FAA Ground School Practice Test

What is an important airspeed limitation that is not color coded on airspeed indicators?

1. Maneuvering speed (Va)

2. Stalling speed (Vso)

3. Maximum structural cruising speed (Vno)

4. Maximum flap extended speed (Vfe)

The correct answer is: Maneuvering speed (Va)

Maneuvering speed (Va) is an important airspeed limitation that is not color coded on airspeed indicators, which typically highlight critical speeds such as stalling speed, maximum structural cruising speed, and maximum flap extended speed with color zones. Va represents the maximum speed at which full deflection of the control surfaces can be applied without risking structural damage to the aircraft. It is crucial for pilots to understand this speed because flying above Va during turbulent conditions can lead to overstressing the aircraft. Since it is dependent on the aircraft's weight, Va can change based on loading, making it more complex than fixed speeds like stalling speed, which is consistent for a given configuration, and is clearly indicated in the color coding for ease of reference. Recognizing that Va is not color coded emphasizes the need for pilots to memorize and automate the calculation of this value based on their current weight, contributing to safe operational practices and decision-making in varying flight scenarios.
