Q77 must be wrong.
The question can be paraphrased as "19kt wind, a/c certified for 15kt crosswind. How many degrees off the runway can the wind be before the crosswind component is too large". Answers given are (a) 30 deg, (b) 45 deg, (c) 60 deg and the Confuser claims (c) is the right answer. However when the crosswind component is 15kt triganometry gives
sin theta = (15/19) so
theta = 52 deg. However, that makes none of the answers correct - although I guess (b) is least wrong. 60 degrees gives an out-of-limits 16.5kt crosswind component. 45 degrees gives 13kt.
Q86 just seems vague.
Subject to the interpretation of the question there seem to be two correct answers. The question is a bit long to reproduce here, but I don't think that the Confuser answer is
wrong - but it
does depend on how you read it. However, the other 'correct' answer does seem to be hard to argue with.
Oh, and Question 38 doesn't make any sense with an up to date chart
BTW, the real exams suffer from the odd vague question too, so it's not just the Confuser...
