Yeah, at the end of the assessment I asked him how he thought I did and he came back with 'How do you think you did?'
So then had to self evaluate on the spot as he was obviously still assessing at that point. He was a great guy though.
You don't need to know how to fly to pass phase 4. Treat it exactly like a lesson and do whatever the assessor says. They want to see you learn quickly rather than your flying skills
