Until a fault tolerant method is developed for obtaining airdata, I hope UAS drills become far more comprehensive in the sim. For three rated pilots to miss the recovery is shocking, assuming BEA isn't leaving out some important tidbits.
Oh, and patch the bugs in the stall warning system for low airspeeds and/or AoA... No doubt that design "feature" should be reclassified as a bug.
Lastly, the man machine interface really needs some review regarding sidestick, thrust lever, and trim positions. When you are 3 minutes from doom you should be given enough information as quickly and comprehendible as possible to take over from Otto when he can't figure it out.
