I had not appreciated the extent of the changes in the MAX
Magazine - ALPA
I wonder what other ‘unknown’ system quirks there might be. A ‘fly-by-wire’ spoiler, electrically signalled or computed logic? Landing and emergency descent.
Improved safety appears to be optional; the modifications relate to accidents in each category, but in order to aid the crew you have to pay for the addition. I cannot see that an unstable approach warrants an ‘overrun’ warning; speed / height alert possibly.
Somewhat embarrassing for ALPA in that their pilots apparently did not ‘discover’ MCAS during their lengthy - Boeing paid for, evaluation. This further questions the viability of a computerised differences course and minimum FCOM change.
