How I enjoyed learning about that mainstay of modern approach aids, the Microwave Landing System!
Think yourself lucky, Loran and Decca were still included when I did them!!Please tell me they have been removed now?!?!
TIMU below is 100% correct, rote learning the likes of what year such and such convention was ratified in what country for Air Law is bloomin pointless and takes up time you could be paying more attention to things that might save your life one day.
I passed my ATPLS with an avg of 90% (was one of the first bunch to sit JAR exams) but only got 76% for Air Law and that still felt like 1% too much study time I'd wasted!
