So you get away with it, maybe dozens of times, but the point missed is that operation of a radio transmitter inside the fuselage from random positions is going to cause equally random inductive pickup in the aircraft wiring system.
Remember that this is a digital pulse signal which will produce equally random effects of the kind outlined in the CAA report.
All transmission equipment that form part of the aircraft installation have external antenna that are placed in positions that are only approved only after extensive testing and evaluation has proven that there is no interaction.
