I think I said it'd do jack to an aircraft without any tech reason my apologies, just opinion , however my opinion is based on the extraordinary wavelengths of the actual radio signal at vlf freq's.A full wave at 19.8 kilohertz is over 15,000 metres in length if my maths is correct.
Antennae will function at any length for receiving just the efficiency suffers (tx'ing is another issue) but a resonant antenna is best.1/4 wave is widely used and still works well.Even at 1/4 wavelength an antenna is nearly 4 kilometres in length.One can shorten an antenna hugely but I think you get the point I'm making.
I understand some video /pc monitors produce a lot of vlf "noise" so I would hazard a guess that the shielding and filtering to prevent or at least minimise the opportunity for stray RF to interfere with computer ops would be very low as its a known issue.I would say that filtering and shielding would be the best arguments against vlf interference as the source of trouble.
With powerful transmissions the front end of a radio or electronic equipment can be open to brute force but given my above theorising and the fact fbw aircraft have been flying around these for years without apparent problems leads me to that conclusion.But like I said elsewhere I've never seen an oxy cyl explode in situ let alone go thru the cabin floor and exit the hole in the floor and out of the aircraft either.
I'm a mug punter with quite a few years in the industry but not for one moment would I suggest am 100% correct or even 10% , just offering an opinion to a very good question.
