Descent to cruise level : (FL 220)
(Refer to PER-DES-OEI-STD DESCENT - M.78/300KT - 1 ENGINE OUT)
Distance = 240 - 151 = 89 nm
Fuel = 1 307 - 876 = 431 kg
Time = 36.4 - 24.0 = 12.4 min
Cruise at long range speed (FL 220) to landing
(Weight = 68 000 - 431 = 67 569 kg : Distance = 540 - 89 = 451 nm)
Determine on (Refer to PER-CRZ-OEI-ICQ-10 IN CRUISE QUICK CHECK LONG RANGE) time
and fuel consumption at ISA conditions and for a reference weight of 55 000 kg. Interpolate the
remaining air distance of 451 nm at FL 220.
Fuel : 2 412 kg
Time : 1 h 27 min
Correction due to actual in-cruise weight
◂Fuel = +23 kg per 1 000 kg above reference weight
◂Fuel = +23 kg × (67.6 – 55) ~ 290 kg
RESULT
Total Fuel = 431 + 2 412 + 290 = 3 133 kg
Time = 1 h 27 min + 13 min = 1 h 40 min
