back to article iPad no flight risk says Federal Aviation Authority

Being asked to switch off your electronic devices during the takeoff and landing phases of a flight now looks even more anachronistic, after American Airlines announced it has been given permission to let its pilots use iPads in the cockpit “in all phases of flight”. The airline is chuffed that the Federal Aviation …

      Well lately that seems like most flights I've been on recently about five minutes before landing. It seems that tutting isn't enough to get the message across to today's youth.

        Re: Trigger Happy!

        What I don't get is that these people feel that it's their right to use any electronics during the takeoff and landing phase of the flight.

        Just the fact that you have not heard of any accidents does not give you the -right- to have this stuff switched on.

        You might as well start running red lights (because you don't know anyone that got killed while doing that) or running around naked on a plane (because you don't know anyone that got killed while doing that).

        Yes, your justification is that ridiculous.

        Currently the rule is that during takeoff and landing this equipment has to be switched off. What's so difficult to understand about that?

        If you don't like that, make all efforts to have that rule changed. But don't 'flaunt' it.

        But, I guess I'm one of those of a 'dying breed'.

        I'll still rat you out when you sit next to me and have that crap switched on. Of course, only while it's still the rule.

      You're joking, I'm sure, I hope, because mobile phones won't get a signal from the ground at 30-odd thousand feet while doing 500mph anyway. I've left my mobile on by accident in the overhead locker many times before, the plane didn't crash, we didn't lose our way, and when I did retrieve it I didn't have any signal.

        Re: Trigger Happy!

        Unfortunately, the 9/11 recordings demonstrated that cell phones on a plane do work. 30000 feet is only 5 miles, usually no objects besides the aeroplanes hull between you and it.

    The iPad (or other tablet device) given to the pilots will ONLY contain the documentation it's intended to replace?

    Lower fares?

    With 1.2 million flights a year, there is $1 to be divided between all passengers of each flight to lower fares.

    And that's without taking into account buying these iPad to begin with. If they buy one for each pilot, we're talking $5M initial outlay in hardware alone. And then there's the installation of brackets in each aircraft to hold the iPad.

    Expect a fare increase to pay for it all!

          They are not replacing approach plates with the iPad, only the aircraft operating manual. They will still need paper copies of all of the navigational charts needed for IFR flight including approach plates.

    Old News?

    From last years Guardian (Aug 20, 2011)I can quote:

    Pilots on United and Continental Airlines in the US are replacing their heavy paper flight manuals with iPads loaded with a special aviation navigation application created by Colorado-based Jeppesen, while American and Delta are also testing the technology. Alaska Airlines has already shifted over to iPads.

    So the only news seems to be that American Airline switches too now.

      No. The news this time is that the FAA has approved its use, in-cockpit, at all stages of flight.

      Of course, you have to remember that American Airlines is in bankruptcy as well... Don't have a lot of extra money to play with, so they'll HAVE to raise rates to buy the iPads.

    Isn't it about attention?

    I thought the reason they don't want you using electronics is because they want to get your attention easily in case of any problems.

    Personally, I like to take a dead tree format book. I can read right through taxi, take off, landing, everything. Though it's a bit dodgy reading through the safety announcement. If don't pay attention to that, they give you an "I'm going to spit in your in flight meal" look.

    1. Magister

      Re: Isn't it about attention?

      In theory - but the next time that you fly, check out how many people ignore the safety briefing by reading a newspaper or the inflight magazine.

      The was a programme a while back relating to this; they highlighted that in tests, people panicked and completely forgot the briefing that they had received barely 10 minutes before. Several people couldn't work out how to release their seat belts. Most had no idea where the nearest exit was or how they could get to it.

      Flying has become too safe; people are just not prepared for anything going wrong. At the end of last year, I was on a flight that has reached the runway and was just starting to take up position when the pilot aborted due to an hydraulics problem. We had to return to the hangar so that a fitter could check out the pipe. People were actually complaining; they really thought that the pilot should have taken off and waited until the destination to get it fixed!

          Those *very basic* drills that you are shown are intended to actually improve your and your fellow passenger's chance of survival should a mishap occur. Please do not try to second-guess the intentions of those who designed them.

          I sometimes wish the demonstrations and videos were a bit more realistic, showing the pax the sheer violence and confusion of, e.g., an explosive decompression or an aborted take-off. I'm sure it would put quite a few people off from flying, but at least it would get the attention of all the others.

        Remember the Hudson

        I seem to think that evacuation was a 100% success. Everybody did their job and followed the manuals as far as they could.

        Indeed one lesson was that the manuals needed to be updated to get more stuff done in a limited time. Easy if it is in electronic form. More challenging if they have to reprint and re-collate. These things are life and death.

        1. hayseed

          Re: Remember the Hudson

          If I remember, the manual really needed to be updated to close vents earlier - they were left at the end of the checklist, and the plane filled and sank in the water. That the pilot realized that he could land next to a terminal filled with lots of ferries is what led to the success of the evacuation.

      4. Anonymous Coward

        Please spare me

        In theory - but the next time that you fly, check out how many people ignore the safety briefing by reading a newspaper or the inflight magazine.

        So what? It's always the same information, anyone who has flown more than a handful of times already knows how to fasten the seat belt, where the exits are, how to put on your oxygen mask if they drop down, the procedure for opening the emergency exit door, and so on.

        If they were teaching me how to land the damn plane in the event that both pilots died and it was left up to me, then I'll listen intently each and every time because those would be some very complicated instructions, as well as being different on different planes. But the instructions they provide at the start of every flight are simple enough I could have followed them when I was five years old, so please forgive me for not giving it my rapt attention when they are repeated for the umpteenth time!

        Think about this. Which is more likely to cost lives, people flying who have never heard the instructions provided before the flight, or people driving a car who have never been given instructions for what to do in case their car becomes submerged in water, stalls on a deserted road with below zero temperatures, has a flat tire on a freeway in a construction zone with nowhere to pull over, etc? No, this isn't an invitation for some nanny state solution of having a two minute safety presentation in my car every time I turn the ignition before I'm allowed to put it in gear...

        1. ChaosFreak

          Re: Please spare me

          True. The probability of an evacuation is so astronomically low that preparing for it is like waking up every morning and practicing the Heimlich manouver just in case you have to save a choking person that day.

          On the other hand, you're just sitting there not doing anything anyway and repetition does improve retention!

    Tablets are fine and it just goes to prove that passengers have been right all along about interference to inflight electronics.On the other hand if they get damaged or go flat are the airlines going to stop the pilot taking the next flight up or even land early at another destination because he has an equipment failure?..........

      "Given all the technology in a plane's cockpit... why are iPads required to store this documentation? "

      First of all, they're not "required" as such, but nearly all pilots have them anyway, and it's a convenient way to have all the various bits of documentation easily accessible and searchable.

      "They could fit a small screen hooked up to an independently powered Raspberry PI for < $100"

      No they couldn't. That would make your device part of the plane's avionics--do you have any idea what the certification entails in terms of cost, time, effort, and cost [sic]? Why do you think most aeroplane technology is obsolete by modern non-aviation standards?

      "I really don't understand the obsession with using them for *everything*"

      As I wrote elsewhere, they're stupidly popular with airline pilots--like it or not, that means that people will go and write tons of useful applications for them, creating a sort of positive feedback loop.

      "even when it's not suitable (in this case cost more than anything.)"

      In this case, the cost and convenience factors play strongly in their favour. Air navigation data is updated every 28 days. Electronic subscriptions are cheaper (depending on your employer's arrangement with the provider, significantly so), and updating paper charts was no fun at all, especially when you have hundreds or thousands of copies. :( Modern EFBs get updated (semi-)automatically and securely over a network connection.

      I hope this clears it up a bit. I'm no fan of any of the popular tablet platforms on the market, but in this case I can see how this is simply a case of responding to market demand.

    Rubbish Article

    Just FYI, what this article seems to be half-arsedly attempting, and spectacularly failing, to report, is the use of iPad tablet devices as the hardware component of an Electronic Flight Bag (EFB). Some examples of EFBs here:

    Very simply put, an Electronic Flight Bag means you have a portable computer, typically in tablet form factor, which holds relevant documents and applications relating to both the aircraft and the specific sector being flown. A more advanced type of EFB can also be used for tracking progress of the flight (shows a map with a cute aircraft symbol in the middle of it). Initially, these portable computers were custom-made, ruggedised, hardened-electronics jobs. All a bit over the top and expensive.

    For whatever reason, iPads are incredibly popular amongst flight crew: almost everyone has got at least one (yes, some people overdo it and have two or more!). Btw, it is specifically iPads that seem to be in vogue, rather than Android devices--it's just what's "in" within this particular community.

    Airlines, aircraft manufacturers, navigation data providers, and regulators are now catching onto this and essentially making official what has been going on for a couple of years now: people take their devices to work with them and use them to assist in flight planning and execution.

    Many major aircraft manufacturers (incl. Airbus, Boeing, and Gulfstream) now offer iPad-based EFB products. It is up to each individual airline to seek approval for their own use of an EFB solution though. American Airlines have been doing so since at least December 2011, and they have not been the first, so exactly why this is news now, I'm at a bit of a loss to explain.


    Now, as to the specifics in this article:

    "iPad no flight risk says Federal Aviation Authority" --- care to provide a quote, Mr. Sharwood? That seems quite a daft thing for the FAA to say.

    "Being asked to switch off your electronic devices during the takeoff and landing phases of a flight now looks even more anachronistic" --- No it does not. There are human factor reasons why people are asked to put their toys away at the phases of flight where they are most likely to get hurt / massively scared, which have nothing to do with the electronic nature of such devices.

    But aside from that, there is a difference between one or two low-power RF devices here and there, and hundreds of them operating at the same time (possibly at high power all hunting around for a signal, as in the case of mobile phones). To the limited extent of my knowledge, it is not known with certainty whether that causes a problem or not with avionics, but why take the risk? Especially when, as pointed out above, there are other factors that make it advisable to switch them things off and stow them away in any case.

    "A nicer win may come from the fact that if the FAA thinks it is safe for an iPad to operate and emit electromagnetic radiation in the computer-packed confines of a cockpit, surely it becomes harder to justify the order to turn off other machines further back inside the plane."

    This is utter nonsense, Mr. Sharwood.

    "Commercial airline pilot and blogger Patrick Smith has noted that the ban on using electronics is more about preventing them becoming projectiles if a plane hits turbulence."

    Congratulations, so you know how to use Google to discover a well-known blog. At least you got lucky in your search: Mr. Smith does a wonderful job of writing about aviation things in layman's terms. It is a shame that you do not seem to have bothered to contact him and ask him to offer his opinion on the embarrassing drivel you wrote here.

    "The airline is also testing fondlesabs for cabin crew" --- and if they are, in regulatory terms that is an entirely separate matter from what happens at the cockpit.

    So basically, what is this article about? That pilots use iPads? Why yes, most do nowadays--next time you're at the airport café have a look at what the uniformed boys and girls have on their laps (the latter not so much, come to think of it).

    Slightly better informed ...

    During the past 35 years I've been privileged to work with radio interference and electromagnetic compatibility issues of IT, telco, medical and lately, aviation electronics. That may make me slightly better informed on the matter than the average punter.

    Even consumer-grade testing (and what has to be done to pass) is often considered an unnecessary expense, and equipment to be used on aircraft is tested to considerably tighter standards than that sold to the public. "Why are you making us do all these tests? No one else does! You're costing us money!" -- and this, at a firm that made defibrillators. I told him I didn't want to kill folks we were trying to save, and he went away.

    However... Apple bought into doing things right a long time ago. That raises costs, so if you want cheap stuff, you go to the "designed to meet" (not often TESTED) gear from lower cost shops.Good luck.

    ED14, otherwise known in the USA as RTCA/DO-160, is the standard that governs equipment used on aircraft. When the FAA says it approves equipment, it has done so after all the tests are completed,and after it has examined each claim of compliance with a VERY baleful eye. Many baleful eyes.


    That's not the case with run-of-the-mill electronics, though. The FAA doesn't get to look at these test results, so, considering they want something like a _maximum_ of one incident per ten million flights, they just say "Turn it off." That may be too strict; modern electronics uses less power and can produce a lot less radio noise than an old 33 MHz Pentium. They just don't KNOW. The folks who make our kit are largely unwilling to pay what it takes to find out,. And the really uninformed -- some are flight attendants -- think unplugged stereo earphones will interfere with radios in the cockpit.

    Fiction: There we were at ten thousand feet, Messerschmidts to the left of us, MiGs to the right, when the stewardess came up; "Sir, you'll have to turn off your flight simulator now, we're about to land...". So I put away my copy of Aviation Week.
