Hi Chris,
In reply to your post#107 I already admitted in post #109 that I was in error for the time of entry into alpha-protection mode, which is not t-5 but is t-4. I'm on the move right now but will remove the AlphaCmd point at t-5 as soon as I have retrieved my laptop from my luggage.
At 12:45:34 airspeed is122 kIAS and Alpha is 13 degrees is recorded at 329.0s
Five seconds later at 12:45:39 t=0 so that must be at 329.0s + 5 = 334.0s
