Here are a few questions from oxford school regarding instrumenation which,
actually, are not that hard but i prefer to ask for advise before submitting my
assessment.
Don't ask here - submit you answers and the school will respond.
The whole point of such questions is to see if you have correctly assimilated the information in the relevant section(s) of the notes.
You will never pass the ATPL exams by using the "experts" on this site.
