What makes you qualified to decide what was helpful and what wasn't?
Helpful
1) Where the circuit is
2) When the runway is and what bit to land on.
3) Local knowledge on how best to approach.
4) What not to fly over (noise abatement)
5) Where the loo is (on the ground that is)
Not helpful
1) Procedures which every pilot does but not all in exactly the same way as instructor does
2) Re-training where just a reminder would do
Would they be more like a CAA examiner who says little, gives a few hints at crucial moments and leaves the rest for the debriefing
