Can someone here answer these questions: Would a cell phone's GPS chip be operable inside an airplane during flight? Also, would the GPS chip interfere with the airplane's communications? I'm just curious from a technological standpoint.
A cellphone is a radio receiver-transmitter.
An airplane fuselage is a metal can with a few windows in it.
Putting a cellphone in a metal can means it won't work with anything outside very well.
Some signals can sometimes be gained by holding the receiver-transmitter against a window but it's still a very restricted line of sight for the radio.
This is why the airplanes comm system has externally mounted antennas for all radios.
