Perpetual Hold File,
Thanks for posting the link. I have read the lab report, and over the next couple of days will critically analyse it, and report back to here, but the good news is that just on the surface of it, it won't take me too much effort to completely discredit their findings. Straight off, the equipment that they tested is old GA stuff, not installed in any fashion like it would be in an aircraft, they blasted the equipment with exaggerated levels of RF radiation from directional antennas. They failed to re-create a realistic senario, and more over made no attempt to duplicate an airliner style situation. What you said about generating the same effects with a piece of iron is correct in the case of the compas, and also I have to ask, what about all the equipment that they didn't test, those that are actually likely to be truly effected by RFI from telephones, that is GPS, DME, TCAS, Transponder, autopilot, IRS............
