The answer is probably because their standard is consistent (although the emergencies training is almost certainly better). Just a look at this thread kind of proves the point - how many names actually came out of the hat in answer to the original request? There should be loads of them!
The scariest thing that myself and my instructors have noticed is how inconsistent the standard of core knowledge is, that should apply acroos the board from PPL(H) to ATPL(H). In fact, it should not be that big a hop between PPL(H) to CPL(H).
The fact is that there are flying schools who are simply not doing the ground instruction properly. I understand that flight instructors are only paid to fly, but I don't think that is an excuse in the final analysis. I also understand that there are some students who simply treat the exams as a nuisance factor, but the amount of people who turn up at the safety meetings prove that there are people who want to learn properly, which is why we will be starting PPL(H) ground study classes during evenings and weekends at Wycombe in the very near future.
Transport Canada is very hot on basic training, and I think JAA/EASA should be too.
