Thanks Kiwi but I'm not an instructor. Yet! However, Whirlybird is!!!!
55-60-70 is more like it especially as, how can I put this, one gets older!!! I was 38 when I got my PPL(H) in just under 70 hours. And that is not uncommon in my experience.
Sorry, better get saving. It was a bit disingenuous of your local school to quote minimum hours as being the norm.
Cheers
