Time to Review FAA Gadget Policies

Nick Bilton, Lead Technology writer for The New York Times Bits Blog, called the FAA to complain about its gadget policies on flights and got an unexpected reply. Laura J. Brown, deputy assistant administrator for public affairs, said that it might be time to change some of those policies and promised they'd take a “fresh look” at the use of personal electronics on planes. From the article: "Yes, you read that correctly. The F.A.A., which in the past has essentially said, 'No, because I said so,' is going to explore testing e-readers, tablets and certain other gadgets on planes. The last time this testing was done was 2006, long before iPads and most e-readers existed. (The bad, or good, news: The F.A.A. doesn’t yet want to include the 150 million smartphones in this revision.)"

    Obviously, electronic devices can't bring down a plane. Millions of fliers every week "forget" to turn off their devices, and nary a plane goes down. Can common sense finally prevail? Arbitrary rules reduce respect for the necessary ones. For example: No headphones during take-off? Makes perfect sense - take-off is one of the most sensitive times of the flight. If someone needs to yell directions, you need to hear them. Reading a book on your Kindle? Not so much.

      Radio communication with ATC is an analog band just above FM radio, and involves shielded cables running from a shielded radio to one or more antennas located outside the body of the aircraft (which is a Faraday cage at those frequencies unless one of the doors is open, and probably even then).

      Based on that, I'd rate the odds of a cell phone call interfering with an ATC call just south of the odds of getting hit by a meteor while dancing the Macarena. Actually, scratch that. It's more like the odds of dancing the Macarena creating a statistically significant increase in your risk of getting hit by a meteor.

      The problem with using incident reports as a means of determining whether something is safe or not is that correlation is not causation. The fact that the autopilot came back online after four people shut off their laptops does not mean that those laptops caused the failure. It means that the autopilot came back on after those laptops were disabled. In much the same way, it rained in the SF Bay Area after I used the bathroom this morning, so obviously my toilet causes rain.... It's a lot more likely that the autopilot kicked out due to a transient problem in some sensor, a frozen pitot tube that thawed out, a power surge that caused a self-resetting circuit interruptor to temporarily shut off power to a critical piece of equipment, or some other temporary problem that went away on its own.

      However, it is human nature to look for and see patterns even when they don't exist. Thus, after years of being told that electronics can cause planes to misbehave, people immediately assume that somebody's MP3 player is at fault whenever something unexplainable happens on an aircraft. The flight crew tells people to shut down their electronics. After a while, things start working again, so the flight crew then assumes that those electronics caused the problem when the evidence supporting that conclusion is flimsy at best and nonexistent at worst. That doesn't prevent it from being reported as an incident, though.

      If you really want useful data, the flight crew needs to tell those passengers to turn that equipment back on and see if the problem recurs. If it does, then it probably contributed to the problem. If it does not, it probably did not. The problem is that nobody wants to do this because they're too afraid that turning it back on might bring the plane down.

Most accidents occur during takeoff/landing and given that transponders are not required below 10,000 unless within controlled airspace and/or within a Mode C veil, it makes the lower altitudes a fairly dangerous area. Hence why Personal Electronic Devices (PEDs) are prohibited below 10,000 feet and sterile cockpit procedures are enforced any time the aircraft is below 10,000 feet.

      Why then can passengers continue to listen to music and watch TV through the aircraft's on-board entertainment system at altitudes below 10,000 feet?

    One could also compare devices to other existing sources of electronic noise -- the potential discharge of say, a digital wristwatch, a static spark from moving around in the plane, static from wind blowing across aircraft flight surfaces, etc.

The frequency and modulation methods chosen during that era were clearly designed for simplicity and accuracy, not resiliency in the presence of so many RF emitters that weren't even conceived back then.

ILS uses signals from two phased arrays, one on VHF for right/left, and one on UHF for higher/lower. This will bring you to a window in the sky that is about 200' off the ground, 20 feet wide, and 10 feet thick. From there, heading and radar altitude data take over. If you are ever on an airliner, landing at night in foggy weather, I want you to think about this.
