EXAMPLE
Applicable to:
DATA
‐ TO weight : 66 000 kg
‐ Ground distance to destination : 2 000 nm
‐ Wind : –50 kt (head wind)
‐ Selected initial FL : 350
‐ Mach number : M .78
‐ Temperature : ISA +10
DETERMINATION OF CRUISE FUEL AND TIME
A : Enter the chosen flight Mach number, flight level, ground distance to be covered and
forecast windspeed in the calculation table (See CALCULATION TABLE).
Calculate the air distance (Refer to PER-OPD-CON-AEO M.78)
here : M .78, 50 kt head wind, 2 000 nm ground distance

B : Read from integrated cruise table (M .78, FL 350) the values for time and distance for
a weight of 66 000 kg (Refer to PER-FPL-FLP-ICR-20 INTEGRATED CRUISE - M.78
FL350) :

D : Enter integrated cruise table (M .78, FL 350) and read the values for a weight of
62 000 kg (begin of first step climb)

E : Calculate the values for the first cruise segment :
Fuel : 66 000 – 62 000 = 4 000 kg
Distance : 5 599 – 4 813 = 786 nm
Time : 747 – 642 = 105 min
Remaining distance : 2 248 – 786 = 1 462 nm

I : Calculate values for the second cruise segment :
Fuel : 62 000 – 55 100 = 6 900 kg
Distance : 5 203 – 3 741 = 1 462 nm
Time : 698 – 502 = 196 min
Crosscheck that remaining air distance equals zero.
J : Fill in the final table with weight overhead departure (66 000 kg) and weight overhead
destination (55 100 kg).
K : Calculate total values :
Fuel : 66 000 – 55 100 = 10 900 kg
Time : 105 + 196 = 301 min = 5 h 01 min
