IR Implementing rule

## CS 23.2115 Take-off performance

(a) The applicant must determine aeroplane take-off performance accounting for:

(1) stall speed safety margins;

(2) minimum control speeds; and

(3) climb gradients.

(b) For single-engine aeroplanes and Levels 1, 2, and 3 low-speed multi-engine aeroplanes, take-off performance includes the determination of ground roll and initial climb distance to 15 m (50 ft) above the take-off surface.

(c) For high-speed multi-engine aeroplanes of Levels 1, 2, and 3, and for all Level-4 multi-engine aeroplanes, take-off performance includes a determination of the following distances after a sudden critical loss of thrust:

(1) an aborted take-off at critical speed;

(2) ground roll and initial climb to 11 m (35 ft) above the take-off surface; and

(3) net take-off flight path.
