There is a potential for EMI to effect the aircraft's IFR under 10,000 feet, so fhey err on the side of caution.
Which is a good thing.

There is a potential for EMI to effect the aircraft's IFR under 10,000 feet, so fhey err on the side of caution.
From a CNN report:
The risk is low
We can find no instance in which electromagnetic interference from a portable electronic device brought down a commercial plane or was a contributing factor in an accident. And the National Transportation Safety Board says it has never issued a recommendation about such devices on planes.
But those who flatly say there's no evidence that electronic devices have caused interference on planes are wrong.
I'm sure that was a stressful moment!However, I've seen first-hand what a cellphone can do when an aircraft is on autopilot.
I was watching an avionics engineer test a new autopilot installation in a light twin-engine aircraft (on the ground), when his phone rang in his pocket. Aircraft went to full nose-down as fast as it could. Certainly an eye-opening experience.
Yep, just lucky it was found on the ground!I'm sure that was a stressful moment!
I know that even an improperly crimped coax on a BNC connector on the back of a VHF radio can mess with the aircraft's instruments.
And EMI is not unique not just aircraft, but I had a fire engine that had a bad PL259 connector on the back of a Kenwood lowband that when keyed, would propegate into the electronic engine controls and rev the engine. Not good - especially when the fire truck was sitting at a stoplight and the engineer had to talk to dispatch.
I thought the Mythbusters proved the interference thingy as false..
And that's the problem with it - you cannot always replicate a confirmed incident to 'prove' it was a cellphone, as there are so many variables in play that a test as simple as what Mythbusters did.Actually, about 10-15 years ago, the UKCAA proved it very real on certain aircraft and under certain conditions.
