OK, kiwiguy, let's compare credentials.
I have been writing and publishing sporadically on the topic of HIRF and its potential influence on avionics for a decade. I have also aided the Canadian TSB in the assessment of HIRF in the investigation into the accident to SW111.
Do you have any education in the physics and engineering of electromagnetic radiation?
Have you read and understood the NASA report on EM fields inside aircraft cabins that is in the TW800 docket? It's a couple of hundred pages long and requires some understanding of 3-dimensional numerical modelling of the Maxwell equations.
Have you read and understood the work that the UK CAA has published on the measured field strengths of cell phone transmissions inside aircraft fuselages?
If so, then we can start to talk seriously about this. If not, then I suggest you do so, so that you will be able to judge what is plausible in the reasoning you propose and what is not.
