Hi guys I pondered this for some time and I suspect there may be an error in one of the questions:
Question 11 in Sample Questions-Set 3 pp147
An aircraft that is overtaking another aircraft shall do so by
(a) climbing
(b) descending
(c) altering its heading to the right
(d) altering its heading to the left

I chose answer (c) but the published correct answer is (a). Am I missing something or is it a misprint?

CAR 162 [3] states:
An aircraft that is being overtaken has the right-of-way and the overtaking aircraft, whether climbing, descending, or in horizontal flight, shall keep out of the way of the other aircraft by altering its heading to the right, and no subsequent change in the relative positions of the two aircraft shall absolve the overtaking aircraft from this obligation until it is entirely past and clear.

Cheers
Andy
