. Would you, as the QFI, then suspect that your Sqn mates were routinely ignoring the rotate speed that you had so kindly calculated?
Yes.
Normalisation of the deviation is a big problem, especially in small 'elite' units. Monitoring helps prevent it. We had formal interviews and pilots sent home from detachments for cowboy behaviour and cavalier attitudes. The monitoring then was human navigators and they only reported a part of the problem. We lost a crew a year in fatalities, I lost good friends.
