For each commuter category airplane, the accelerate-stop distance must be determined as follows:
The accelerate-stop distance is the sum of the distances necessary to—
Accelerate the airplane from a standing start to VEF with all engines operating;
Accelerate the airplane from VEF to V1, assuming the critical engine fails at VEF; and
Come to a full stop from the point at which V1 is reached.
Means other than wheel brakes may be used to determine the accelerate-stop distances if that means—
Is safe and reliable;
Is used so that consistent results can be expected under normal operating conditions; and
Is such that exceptional skill is not required to control the airplane.
