cell phone, or other electronic device, causing problems on a modern airliner (it'd surprise me with the level of sophistication up there in the cockpit), but I am aware of one chap who wouldn't hang up his cell phone, and was charged with an offense.
  • they don't let you into first class with white jeans
  • right... and thats because cell phones and pagers work at a frequency that would disrupt the coms the pilot uses. maybe its just me, but if the pilot, the guy who is flying me thousands of feet in the air, tells me not to use my cell phone, I'm not going to use my cell phone. as for having to use the 11 dollar a minute phone, that's because those phones are designed not to interfere with the pilots coms. If you don't like what they charge you, don't use the phones. If you really had something important to tell someone, you probably would have done so before you got on the flight on one of those nifty 35 cent payphones. If you forgot... well, that's kinda your own fault bud.
  • Gave into temptation and responded to this post. I really shouldn't respond to this particular post.

    Anyway, Amtrak is, yes, highly lovely. My work stuffs me on the train to Penn Station in New York every Monday, and back home again to DC every Friday, for the next 3 weeks at least.

    Seats are comfy enough that I can sleep on the way up, which is fantastic. I can actually reach the foot rests on the Metroliner cars (I'm 5-0 barefoot)
    And, best of all, there are 120v plugs at every seat. Which means, as long as your seatmate isn't already on his or her laptop, WOO! Three hours of Alpha Centauri, Nethack, Roller Coaster Tycoon, or whatever other mindless game you want to waste your time on for the duration of the trip.
    The dining cars, btw, have Trainphones, which I believe you could plug a laptop into if you wanted. Expensive but, hey, its a connection, right? A cell modem would work just as well, or a modem-to-cell adapter.

    Either way, trains are SO much nicer than planes. Room to strech out, better food, and no need for batteries. Oh, and no stupid "Turn the laptop/phone/whatever off!" rule!


  • Back in '95, I rode a flight on Southwest Airlines. They had a small LCD screen on the back of every seat. I don't remember it's full capabilities, but you could do stuff like check stock quotes, and read news stories (about like dailynews.yahoo.com [yahoo.com]).

    Of course, it wasn't the internet; you couldn't browse to a random URL, and (IIRC) there was no email facility.

    Tenzing [...] is offering a "cached" or prepackaged Internet stored in an on-board server computer
    Gah. This idea is hopelessly broken. How are you going to cache Google [google.com]? The most interesting parts of the web (like every search engine) generate content on-demand...

  • on a flight back from Hawaii in March (the wife was attending a conference, so I tagged along for cheap) one chap got booted from first class back into sardine-class with us. The flight was about 30 people overbooked.

    After loudly announcing that his wife was up there in first class, repeatedly (and why, we don't know), he settled down into his seat, got out his Mac powerbook, and started watching a porn DVD.

    I can hear it now, "Stewardess, can you make that man surf with both hands?"
  • wireless networking on jumbo jets?

    you know all those near misses you hear about in the news ("TWO PLANES CAME WITHIN 150 FEET OF EACH OTHER TODAY...").

    hmmm....

    what is the range on 802.11 again?

  • I know there's a FAA restriction that limits use of electronic devices under 10,000 feet, after which point anything is allowed, with the exception of form of two way communication.
  • I wonder how the LAN would be set up...

    It would be very cool if a Quake 3 CTF match could be played between First Class and Coach passengers... :)

  • There's a live demo of in-flight access going on right now (or least, it was going on an hour ago) by Globalstar here [199.106.114.4]. It's a sort of lame but mildly amusing in-flight webcam of 2 engineers from G* and a local news crew flying around Los Angeles, talking to people on the phone over the Internet, using AOL IM, getting email, etc.
  • I hope this technology doesn't bleed into the cockpit. Who wants their pilot surfing the web?
  • Amtrak is great on certain (fast) corridors: NE Corridor, Chicago-Milwaukee, SF-Sacramento. The new Acela [acela.com] service from DC to Boston is quite nice, though they're not yet using the new cars.

    Unfortunately, once you get off the modernized tracks, you're sharing older tracks with freight trains and may find yourself delayed significantly. They're getting much better, but for business travel it really depends.

    In a move that the airlines (and the computer biz!) should emulate, they recently introduced an unconditional money-back guarantee. [amtrak.com] Pretty damn good.

    As for cellphones on trains, this doesn't work so well on electric routes (notably the NE Corridor, DC-Boston). I think there's too much interference. Anyone working on always-on net access from trains (which would be so, so nice!) would need to solve this problem before it would work well.

  • If you think that's bad, on a recent AA flight (IIRC, might have been Continental) to the UK, I looked up the charges to use their phone outside of US airspace.

    It was $15 to be connected, then $10/minute.

    That is $615 per hour. For that price, I could:

    - pay for a Bell 206 helicopter AND pilot for an hour.
    - pay the direct costs of a one hour flight in a Lear 35 bizjet.
    - fly a Beechcraft Bonanza for six hours.
    - fly our Cessna 140 for 30 hours (which is plenty of time to get across the Atlantic and back if you don't mind doing it single-engine at 85 knots)

  • I've never quite understood why the people who are generally decent and well off enough to fly, go nuts and embark on a drunken binge when they board a plane.

    Its cause you get drunk faster at lower air pressures, and the air pressure in an airplane at 30,000 ft, is about like being at ~8,000 feet on the ground. So basically you drink what you are used to and get more kick...
  • I have been testing Real tournament on the tenzing system and it works great.

  • I can see some great uses for this.
    • I can check on the price I would have paid had I used a different airline, and try to make the stewardesses feel guilty about it.
    • Start screaming "We're all gonna die, we're all gonna die" and later explain that it was a team Quake game.
    • Check the airline's website and find out when we will really land.
    • For the ultimate overclocking/cooling experience, have the stewardess put my box out on the wing with the case open.



    My mom is not a Karma whore!
  • Hey, this sounds like fun!

    Fly across the country and try to hack your way into the airplane's Internet server. It would be a lot more interesting than watching the lame movie.

    I can just see it, "you have been owned, bi-atch", popping up on everyone's web browser.

  • Talk about downing a server...
  • Singapore Airlines has had power adapters available on business class and first class seats for over a year. I think Delta does also. They require that you purchase a special adapter (~$79.95), but not worrying about the batteries in the laptop while cruising over the pond is well worth it.

    Boeing has been working on this for a couple of months. They are mainly hoping that an internet-ready BBJ will persuade more people to look that way instead of a GulfStream, etc...
  • I've always wondered why the doppler effect doesn't seem to effect phones on the aircraft (even though quality does suck, which is probably the doppler effect kicking in). So if the doppler is making the quality of an airline phone terrible, how will this effect data? If it's not doppler making the phones poor quality, what is being done to combat this effect? Any ideas/answers, E-Mail me [mailto].
  • I'm not aware of a cell phone, or other electronic device, causing problems on a modern airliner (it'd surprise me with the level of sophistication up there in the cockpit), but I am aware of one chap who wouldn't hang up his cell phone, and was charged with an offense.

    If you look at the FAA's anonymous safety problem report database, there are quite a few reports of weird avionics problems that appear to have been caused by passenger electronic devices. The scary thing is the large number of passengers who refuse to turn off their devices after repeated requests from the crew, and who lie about having a device turned on. They should be asked to leave the plane, at cruising altitude.

  • In the print version of IEEE Spectrum this month (not sure if it is on-line), they had an article on improvements in aviation weather forecasting.

    One of the things that they want to do is transmit real-time weather data to aircraft in flight. The problem is that it takes a lot more bandwidth then they have currently available to do this, so they are going to start putting in high-speed communications links on aircraft (via satellite, etc.)

    The problem with this is that the increased bandwidth costs big $, so they are thinking of offsetting the cost to the airlines by offering some of the spare bandwidth to passengers for entertainment services including internet access.

    I agree that free is the right choice. The vendors are of course approaching the PHBs that run the airlines and pitching them on incremental revenue, so there needs to be a lobbying effort by the users in favor of free and useful internet access.

    It's also very important that the internet access be real internet access, not some "air traveler portal" piece of shit. Local caching may be fine for Yahoo et al. (perhaps one could install a mini Akamai server on the plane?) but if this is anything like those touch-screen terminals in the airports now, it's close to useless. We need:

    - ethernet ports to plug into, with DHCP;

    - full access to the net (slow speed is ok);

    - non http/pop3 applications (telnet, ping, ipsec); and

    - no mandatory home page or ads!

    A fast intranet would be nice too, so people can AIM and/or Quake with each other.

    If it's designed this way, it will be fabulous and make me switch airlines. I'd even pay $5/flight for it. But I'm not holding my breath.

  • As pointed out in this thread elsewhere, some devices can be more powerful than the ground-to-cockpit communication, and can lead to potental problems. Commonly, in the states, it's also asked that you turn them off during takeoff and landing -- this is due to (but not only because of) the fact that you the passanger need to be at maximum attentiveness during these periods where the most likely form of an accident will occur. Having your head in your laptop computer, or blabbing on the celphone is going to divert your attention from any important life-saving messages the pilot and crew may be shouting.

    I would suspect that with this network in place, it will still be the same thing - you can't use the laptop to connect to the 'net until you've reached cruising altitude.

  • I think the company "www.avrotec.com" is partnered with Microsoft and NASA to create the next generation "Highway In The Sky" ("HITS") aircraft instruments.

    Supposedly, they will make it "as easy to fly as it is to drive a car". You just joystick your way through a tunnel/mesh to land and take off, and everything else is autopilot.

    They run windows apps, too. Shame that NASA is using our tax dollars, partnered with MS, to create all this stuff, in what is essentially a closed consortium.

    I think I'd be more comfortable if it was open sourced!

    Does anyone know any more details on this project?
  • All three generators on the B737-200 or -300 has a load limit of 125 amps. Nominally, that's 15kW (125 amps * 120 volts) per generator, and under normal operations, two are in use.

    I can't find the information on how much the bleed air off the APU gives you - but there's a limitation on usage of 10,000 feet if you're taking bleed air and electrical power off the APU, or 17,000' for just bleed air, so it probably isn't too much. The schematic of the pneumatic system just shows lines coming off the APU and going to the main engines for starting (plus a few valves along the way). The main engines have pneumatic starters that spin up the N2 stage. Additionally, the APU can only operate one PACK at at time. The APU is additionally not powerful enough to provide wing anti-icing (another use of bleed air). Main engine bleed air is taken from the 8th and 13th stages of the N2 compressor (-200 series, P&W JT8D engines - the long, skinny ones), and you can use the bleed air off one engine to start the other.

    The constant speed drives that run the generators off the engines are hydromechanical units - internal oil used as an operating fluid and for cooling. The APU doesn't have a CSD since the turbine is designed to operate at a constant speed.

  • Good God! Do you have any idea of the power that runs through an aircraft? Do you KNOW how many watts a single 100,000hp engine produces (of which the 777 has two of)? Thats roughly 74.5Mw per engine. Aircraft are designed to run on a single engine at take-off (the most aircraft-stressful portion of flight). That is a LOT of extra wattage.

    Power was never a consideration or drawback - the weight of the extra wiring is (and always will be). That is one of the major reason US Airlines are hesitating to sign up for the inflight-net service - the extra weight of the equipment needed. In aircraft, weight == money. The more weight the aircraft has, the less it can carry. The less it can carry, the less they make off of it.
  • Yes, these are useful. USAir also has these. UAL only has them in first class on 777 and renovated aircraft.

    Despite their general availability for some years, UAL chose not to put them in coach. Typical behavior of the world's largest, and crappiest, airline. So I have limited expectations that web access will be any good, at least on UAL.

  • The reason for disallowing use of certain electronic devices on airplanes is that there were a series of unexplained mishaps around 10 years ago. In-flight instrument failure that investigators to this day haven't figured out the reasons why it happened.

    So the FAA said "Gee, it COULD have been portable electronic devices that are to blame" and imposed the ban. No laboratory test has ever shown conclusively that portable consumer electonic devices are even CAPABLE of interfering with aircraft systems. Never. It's a bogus ban based on anecdotal evidence.

    It has bothered me for a long time that they continue to perpetuate this falsehood. At the same time I am grateful that I don't have to sit near people who are constantly on their cell phones. That would drive me crazy. I hope they keep the ban on cell phones for purely aesthetic reasons even after they come to their senses about the non-existant danger they always tell you about.

    Teehee. We've made some press announcements so I don't think I'm breaking NDA by posting this stuff.

    Anyway, I work at Tenzing, and here's some info to clear up some of the confusion. You may think some of Tenzing's ideas suck, but hey.

    Email: You'll be able to use your current email account, you won't need a special tenzing account. There's some software that basically "dials up" to the onboard server; your laptop thinks it's connected to your ISP. It's pretty transparent, except you gotta use our SpecialNiftySoftware to start the whole process. Then the server just acts as a proxy between you and your ISPs actual mail servers. Mail gets collected, and every x minutes (set by the airline) all the mail is bundled, sent to the ground, and new mail for you gets sent up to the plane. So there is a delay.

    Web: As noted, there's cached web content. However, it's not all just static crap. Partnerships with various places and search engines will allow searches, online orders, etc, in flight. Selected stuff will be updated during the flight, like stock quotes and maybe weather and whatever else our marketing dorks decide is necessary, but most updates will happen between flight legs.

    Actual connectivity: None, yet. Some companies are working on actual broadband access during flights, but it's still experimental. We hope to get partnerships with these folx later. :)

    Electronic device usage: Well, standard airline rules apply. The connection is thru the plane's phone lines to the seats, so there's no special new concerns. We've asked about using wireless, but the gov doesn't like that idea at the moment.

    Quake games: Probably possible, but remember that, at least at first, you're limited to phone dialup speeds (since you connect thru the modem). Whether the games are doable or not depends on how the engineers setup the onboard boxes.

    A piece of trivia: The servers are all running some OS that happens to be pretty popular around here. Muahah.

  • You have the schematic for a B737? Where the hell did you get those?!

  • Yet another reason for airlines to raise prices.

  • I think you are full of shit. Here's a list of all 747's taken out of service, and (for most) the reason why:
    http://aviation-safety.net/datab ase/type/104.shtml [aviation-safety.net]

    You tell me which the other two are.
  • If your main purpose is to attract new customers, but you also want to cover some of your costs, $5/flight x 50 people x 4 flights per day would probably make economic sense. Besides, would you pay any more than $5/flight for internet access?
  • I don't think aircraft in-flight have significant extra available electric generator power

    Yes, actually they do. To give you an idea of In-Flight Entertainment (IFE) Systems out there, their power requirements range roughly from 7.500 to 35.000 Watts for a 300 seat installation (with individual displays).

    I don't want to go into the details of IFE systems, because I am biased (I work for the one and only, tha best! ;)) but it's pretty DAMN crazy.

    I do have to say that it's painful to finally have an article about our industry on /. right before the annual show (WAEA). Don't you guys understand we (the engineers) are all working our balls off to get the equipment ready for the show!

    Gotta run (some wires tween aircraft seats :)

  • I used to fly back and forth between Newark and Boston on a regular basis. I flew so much I would end up with FF miles, and upgrade coupons. It was always a hoot to be in First Class. 7 guys in business suits, reading the WSJ, and me, tshirt, jeans, and a laptop, happily coding...
  • The prices I have seen quoted for this service are ridiculous, especially given the testimony of one employee of the provider that this is not real, live access - it's batched email and cached/canned web content.

    Even if I am on an expense account $12/hr for 'internet access' is ridiculous. I can batch up my emails myself and send them when I get on the ground thank you very much.

    The same thing applies to in room hotel broadband. Most of these services are priced at something like $10-$15/day. What?! Most business travellers might connect for thirty minutes each night to check email. For this a modem is quite enough, and virtually free. Its fine for web surfing too. I just don't get that much more out of a broadband pipe to justify that kind of cost.

    These bozos need to learn something about pricing. When you offer a service and charge a hell of a lot more than the competing service, it had better offer a lot more, either in the way of convenience or services.

    On a plane the competing service is waiting to get to a land line on the ground. Most people will gladly do this, accept perhaps on extremely long flights. Add to that the complexity of setting up the service and the software and the in flight internet access just does not seem to be a competitive service - it is way over priced and only marginally more convenient than the free options.

    Also on the plane, Internet access is competing with the inflight movie and reading materials - which are virtually free to the traveller. This is about the only reason I might browse the internet on a long flight, for entertainment purposes. I don't know that reading some canned day old wall street journal web site on my laptop is better than reading the real thing I bought for 75 cents in the terminal.

  • They're all going to be at the WAEA show in Anaheim, near Los Angeles, next Monday to Friday. It does cost $135 per ticket for the public though, but maybe you can share tickets :-)

    They're the people who are actually going to be implementing on-flight web access, on-demand video, etc.

    I would mention the in-flight entertainment company I'm working for during the summer here, but we don't want to be slashdotted! But we've got satellite linkup working for Net access in a development model, with USB connectors for laptops etc. (software for that not written yet), along with cool proper on-demand video - pause, fast forward, rewind all work - much better than what I've experienced on Virgin Atlantic recently!

  • that was only 6' square?

    Airline internet access is a logical corrolary overall erosion of time to relax. I'ts inevitable that it will happen, and it will do good for some people some of the time, but most of the time it means you can arrive at your destination completely wiped out.
  • TWA Flight 800 was a 747 that was purchased from an oil sheik in the mid-east. It was one of three aircraft (the other two which also exploded in mid-flight) that the sheik had specially modified. IIRC, those are the ONLY 747s in the history of the aircraft that were brought down by electrical failure.

    Not ALL of the power is used to provide thrust (although you are correct when you say most is). As was pointed out before, there are a few airlines that already have jacks at every seat. My point was that it was NOT limited by power (as the original poster suspected), but by weight and money.
  • The 'phones currently on most planes are low-level satellite up-links (normally the Racal MCS-6000 nowadays, which has an uplink bandwidth of about 64K, IIRC) which are then split into up to 8 lines (radio for cockpit and 7 speech lines of about 8Kbps - if not all lines are in use, they have 3 lines of 17.8K, or somesuch, and an extra one. This, as you can guess, is not great, but when it came out, some years (5?) ago, it was pretty nifty.

    Now, however, broadband satellite uplinks are on the way - with a 128K + shared data pipe connection for passengers, and dynamically portioned speech bandwidth of about the same, featuring useful items like a data uplink channel that relays data about the plane's systems to an external system (redundancy for the black box system, and useful as an aide in diagnosing problems from the ground as well as in the air). These should be avaliable RSN, and will be fitted to a plane near you soon. Hopefully :-).

    There could be a lot of privacy issues here.

    The domain would probably identify you as a passenger of a given airline.

    It could easily be misconfigured so that cookies survive between different legs of the same flight, so that someone on a latter leg would already be signed in to whatever servers the previous passenger had been visiting.

    And of course, just like with laptops, anyone sitting nearby can see what you're doing. So if you like to visit porn sites, you'll run a risk of offending other passengers. Air rage? Yet another cause. Oh wait, they'll probably use some censorware to solve that problem and create a bunch of new ones.

    Anyway, there are a bunch of issues for the airlines to deal with. Personally, I would prefer if they just provided a power outlet and an ethernet port (or run wireless networking--wouldn't the FAA love that!).

    Now the airline that makes it free instead of $$$/minute will see a huge boost in ticket sales.

    I don't think aircraft in-flight have significant extra available electric generator power for more than a few first-class seats. They do suck back ~30W each. Or to get it, they would have to turn off reading/cabin lights.

    Hopefully, it wouldn't come down to: "Please unplug your laptops. The captain has just lost all the flight instruments!"

  • If I were CEO of an airline, I would make it free. It may cost a bit to roll out, but it would be a key factor in getting travelers to choose that airline.

    For bandwidth, this is an ideal situation for sattelite Internet. Just adapt one of those small dishes for use in an airplane, and you'll have decent download bandwidth. You'll have to be a little more creative for the upstream side, but people will usually tollerate that being relatively slow.

    Huge Costs
    Many modern aircraft are equiped with a device called ACARS [arinc.com]. In short it is a VHF communication device between the onboard computerized (mostly) avionics and ground based computers. The VHF band is totally unsuitable for bandwidth over 32k. Airlines use ACARS to track their aircraft and the performance of onboard systems.
    The small monopoly of companies that provide this kind of service charge an arm and a leg for the service. This puts it out of reach for anyone other than big fleet operators.
    I fly a lot. I work for an airline. I really can't remember actually seeing anyone actually using that seat back phone. The airphone provider ate the cost of installation (but not aircraft interest; see below) and gives a percentage back to the airline. I can't imagine there is much revenue from those things. The airlines simply don't get enough money from those phones.
    There is a good reason airlines are against it. There is an old addage: airplanes don't make any money on the ground. Airlines put their newest, best aircraft of premium routes. Taking an aircraft down for a week to install a few ethernet jacks and routers is huge amounts of lost revenue and the non-deferrable cost of whatever financing arangements (read interest) the airline has for that aircraft. Airlines who are still licking their fuel cost wounds aren't interested in opening up the money chests.

    In short, the air to ground technology is still not mature enough to keep the cost low enough to get get enough people to use it.

  • Just a followup. The database is the NASA Aviation Safety Reporting System (ASRS), and the report on passenger electronic devices can be read here [nasa.gov] (PDF file).
  • I can find out (unfiltered by the networks) all about the latest demonstration that I missed because work sent me to the other end of the country at the last possible moment!

    Just have to figure out how to charge the connection fee to the contract without raising a flag...

    Visit DC2600 [dc2600.com]
  • Well the most economical way of doing it (for the airline anyway) would be to have a single digital pipe that everyone shares. 64k would probably be the minimum necessary to feed the entire plane (just for email of course, 300 people surfing the web wouldn't survive on a 64k pipe, but then again probably less than 10% would be using it).
  • For the defendant, it sure helps obfuscate that pesky jurisdiction problem!

  • I just flew to Europe and back, and each of the four planes I took had a facility by which I could hook my laptop up and browse the web, read e-mail, etc.; For now it's obviously expensive and inconvenient (you have to have your own computer), but it does exist.

    As is typical of MSNBC, they're taking old news and presenting it as a dramatic new development. I was surprised not to see exclamation points in this article.

  • Yup, Amtrak is great.

    And they have a common sense ticketing policy with refundable tickets--the person sitting next to you pays the same as you.

    The only problem is that you are on your own for communications. So if you want to be online, you need to use a cell phone connection. (Also, the power flakes out every once in a while, so you can only use it to avoid killing batteries, not to use stuff that doesn't have batteries.)
