I am very curious about this one.
I am a radio engineer working within GSM/PCS and also a qualified helicopter pilot.
Why you cannot use mobile phones while flying is beyond me? I had first assumed that if you have 100 mobiles all transmitting at once then the RF energy could create problems for the FBW or such like. After some research and reflection I thought that if it is that easy to screw up FBW or navigation systems in modern AC then I definitely don’t want to be flying in one! So what is the reason? I don’t know.
So is anyone out there who can give me a good well rounded scientific argument for banning the use of mobile phones on aircraft? And while we are at it why on BMI, for example, can you use your phone until doors closed but on easyjet you cannot use it at all once boarded?
I am genuinely curious for the answers to these ones.
