Based on: Emergency descent to 10000 ft, level cruise at 10000 ft, 250 KIAS descent to 1500 ft, 15 minutes
hold at 1500 ft, approach and land.
Increase forecast headwind or decrease forecast tailwind by 5%.
Increase fuel required 0.8% per 10°C above ISA.
When icing conditions are forecast use the greater of the engine and wing anti-ice on (2%) for the total fore-
cast time or engine and wing anti-ice on and ice drag (12%) for 10% of the forecast time.
Compare the fuel required for all engine and engine inoperative critical fuel reserves and use the higher of
the two.
