We should be teaching what is applicable for the aircraft in question. Any differences on other types should be covered in a type check out.
Wow really? Wish you had been around pre Kegworth.
I hope you will also arrange for all the appropriate PPL technical exams to be made type specific too.
Heard about the instructor who recently sent a solo student to Andrewsfield and she had a radio failure on Box 1 but didnt know that the a/c had two com boxes, I bet he is red hot on type check outs too!
Oh and by the way the OP
is referring to a type check out on a C172 and the fact that his instructor couldnt explain why the check was being made(although i think he has edited this out now). Now there is a surprise, a type check instructor who sounds like he needs a type check himself so he can cover those differences you are talking about!
If you have been in training for any length of time you will know that what should be taught and what is actually taught can be poles apart.
