Takeoff path.
CFR · 2024-01-01 · US · Title 14
(a) The takeoff path extends from a standing start to a point in the takeoff at which the airplane is 1,500 feet above the takeoff surface, or at which the transition from the takeoff to the en route configuration is completed and V (1) The takeoff path must be based on the procedures prescribed in § 25.101(f); (2) The airplane must be accelerated on the ground to (3) After reaching (b) During the acceleration to speed (c) During the takeoff path determination in accordance with paragraphs (a) and (b) of this section— (1) The slope of the airborne part of the takeoff path must be positive at each point; (2) The airplane must reach (3) At each point along the takeoff path, starting at the point at which the airplane reaches 400 feet above the takeoff surface, the available gradient of climb may not be less than— (i) 1.2 percent for two-engine airplanes; (ii) 1.5 percent for three-engine airplanes; and (iii) 1.7 percent for four-engine airplanes. (4) The airplane configuration may not be changed, except for gear retraction and automatic propeller feathering, and no change in power or thrust that requires action by the pilot may be made until the airplane is 400 feet above the takeoff surface; and (5) If § 25.105(a)(2) requires the takeoff path to be determined for flight in icing conditions, the airborne part of the takeoff must be based on the airplane drag: (i) With the most critical of the takeoff ice accretion(s) defined in Appendices C and O of this part, as applicable, in
