CS 29.59 Take-off Path: Category A

Q: What is the minimum height above the take-off surface at which the take-off path for a Category A rotorcraft is considered to end?

The take-off path extends to a point at which the rotorcraft is 305 m (1000 ft) above the take-off surface and compliance with CS 29.67(a)(2) is shown.

Q: Which controls are permitted to be used while attaining VTOSS and establishing a positive rate of climb?

Only primary controls may be used while attaining VTOSS and while establishing a positive rate of climb.

Q: At what point during the take-off path may the landing gear be retracted?

After attaining VTOSS and a positive rate of climb, the landing gear may be retracted.

Q: What speed must be maintained during the climb from VTOSS until the rotorcraft is 61 m (200 ft) above the take-off surface?

The climb must be continued at a speed as close as practicable to, but not less than, VTOSS until the rotorcraft is 61 m (200 ft) above the take-off surface.

CS 29.59 Take-off Path: Category A

ED Decision 2003/16/RM

(a) The take-off path extends from the point of commencement of the take-off procedure to a point at which the rotorcraft is 305 m (1000 ft) above the take-off surface and compliance with CS 29.67(a)(2) is shown. In addition:

(1) The take-off path must remain clear of the height-velocity envelope established in accordance with CS 29.87;

(2) The rotorcraft must be flown to the engine failure point at which point the critical engine must be made inoperative and remain inoperative for the rest of the take-off;

(3) After the critical engine is made inoperative, the rotorcraft must continue to the TDP, and then attain V_TOSS.

(4) Only primary controls may be used while attaining V_TOSS and while establishing a positive rate of climb. Secondary controls that are located on the primary controls may be used after a positive rate of climb and V_TOSS are established but in no case less than 3 seconds after the critical engine is made inoperative; and

(5) After attaining V_TOSS and a positive rate of climb, the landing gear may be retracted.

(b) During the take-off path determination made in accordance with sub-paragraph (a) and after attaining V_TOSS and a positive rate of climb, the climb must be continued at a speed as close as practicable to, but not less than, V_TOSS until the rotorcraft is 61 m (200 ft) above the take-off surface. During this interval, the climb performance must meet or exceed that required by CS 29.67(a)(1).

(c) During the continued take-off the rotorcraft shall not descend below 4.6 m (15 ft) above the take-off surface when the TDP is above 4.6 m (15 ft).

(d) From 61 m (200 ft) above the take-off surface, the rotorcraft take-off path must be level or positive until a height 305 m (1000 ft) above the take-off surface is attained with not less than the rate of climb required by CS 29.67(a)(2). Any secondary or auxiliary control may be used after attaining 61 m (200 ft) above the take-off surface.

(e) Take-off distance will be determined in accordance with CS 29.61.
