I think it’s different b/c the airbus is electrical. Is that right?
The A3xx series is one of the safest lines of trans continental equipment available. I’d still take a Boeing any day. There were some early problems with fly-by-wire avionics but those were put to bed for the most part in the late 90s.
One thing a lot of people don’t know, is that the first Space Shuttle landing (after being dropped from a modified 747) almost was destroyed to faulty alogrythms in the flight control system (fly-by-wire) while a bunch of dignitaries and Prince Charles observed from the grand stand. The pilot’s quick adjustments confused the programming in the FCS and nearly caused it to careen out of control on the salt flat runway.
But, as i said, i’ll take a 7x7 any day over an Airbus. The A340 which is a beautiful aircraft has some serious problems with tail strikes. Typical European engineering, elegant, effecient but flawed.
Fly by wire is not less safe. It is usually quad redundant, shielded wires delivering electrical impulses to command hydraulic servoactuators. Very safe with good inspection schedules.
