Just As I Thought!
I had a student going into his skills test a couple of days ago and we had to do an additional flight to make up his time to 45 hours on the examiner say so. So I rang PLD and the chap and at the end of the phone there said 45 hours to do the skills test but to be honest, he didn't sound very sure (he sounded very new to it actually) hence why I have posted here.
All now makes much more sense, thanks guys.
