I am pax of 54 years duration, a nephew is RHS 738.
Whilst I understand that new crew are briefed before an exercise, it was my presumption that experienced in for recurrent session would not.
I thought you briefed for a normal sector and then took whatever the instructor chooses. If my driving instructor briefed me that a motorcycle would overtake towards me on the wrong side of the road, I would not be startled. Learning to manage the surprise factor must be part of the training?
