pitch and power
I said it a while back and I'll say it again.
Pitch and power.
The PFD or whatever you want to call it in your EFIS aircraft is 2 separate instruments. Pitot-static tapes and IRS center. If the speed tape is telling you overspeed and the altitude is climbing what is your attitude?
If the PF had only put the thing on the horizon with cruise thrust would they not had a chance of recognising the nature of the failure?
Who needs AOA if they just understand this very basic concept?
