"It was only an altimeter artifact."
You've had six and a half years to see and conclude that, if true. Similarly UAS was an artifact of AirData. It also fooled the aircraft, but the FCM wasn't sensing the DFDR, either. Was it static sensing?
The culture and twenty years of flying have cultivated "trust the machine".
Anticipation or Skepticism? What difference? Be ready for anything, or start the recovery (too?) late?
Four hundred feet in 5 sec is 4800 feet per minute. Compared to what happened right after, that's docile. The soon to be climb hit 7000 fpm? Turbulence? W/S?
Both reported. By pilots, and ACARS.
