Applicable to: ALL
For a takeoff weight lower than those displayed on the chart, associated speeds are calculated as
follows :
1. For a given configuration and wind, note the speeds associated with the takeoff weight in the row
displaying the highest permissible temperature.
2. Apply a speed correction provided at the bottom of the RTOW chart to V1, VR and V2 limited to
minimum speeds.

MAXIMUM STRUCTURAL TAKEOFF WEIGHT
MAXIMUM STRUCTURAL TAKEOFF WEIGHT
Applicable to: ALL
The maximum structural takeoff weight is a weight limitation depending on the aircraft. This limitation
is provided in the Flight Manual and in the chapter limitation of the FCOM. Compare the maximum
structural takeoff weight to the maximum permissible takeoff weight computed for given conditions
and retain the lower of the two values.

DEFINITION OF FLEXIBLE TAKEOFF
DEFINITION OF FLEXIBLE TAKEOFF
Applicable to: ALL
In many cases the aircraft takes off with a weight lower than the maximum permissible takeoff
weight. When this happens, it can meet the required performance (runway, second segment,
obstacle,...) with a decreased thrust that is adapted to the weight : this is called FLEXIBLE TAKEOFF
and the thrust is called FLEXIBLE TAKEOFF THRUST.
The use of flexible takeoff thrust saves engine life.

USE OF FLEXIBLE TAKEOFF
USE OF FLEXIBLE TAKEOFF
Applicable to: ALL
The pilot can use flexible takeoff when the actual takeoff weight is lower than the maximum
permissible takeoff weight for the actual temperature. The maximum permissible takeoff weight
decreases when temperature increases, so it is possible to assume a temperature at which
the actual takeoff weight would be the limiting one. This temperature is called FLEXIBLE
TEMPERATURE or assumed temperature and is entered in the FADEC via the MCDU PERF TO
page in order to get the adapted thrust.
