Why do you have to turn off electronics, and even your cell phone, why taking off and landing in an airplane? I know that they CAN interfere with communications, but isnt every electronic FCC regulated ro receive any interference sent its way?

Unfortunately, all such devices put out EMF's (Electromagnetic Fields), which interfere with very sensitive navigation equipment. Since the planes require precise, nearly instantaneous information from their instruments in order to take off and land, it is important to turn off these devices, even when using VFR (Visual Flight Rules). Try placing a cell phone next to a compass, and you'll see the effect.

Supposedly for safety. The thinking used to be such equipement could interfere with the plane's guidance systems, but that doesn't seem to be the case. The FCC will likely relax these restrictions in the near future. They've already started allowing cell phones during certain portions of a flight, which I think is stupid because I don't want to listen to the guy next to me yak for six hours.

It is to prevent the unlikely possibility that it will interfere with the guidance, etc., systems. It usually can't happen, but in the off event that it might, it is a requirement that all electronics that MAY interfere with the avionics be shut down. If your plane ever crashes because somebody didn't do this, you will appreciate this a whole lot more!

I feel the same way....I don't think its the FCC reasoning...I think they claim that the emitance of microwave pulses interfears with the calibration/usage of the GPS computer they use to chart the course both in takeoff, cruise, landing and of course communication. And since all airlines have differnent rules for usage of pc's, CD's, DVD's, cells etc I think this philosophy is a little inflated, but its their planes and their rules..I would love to read a paper or discussion on the subject. maybe somebody out there can furnish a reference. I have also heard that Virgin or somebody will be allowing the use of Cell-phones on flights soon...So again why the rules???

absolute safety standards ( lots of people at risk )
was tested by a Television show and no interference with modern electronics but better safe than sorry ( and the FCC regulates frequencies and transmission strength - but this only applies if the device and its shielding is functioning properly - plus they can't test it they just look at the design specs )

Probably so there will be no interference with the computers and communication systems.
