Beagle :
All emitting devices used in aeroplanes must be licensed. There is an exmption to this requirement that allows the use of 1800 MHz GSM cellphones in aircraft fitted with pico-cell terminals. Hence no other use of cellphones is lawful in aircraft registered in the UK or flying in UK airspace.
Beagle, I think what confuses me is this. A mobile phone
is a licensed device. So presumably you mean that all emitting devices used in aeroplanes must be licensed
for use in aeroplanes ? And what I cannot see is which part of the act says that ?
