I find it difficult to believe software is Airbus’ competitive edge. First, their software for aircrew bidding is an absolute and utter disaster. Date filtering has been broken nearly a year despite multiple releases being pushed. Date management is like THE KEY functionality of aircrew bidding. I also use their flight plan software and it’s like they never bothered to ask a pilot how they use a flight plan in flight.

I think Airbus is riding the coat tails of solid engineering done in the 80s and continuing to iterate that platform vs Boeing trying to iterate on a hardware platform from the 60s. Airbus benefited significantly from 20s years of engineering and technological progress. Since the original design of the A320, changes have been incremental. Slightly different engines, addition of GPS/GNS, CPDLC, CRT to LCD screens. Meanwhile Boeing has attempted to take a steam gauge design from the 60s and retrofit decades of technology improvements and, critically, they attempted to add engines significantly altering the aerodynamics of the aircraft.
