Ever wonder why portable electronic devices are prohibited below 10,000 feet on aircraft?
This topic came up this morning when talking with fellow aviation enthusiast, +Zack Zlotnik
, and I thought I'd share the reasoning behind this with the rest of you, since many people don't understand why this rule is in place, or the danger that these devices pose to an aircraft during some of the most critical stages of the flight.
What it really comes down to is this: electronic devices emit electromagnetic fields, which interfere with the sensitive navigational avionics the pilots (and the autopilot) use to get the aircraft safely on the ground.
In one incident involving a 737, use of a portable electronic device was blamed for the localizer (the horizontal component of the ILS) showing full deflection to the right, just after showing that the aircraft was properly lined-up with the runway. After breaking out of the clouds at 2,500 feet AGL, pilots found that they were in fact a full mile off course!Short and simple:
turn off your electronic devices when asked by the cabin crew to do so. The long-winded explanation from the FAA is attached.
