What is committed at indicated air speeds at or above s1? | The takeoff is committed at indicated air speeds at or above S1. |
If an engine failure occurs prior to obtaining S1 and action is taken to stop the aircraft before obtaining S1, what capability is assured? | If an engine failure occurs prior to obtaining S1 and action is taken to stop the aircraft before obtaining S1, takeoff abort capability is assured. |
when and what must be equal to or greater than the higher of ground minimum control speed or critical engine speed failure. | In take-off planning, S1 is equal to or greater than the higher of ground minimum control speed or critical engine failure speed. |
What three things must S1 not be higher than the lowest of? | However, S1 must not be higher than the lowest of refusal speed, rotation speed, or maximum braking speed. |
If S1 is higher than the lowest of refusal speed, rotation speed, or maximum braking speed... what do you do? | If it is higher, the take-off weight must be reduced until this requirement is met |
