That I have no idea of. Did you notice that I said “I am not sure how this would affect the Airbus - fly by wire aircraft If your Smart phone must be turned off for takeoff and landing they are susceptible to radio waves, I presume. I don’t know anything about Airbus aircraft except I have waited in line behind them to takeoff.
“If your Smart phone must be turned off for takeoff and landing they are susceptible to radio waves, I presume.”
Unfortunately, that presumption has been around even in the aviation community. However, I can guarantee you there has not been a single incident of a smartphone interfering with flight control systems or even navigation systems. In fact, the FAR, Federal Aviation Regulations, in no way require devices to be turned off. The FAR simply gives the PIC, Pilot in Command, the authority over that decision. The FCC disallows phones in the air to protect cell towers from being bombarded by signals at altitude where phones may hit dozens or even hundreds of towers at once. Cell system operators asked for that regulation.
