Simple example if AF447 had maintained existing pitch at 3 deg. NU, 70%N1 power (approx) and GS 460 kts (whatever it was at the time of failure) nothing would have happened. Safe flight for the foreseeable future. If GS fell by 30 kts say, then apply thrust back to 460 GS and readjust power to 72% and so on.
If anyone thinks this wouldn’t work perfectly please say why.
Cheers and thanks for keeping this thread calm.
