PilotPieces. As an instructor I teach students that where possible they should choose a field with suitable fields in the overshoot and undershoot to maximize their chances of survival.
As an examiner I attempt to set up the start of the PFL such that amongst other fields a suitable field with an overshoot and undershoot is available. If the candidate selects that field and then ends up high or low and the elects to use the overshoot or undershoot then he would pass the PFL. After all he/she has shown judgement in selecting a field that maximises the chance of survival and has shown further judgement by realising that the aircraft is too high/low and has made a positive command decision to overcome the problem.
