Q

What is the rules regarding AUTO LAND in CAT I or better weather condition?

A

The effect of terrain profile before the runway threshold (300m) is known not to affect the system.

D) Idle reverse is permitted down to aircraft stop.

30
Q

Limits regarding the use of FLEX thrust?

A

Takeoff at reduced thrust is only permitted, if the airplane meets all applicable performance requirements at the planned takeoff weight, with the operating engines at the thrust available for the assumed temperature.

A) Thrust reduction must not exceed 25 % of the full rated takeoff thrust. To meet this requirement, the flexible temperature must not be higher than ISA + 55 °C (T MAX FLEX).

B) The assumed temperature must not be lower than the flat rating temperature, or the current OAT.

C) Takeoff at reduced thrust is not permitted on contaminated runways.

D) Takeoff at reduced thrust is permitted with any inoperative item affecting the performance, only if the associated performance shortfall has been applied to meet all performance requirements at the takeoff weight, with the operating engines at the thrust available for the flex temperature.
