Yes I was low.
No it wasn't my instructors fault, my being low wasn't a deliberate act on his part.
It wasn't a deliberate act on his part ?
He was your INSTRUCTOR ! Surely he must have had more than enough experience to see what was happening and to tell you to sort yourself out much earlier in the approach ?
Maybe I'm in dreamland, but surely the job of an instructor is to teach and ingrain good habits. Sure by all means let a student learn from their mistakes if the student likes that sort of learning, but this is one scenario where the safety should have come first !
