I 'partialled' on my PFL as well.The only likely looking field was full of sheep,so I picked a less suitable one and made a right hash of it.The examiner said if thais was a real emergency,I would have to take my chances with the sheep. (perhaps a/c should be fitted with a horn for this situation

)
1 hours revision,straight up with examiner,PFL'd no problem.I alway like to PFL whenever I have an instructor on board (check on type model of a/c etc) and seem to have quelled my fear factor for them.)
Good luck with your retest
