• ED Decision 2003/16/RM found in: CS-29 Amdt 10 - Large Rotercraft (Jan 2023)

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)](#_DxCrossRefBm1513259334) is shown. In addition: (1) The take-off path must remain clear of the height-velocity envelope established in accordance with [CS 29.87](#_DxCrossRefBm1513259333); (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 VTOSS. (4) Only primary controls may be used while attaining VTOSS 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 VTOSS are established but in no case less than 3 seconds after the critical engine is made inoperative; and (5) After attaining VTOSS 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 VTOSS and a positive rate of climb, 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. During this interval, the climb performance must meet or exceed that required by [CS 29.67(a)(1)](#_DxCrossRefBm1513259334). (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)](#_DxCrossRefBm1513259334). 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](#_DxCrossRefBm1513259348).
