Mobile Phones Might Not Interfere With Planes, But They Sure Can Interfere With Pilots

from the okay,-perhaps-pilots-should-be-barred-from-texting dept

You know how we're not supposed to have our mobile phones on in the air? Right. There may not be very good reasons for that any more from a technology point of view (there used to be concerns about the impact on cell towers, but that can be solved today with picocells on the planes themselves). But, that still doesn't mean that pilots should be texting while they fly. Is it better or worse than texting while driving? In an age where autopilots do most of the work on landing, perhaps it wouldn't seem like a huge deal, but a Jetstar pilot landing a 220-seat Airbus A320 in Singapore had to abort the landing after realizing he forgot to lower the landing gear, because he was too busy responding to text messages. For whatever reason, the pilots shut off the autopilot, but then got distracted with text messages.
Somewhere between 2500 feet and 2000 feet, the captain's mobile phone started beeping with incoming text messages, and the captain twice did not respond to the co-pilot's requests.

The co-pilot looked over and saw the captain "preoccupied with his mobile phone", investigators said. The captain told investigators he was trying to unlock the phone to turn it off, after having forgotten to do so before take-off.

At 1000 feet, the co-pilot scanned the instruments and felt "something was not quite right" but could not spot what it was.
There followed a series of errors, with the pilot and the co-pilot not communicating with each other -- the pilot trying to drop the wheels as the co-pilot prepared to abort the landing -- and then both pilots becoming confused about their actual altitude. Oh, and then there was the fact that the flaps were set incorrectly.

I'm not necessarily one to bemoan the way people get obsessed with text messaging these days, but I generally think that if you're flying a commercial airplane, and taking it in for landing... it shouldn't be that hard to know that it's a good idea to not worry about your phone for five minutes.

    So the pilots phone was on during the entire flight(or at the very least below the 10,000 foot mark). Since we know that cell towers are designed to fire parallel to the ground, and not perpendicularity to it, the phone had to be already be on well before it got the signal. So making people turn off their phones isn't really required, but who want to explain to people why their cellphones do not work above approximately 2500 feet(actual distance has to do with terrain, tower placement, tower design etc)?

    Also some devices do cause audio interference in speakers. Usually caused by poor line/mic level cabling, or not properly shielded/grounded equipment. This of course points to bad design of the equipment and not the interfering device fault. See part 15 of the FCC rules. So they could use better equipment, but it is easier to blanket ban.

    It is pretty neat to do if you have some cheap desktop speakers (~$10-$15), leave your phone near them and get phone calls. You will learn what the noise is that the speakers make before the cell phone will register anything incoming. It has to do with how well the speakers are built, and what frequency your phone communicates at. Mine will do it when wifi calling and sometimes around the 950 band.
