I am confused by this practice commercial nav question. ( at least I
am confused by the answer in the book which was b. but I think both a and c are correct), but I appreciate some other opinions. Day 1 Altimeter reads elevation of 1390 feet with 1013 HPa set on subscale ( thats equivalent to 29.92 inches of Hg for the US folks) Day 2 Altimeter reads elevation of 1000 feet Assuming the altimeter subscale was not changed between day 1 and day 2 it could be said that a. The QNH is higher on day 2 b. The QNH is lower on day 2 c. The pressure altitude at the airport is lower on day 2 d. The atmospheric pressure at the aerodrome has not changed. Terry PPL Downunder |
