skyhighbird,
I had questions just like that in my Air Law exam. I used the Oxford PPL books and their exam prep CD-ROM - and an old Trevor Thom for comparison. Can't comment on the AFE books as I haven't used them.
While the Oxford books and CD were good preparation for the real exam, I was still surprised at the level of minutiae.
It may help to know that the answers are whatever it says in the ANO, ICAO conventions. Exactly what it says. Not similar. Not even the same plus a seemingly logical extra bit.
While all the answers were in my books, a
lot of the questions were on the more obscure and arcane sections of the text.
