Static takeoff vs rolling takeoff
Hi,
Takeoff procedure 1: Engines at idle and brakes on. You release the brakes and then you advance the throttles to an intermediate thrust setting (40%N1 or 50%N1, EPR?). Once you reach this thrust on all engines, you apply takeoff thrust.
Takeoff procedure 2: With the brakes on and engines at idle you advance the throttles to an intermediate thrust setting. Once you reach this thrust on all engines, you release the brakes and then you apply takeoff thrust.
Are both takeoff procedures (1&2) considered static takeoff?
Reading from some posts, it seems the rolling takeoff is the recommended procedure. Is this true? Or is it up to the crew to decide between the rolling and the static takeoff?
Is it recommended to apply the 2 steps takeoff procedure (intermediate thrust: 40/50 N, then takeoff thrust) on both types of takeoff procedure?
When and how often the static takeoff is used (besides short runway)?
Feedback appreciated.
