GENERAL
Applicable to:
The alternate planning tables allow the flight crew to determine the fuel consumption and time
required to cover a given air distance from go-around at destination airport to landing at alternate
airport.
These tables are established for :
‐ Go-around : 600 kg or 1 320 lb
‐ Climb profile : 250 kt/300 kt/M .78
‐ Long range speed
‐ Descent profile : .M 80/300 kt/250 kt
‐ Approach and landing at alternate airport : 220 kg or 490 lb (4 min)
‐ ISA
‐ CG = 30 %
‐ Pack flow LO
‐ Anti ice off
Note: 1. In the tables, the asterisk (*) means that a step climb of 4 000 ft must be flown to reach
the corresponding flight level.
2. The flight level shown on the top of each column is the final flight level.
3. For each degree Celsius above ISA temperature apply a fuel correction of 0.015
(kg/°C/NM) × ΔISA (°C) × Air distance (NM)
or 0.033 (lb/°C/NM) × ΔISA (°C) × Air distance (NM)
CORRECTION FOR DEVIATION FROM REFERENCE WEIGHT
Applicable to:
The alternate planning tables are based on a reference landing weight at alternate.
The fuel consumption must be corrected when the actual weight is different from the reference
weight.
If it is lower (or greater) than the reference weight, subtract (or add) the value given in the correction
part of the table per 1 000 kg or 1 000 lb below (or above) the reference weight.

GENERAL
Applicable to:
Fuel tankering graphs allow to determine the optimum fuel quantity to be tankered as a function of
the fuel price ratio between departure and destination airports. The following pages present for one
FL per page the optimum aircraft takeoff weight depending on the fuel price ratio (departure fuel price
divided by destination fuel price) and on the air distance to fly.
The computed optimum takeoff weight is based on the additional fuel consumption needed for
the transport of the extra (tankered) fuel and it is the weight at which the maximum profit can be
achieved. The quantity of extra fuel that can be loaded is calculated as the difference between the
optimum takeoff weight (including extra fuel) and the planned takeoff weight (without fuel tankering).
The graphs are established for :
FL 290, ‐ 310, 330, 350, 370, 390
‐ Air distances from 500 to 7 500 nm
‐ Flight profile :
Climb : 250 kt/300 kt/M .78
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).
