Sec. 23.1505 — Airspeed limitations.
(a) The never-exceed speed V NEmust be established so that it is— (1) Not less than 0.9 times the minimum value of V Dallowed under §23.335; and (2) Not more than the lesser of— (i) 0.9 V Destablished under §23.335; or (ii) 0.9 times the maximum speed shown under §23.251. (b) The maximum structural cruising speed V NOmust be established so that it is— (1) Not less than the minimum value of V Callowed under §23.335; and (2) Not more than the lesser of— (i) V Cestablished under §23.335; or (ii) 0.89 V NEestablished under paragraph (a) of this section. (c) Paragraphs (a) and (b) of this section do not apply to turbine airplanes or to airplanes for which a design diving speed V D /M Dis established under §23.335(b)(4). For those airplanes, a maximum operating limit speed ( V MO /M MO-airspeed or Mach number, whichever is critical at a particular altitude) must be established as a speed that may not be deliberately exceeded in any regime of flight (climb, cruise, or descent) unless a higher speed is authorized for flight test or pilot training operations. V MO /M MOmust be established so that it is not greater than the design cruising speed V C /M Cand so that it is sufficiently below V D /M Dand the maximum speed shown under §23.251 to make it highly improbable that the latter speeds will be inadvertently exceeded in operations. The speed margin between V MO /M MOand V D /M Dor the maximum speed shown under §23.251 may not be less than the speed margin established between V C /M Cand V D /M Dunder §23.335(b), or the speed margin found necessary in the flight test conducted under §23.253.
