DETERMINATION OF MAXIMUM TAKEOFF WEIGHT AND SPEEDS
GENERAL
Applicable to: ALL
The takeoff chart is computed for a given runway under a set of conditions, which are :
‐ OAT
‐ Wind
‐ Configuration
‐ QNH, air conditioning, anti ice...
Two configurations are produced on the chart. This enables the crew to select that giving the highest
permissible takeoff weight. In case of equivalent performance, retain the configuration giving the
lower takeoff speeds.
MTOW DETERMINATION
Applicable to: ALL
Enter the chart with the first configuration and actual wind column reading the temperature value.
This temperature value stands for the OAT. Read the maximum takeoff weight corresponding to
the actual OAT. Note that it is allowed to interpolate between two consecutive lines to obtain the
maximum takeoff weight.
It is reminded that the takeoff weight is the sum of the weight entry and the delta weight. Similarly
determine the takeoff speeds associated with the maximum takeoff weight.
In somes cases, it may happen that the first temperature value (displayed for the highest weight
entry) is higher than OAT. In this case, it is allowed to extrapolate the weight value to avoid
unnecessary penalty. Use the Grad 1/Grad 2 gradients provided at the bottom of the corresponding
column.
CORRECTION TO WEIGHT
Grad 1/Grad 2 are gradients provided for both sides of the flat rating temperature (TREF).
Grad 1 applies to temperatures below TREF and Grad 2 applies above TREF.
Read the lowest temperature of the column (corresponding to the highest weight entry).

If the lowest temperature and OAT are above TREF.
Obtain weight increment by multiplying Grad 2 by the difference in temperature between OAT
and lowest temperature. Add this weight increment to the maximum takeoff weight calculated
for the lowest temperature.
If the lowest temperature and OAT are below TREF.
Obtain weight increment by multiplying Grad 1 by the difference in temperature between OAT
and lowest temperature. Add this weight increment to the maximum takeoff weight calculated
for the lowest temperature.
If OAT is below TREF and lowest temperature is above TREF.
The weight increment is calculated in two steps. Step one is multiplying Grad 2 by temperature
difference between lowest temperature and TREF. Step two is multiplying Grad 1 by
temperature difference between TREF and OAT. Add results from step one and two to
maximum takeoff weight calculated for lowest temperature.
Note: Use the weight gradients only to extrapolate above the maximum weight shown in the
RTOW chart. They are not valid for interpolation between two boxes, between filled
boxes or between one filled and one blank box.
