Wiz, while I fully agree with you that one must leave the hand on the thrust levers, what exactly would you accomplish by failing the candidate?
They would have to go on Day 2, extra sim, whatever to "learn it" after practicing say 2/3/4/10 times? What would this accomplish?
Why not a strong advice from your expertise as a TRE on why is so important to leave the hands on the thrust levers and give them the infamous "3"?
Not judging just asking...
In a training session- yes.
In an examination-no.
