I haven't seen an answer to the original question, which is
"if airline nav equiptment is so sensitive to RFI, then how much
RFI does it take to mess it up?".  In particular, can ground radios
affect it, or does the faraday cage nature of the cabin keep the RFI
out of the sensitive parts?  And if so, what does that say about the
new composite aircraft (such as LearFan) made of fiber/epoxy (no
Faraday cage effect)?  Also, what about calculators, computers, etc.
I have heard that microprocessors, and radio receivers are banned
for similar reasons, but I have yet to be asked to remove the battery
from my digital watch for the duration of the flight.  What's **REALLY**
going on here?  Is this just the FAA being Pleistocene?
