You probably already read my post as well, about a prototype Concorde wagging its tail when talking on the HF... the yaw rate gyros were sitting just under the HF aerials... two slots in the vertical fin... not all that efficient, so a lot of HF currents in the surrounding structure. Solved with a few ferrite cores in the right place.
Of course all the above and others I encountered were because of EMI sources being in close proximity to the units affected. still, with the sophistication now, no surprise if something like a very powerful VLF source could affect some computers.
Check back to my earlier post about the field strength. To me it simply made no sense... even the 400Hz field strength in the aircraft is probably higher.
