REQUIREMENTS
Applicable to:
Thrust must not be reduced by more than 25 % of ‐ the full rated takeoff thrust.
‐ The flexible takeoff N1 cannot be lower than the Max climb N1 at the same flight conditions.
The FADEC takes the above two constraints into account to determine flexible N1.
The above two constraints also limit the maximum flexible temperature at ISA +53 (68 °C at sea
level).
‐ The flexible takeoff thrust cannot be lower than the Max Continuous thrust used for the final takeoff
flight path computation (at ISA +40).
‐ The flexible temperature cannot be lower than the flat rating temperature, TREF*See ( ISA +29 up
to 2 000 ft ), or the actual temperature (OAT).
Note: * TREF being a function of pressure altitude, read it on the takeoff chart.
‐ Flexible takeoff is not permitted on contaminated runways.
‐ The operator should check the maximum thrust (TOGA) at regular intervals in order to detect any
engine deterioration, or maintain an adequate engine performance monitoring program to follow up
the engine parameters.
