‐ Flight profile :
Climb : 250 kt/300 kt/M .80
Cruise : M .80
Descent : M .80/300 kt/250 kt
Note: 1. If necessary, step climbs are performed to reach the indicated flight levels.
2. The crew/operator has to verify that the found aircraft weight complies with basic aircraft
limitations (e.g. max fuel capacity) as well as with mission dependent restrictions (e.g.
MLW at destination).
EXAMPLES
Applicable to:
1. Fuel price ratio = 0.917
Cruising
Altitude
= FL 310
Planned TOW = 200 000 kg (mission weight without fuel tankering)
Air Distance = 5 000 nm
Enter graph : Refer to PER-FPL-FLP-FTK FUEL TANKERING - FL310
For the given air distance, the optimum fuel tankering weight is 190 000 kg, which is lower than the
planned􀀃TOW􀀃weight􀀃→􀀃no􀀃fuel􀀃tankering􀀃recommended.􀀃
2. Fuel price ratio = 0.895
Cruising
Altitude
= FL 350
Planned TOW = 200 000 kg (mission weight without fuel tankering)
Air Distance = 1 750 nm
Enter graph : Refer to PER-FPL-FLP-FTK FUEL TANKERING - FL350
For the given air distance, the optimum fuel tankering weight is 225 000 kg, which is 25 000 kg

Check :
a. new TOW less or equal MTOW from departure airport
b. total fuel to be loaded less or equal maximum fuel capacity
c. MLW at destination.
3. Fuel price ratio = 0.830
Cruising
Altitude
= FL 390
Planned TOW = 200 000 kg (mission weight without fuel tankering)
