VNE is established for how many G in straight and level flight?

• A. 1 G
• B. 0.5 G
• C. 1.5 G
• D. 2 G

Answer: (A)

In straight and level flight, the load factor is 1 g—the lift equals weight. VNE is set as the maximum airspeed the helicopter can safely handle at that 1 g condition; it protects the airframe and rotor system from structural overload during normal level flight. If you fly faster than VNE, even small disturbances could push stresses beyond design limits, and during maneuvers or gusts the load factor would rise, demanding an even lower safe speed. That’s why the correct reference for establishing VNE in straight and level flight is 1 g. The other values correspond to higher or lower load factors encountered in non-level or more aggressive maneuvers, which are not the baseline for VNE in straight and level flight.
