Which of the following is NOT included in the list of V speeds for the aircraft?

The V speeds are standardized airspeeds that are essential for safe aircraft operation. Each speed has specific significance in terms of aircraft performance and safety.

VFE, or the maximum flap extended speed, indicates the highest speed at which flaps can be safely extended. This is crucial during landing and takeoff phases when flaps are utilized to increase lift at lower speeds.

VY refers to the best rate of climb speed, which is the speed that provides the greatest altitude gain in a given time. Knowing this speed can ensure the aircraft climbs efficiently, particularly in situations where the aircraft needs to gain altitude quickly after takeoff.

VNO is the maximum structural cruising speed, the highest speed at which the aircraft can be safely flown in turbulent air. Operating below this speed helps prevent structural stress during turbulence.

In contrast, VN is not a recognized V speed in aviation, which is why it is the correct answer to this question. The inclusion of V speeds is critical for pilots to determine operational limits and manage aircraft performance effectively. Therefore, VN does not fit into the standard list of V speeds necessary for safe flying.
