Sec. 23.207  Stall warning.



    (a) There must be a clear and distinctive stall warning, with the 

flaps and landing gear in any normal position, in straight and turning 

flight.

    (b) The stall warning may be furnished either through the inherent 

aerodynamic qualities of the airplane or by a device that will give 

clearly distinguishable indications under expected conditions of flight. 

However, a visual stall warning device that requires the attention of 

the crew within the cockpit is not acceptable by itself.

    (c) During the stall tests required by Sec. 23.201(b) and Sec. 

23.203(a)(1), the stall warning must begin at a speed exceeding the 

stalling speed by a margin of not less than 5 knots and must continue 

until the stall occurs.

    (d) When following procedures furnished in accordance with Sec. 

23.1585, the stall warning must not occur during a takeoff with all 

engines operating, a takeoff continued with one engine inoperative, or 

during an approach to landing.

    (e) During the stall tests required by Sec. 23.203(a)(2), the stall 

warning must begin sufficiently in advance of the stall for the stall to 

be averted by pilot action taken after the stall warning first occurs.

    (f) For acrobatic category airplanes, an artificial stall warning 

may be mutable, provided that it is armed automatically during takeoff 

and rearmed automatically in the approach configuration.
