EXAMPLE: LOSS OF CONTROLCS-23.2145 Stall characteristics, stallwarning, and spins

(a) The aeroplane must have controllable stall characteristics instraight flight, turning flight, and accelerated turning flight with aclear and distinctive stall warning that provides sufficient margin toprevent inadvertent stalling.(b) Levels 1 and 2 aeroplanes and level 3 single-engine aeroplanes,not certified for aerobatics, must

(1) Not have a tendency to inadvertently depart controlledflight; or(2) Have a benign behaviour when departing controlledflight; or(3) Have a system preventing departure from controlledflight.

(c) Level-3 multi-engine and all level-4 aeroplanes, not certified foraerobatics, must not have a tendency to suffer a loss of controlafter a likely critical loss of thrust.(d) Aeroplanes certified for aerobatics must have controllable stallcharacteristics and the ability to recover within one and one-halfadditional turns after initiation of the first control action from anypoint in a spin, not exceeding six turns or any greater number ofturns for which certification is requested, while remaining withinthe operating limitations of the aeroplane.(e) Aeroplanes intended for aerobatics have the ability to recoverfrom any manoeuvre, without exceeding limitations or exhibitingunsafe characteristics.
