‐ Cruise Mach number M .78/LR
‐ Descent profile M .78/300 kt/250 kt
‐ Approach and landing 110 kg - 6 min IFR

‐ Normal air conditioning
‐ Anti ice OFF
They are based upon a reference landing weight of 50 000 kg.
Note: 1. In the tables, the asterisk (*) means that a step climb of 4 000 ft must be flown to reach
the corresponding FL.
2. To obtain a flight plan at optimum cruise level, the highest flight level desired within the
flight has to be selected in the table.
3. For each degree Celcius above ISA temperature apply fuel correction 0.015 (kg/°C/NM)

INTRODUCTION
Applicable to:
The following flight planning tables allow the planner to determine trip fuel consumption and trip time
required to cover a given air distance.
These tables are established for :
‐ Takeoff
‐ Climb profile 250 kg/300 kt/M .78
‐ Cruise Mach number M .78/LR
‐ Descent profile M .78/300 kt/250 kt
‐ Approach and landing 270 lb - 6 min IFR
‐ ISA
‐ CG = 33 %
‐ Normal air conditioning
‐ Anti ice OFF
They are based upon a reference landing weight of 120 000 lb.
Note: 1. In the tables, the asterisk (*) means that a step climb of 4 000 ft must be flown to reach
the corresponding FL.
2. To obtain a flight plan at optimum cruise level, the highest flight level desired within the
flight has to be selected in the table.
3. For each degree Celcius above ISA temperature apply fuel correction 0.033 (lb/°C/NM) ×
◂ISA (°C) × Air Distance (NM).

CORRECTION FOR DEVIATION FROM REFERENCE LANDING WEIGHT
CORRECTION FOR DEVIATION FROM REFERENCE LANDING WEIGHT
Applicable to: ALL
The fuel consumption must be corrected when the actual landing weight is different from the
reference landing weight.
If it is lower (or greater) than the reference landing weight, subtract (or add) the value given in the
correction part of the table per 1 000 kg below (or above) the reference landing weight.

EXAMPLE
EXAMPLE
Applicable to:
The following is an example of a complete flight plan based on the assumptions :
Zero fuel weight : 60 000 kg = landing ‐ weight at alternate airport
‐ Cruise M .78 at FL 370
‐ Ground distance from departure to destination : 1 800 nm
‐ Average wind during flight : -40 kt (headwind)
‐ ISA conditions
‐ “En route” reserve : 5 %
‐ Ground distance from destination to alternate : 200 nm, no wind at FL 200
To calculate the flight plan, a reverse calculation is needed, i.e. start with the landing weight at
alternate (the schematic Refer to PER-FPL-GEN-FPL FLIGHT PLAN gives an overview of the
calculation to be performed).
1. Alternate fuel and time
‐ Refer to PER-FPL-FLP-ALN-20 ALTERNATE PLANNING ISA ;
Alternate time : 40 min
Alternate fuel : 1 559 + 11 × (60 – 55) = 1 614 kg
2. Holding fuel and time
‐ A 30 min holding is assumed at 1 500 ft. ( Refer to PER-HOL-AEO CONF 0 - GD SPEED),
holding fuel = 1 300 kg
3. At destination, the landing weight = 60 000 + 1 614 + 1 300 = 62 914 kg
4. Evaluation of the air distance between departure and destination.
‐ The “Ground distance/Air distance” conversion table (Refer to PER-OPD-CON-AEO M.78)
shows that the corresponding air distance is : 1 975 nm.
