Winnerhofer,
“Additionally, the autopilot doesn’t just click off when the going gets tough but enters an extended protection envelope where it will attempt a recovery back to the normal flight envelope. This extended envelope includes extremes in speed, AOA, pitch (50° up!) and bank (120°). Indeed, the A350;s autopilot can remain engaged (or be reengaged) even in cases of dual engine failure, complete hydraulic failure and emergency electrical configuration!”
As an answer to 447? Save TRIM, wasn’t the 330 eminently controllable with loss of (displayed) speeds? Wasn’t the loss of data the exact reason the Autopilot quit?
So, with bad airdata, autoflight is a good idea?
