120 - ATPL Question Bank in English - An IFR flight follows a true track of 215 degrees with variation 3 degrees W. Apply the standard magnetic-track semicircular cruising-level table, with no regional or ATC variation. The highest obstacle is 10 600 ft AMSL and the required clearance is 1 500 ft. QNH is 1035 hPa at a sea-level reference aerodrome. Assume a uniform ISA -15 degrees C deviation from that datum to the aircraft, no instrument or position errors, 30 ft per hPa and a 4% height correction per 10 degrees C. What is the lowest flight level satisfying both obstacle clearance and the semicircular rule?
