Penalty for not keeping the speed¶
It is taken when the +10/-5 kts limits of the V2+ speed, which is recorded by FDR and displayed in the "Systems" menu at the bottom left, have exceeded 3 seconds after cutting off the ground to comply with the noise abatement procedures and reflect the take-off energy to the climb ultimately.
For the pilot to control this speed, it is expected to calculate the take-off N1 value, flex (derated) take off if possible, and give the nose angle up to do not exceed the limits after taking off. It is tolerated for 3 seconds when the limits are exceeded. Not required on VFR flights. (New)
