§29.59 Take-off Path: Category A

(a) The take-off path extends from the point of com mencement of the take-off procedure t o a point at whi ch t he rot orcraft i s 305 m (1000 ft ) above the take-off surface and com pliance with CS 29.67 (a) (2) is shown. In addition: (1) The take-off path m ust remain clear of the hei ght-velocity envel ope est ablished i n accordance with CS 29.87; (2) The rotorcraft m ust be flown to the engine failure point at whi ch poi nt t he cri tical engine m ust be m ade i noperative and remain inoperative for the rest of the take-off; (3) After the critical engine is m ade inoperative, t he rot orcraft m ust cont inue t o the TDP, and then attain VTOSS. (4) Only primary cont rols m ay be used while attain ing VTOSS and whi le est ablishing a positive rate of clim b. Secondary controls that are located on the primary controls may be used after a positive rate of climb and VTOSS are established but i n no case less than 3 seconds after the cri tical engi ne i s m ade i noperative; and (5) After attaining VTOSS an d a p ositive 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 attain ing V TOSS an d a p ositive rate of climb, the climb must be continued at a speed as close as practicable to , b ut n ot less than, VTOSS u ntil th e rotorcraft i s 61 m (200 ft) above t he take-off surface. During this interval, the climb performance must m eet or exceed that required by CS 29.67(a)(1). (c) During the continued take-off the rotorcraft shall not descend bel ow 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 m ust be level or positive until a height 305 m (1000 ft) above the take-off surface is atta ined with not less than the rate of cl imb required by CS 29.67(a)(2). Any secondary or auxiliary control m ay be used after attaining 61 m (200 ft) above the take-off surface. (e) Take-off d istance will b e determined in accordance with CS 29.61.
