The V-speed that denotes the normal operating range is?

• A. V/NO
• B. V/FE
• C. V/LE
• D. V/S0

Answer: (A)

The normal operating range is the speed band where the airplane can fly safely in normal conditions without stressing the structure. It runs from the stall speed in clean configuration up to the maximum structural cruising speed. The speed that marks the upper limit of this range is Vno. That’s why Vno is the best answer here.

Other speeds relate to different limits: Vfe is the maximum speed with flaps extended, Vle is the maximum speed with the landing gear extended, and Vs0 is the stall speed with flaps down. They don’t define the upper boundary of the normal operating range.
