If there were two things I could change about Air Law in the PPL exams, they would be:
- Change the title to 'Rules of the Air' That's what they are, and many people are put off by the thought of studying 'law'. Someone told me the other day that's what the paper used to be called, but it's so long since I did my PPL exams I can't remember if that's correct.
- Remove questions about things you're highly unlikely to need to know when flying light aircraft - and, in the unlikely event that you do at some point in the future, you probably won't remember anyway. (That also applies to other PPL exams, IMHO.)
