first value applies to all temperatures less than or equal to ISA + 15. The second value applies to ISA
+ 40. For a temperature between ISA + 15 and ISA + 40, interpolate linearly between the two given
speeds.
The speeds in the tables are checked for VMCA limitation.
Note: The minimum V2 speed due to VMCA is given on the RTOW chart.

For OAT lower than the lowest temperature value of a wind column, it is possible to obtain a higher
maximum permissible takeoff weight by using Grad 1/Grad 2 values. Refer to PER-TOF-TOC-18-10

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 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.
