Isn't it true that thr airbusses are all fly by wire? If so how would one do in this setting?

The Airbus is"hardned" against hight voltage spikes from both emp and lightning strikes. The computers and various digital wiring is very highly shielded. This is not to say that without proper maintenance that lightning would not affect an Airbus. To date this not been a problem.

The Cessna Citation CE550 is a basic analog airplane. There have been problems in that aircraft with battery relays and other primary power relays. A lightning strike that fried one of these relays could leave the aircraft unpowered. The CE550 was not manufactured or certified to the higher lightning strike requirements of all digital aircraft.

Most relays have large capacitors across their field windings. The capacitors are there to protect the relay windings from voltage spikes. Often these Caps are not changed or checked during maintenance, leaveing the relay suseptable to damage from high voltage.

Just my $.02

Great to get the inside scoop. Thanks, Groucho!
