Based on: Emergency descent to 10000 ft. Level cruise at 10000 ft. 250 KIAS descent to 1500 ft. 15 minutes
hold at 1500 ft. One missed approach; approach and land. 5% allowance for wind errors.
Increase fuel required 0.5% for each 10°C hotter than ISA conditions.
If icing conditions exist, increase fuel by 15% to account for engine and wing anti-ice on (7%) and ice
accumulation on unheated surfaces (8%).
Allowance for performance deterioration not included.
Compare the fuel required from this chart with critical fuel reserves for one engine inoperative.
Use the higher of the two.
