Sec. 23.55  Accelerate-stop distance.

    For each commuter category airplane, the accelerate-stop distance 
must be determined as follows:
    (a) The accelerate-stop distance is the sum of the distances 
necessary to--
    (1) Accelerate the airplane from a standing start to VEF 
with all engines operating;
    (2) Accelerate the airplane from VEF to V1, 
assuming the critical engine fails at VEF; and
    (3) Come to a full stop from the point at which V1 is 
reached.
    (b) Means other than wheel brakes may be used to determine the 
accelerate-stop distances if that means--
    (1) Is safe and reliable;
    (2) Is used so that consistent results can be expected under normal 
operating conditions; and

    (3) Is such that exceptional skill is not required to control the 
airplane.
