## CS 25.333 Flight manoeuvring envelope

(See AMC 25.333)

(a) General. The strength requirements must be met at each combination of airspeed and load factor on and within the boundaries of the representative manoeuvring envelope (V-n diagram) of sub-paragraph (b) of this paragraph. This envelope must also be used in determining the aeroplane structural operating limitations as specified in CS 25.1501.

## AMC 25.333(b) Manoeuvring envelope

For the calculation of structural design speeds, the stalling speeds Vs0 and Vs1 should be taken to be the 1-g stalling speeds in the appropriate flap configuration. This structural interpretation of stalling speed should be used in connection with the paragraphs CS 25.333(b), CS 25.335, CS 25.335(c)(d)(e), CS 25.479(a), and CS 25.481(a)(1).
