331 - ATPL Question Bank in English - In a simplified navigation calculation, an aircraft is at FL150 above an aerodrome of elevation 720 ft. QNH is 1003 hPa and OAT at the aircraft is −5°C. Use standard pressure 1013.25 hPa, 27 ft per hPa, ISA temperature −15°C at FL150, and the 4%-per-10°C rule. Assume the ISA temperature deviation is uniform in the layer and apply the temperature correction to height above the aerodrome. Which listed true-altitude estimate is closest?
