Selecting a Flight Level within the Quadrantal Rule
Hi guys,
Sorry if this has been covered to death already and I've missed it, I searched for the answer within the forums but I couldn't find anything other than the basics of the quadrantal rule.
Basically on revision for a PPL exam I have this question (from airquiz.com):
You are intending to fly in accordance with the quadrantal rule on a magnetic track of 120. The QNH is 996 hPa. Which of the following is your correct flight level?
A FL 30
B FL 35
C FL 55
D FL 60
.... I know that a magnetic heading of 120 would require an odd flight level plus 500ft, so it's either B or C. But how do I know which one? What do I do with the QNH to calculate the correct FL?
Thanks very much in advance.
