Which airspeed limitation is not color coded on airspeed indicators?

1. Maximum landing speed

2. Stalling speed

3. Maneuvering speed

4. Best climb speed

The correct answer is: Maneuvering speed

The correct answer indicates that maneuvering speed is not typically color-coded on airspeed indicators. The color-coded arcs on airspeed indicators are designed to provide pilots with quick visual references for various operational limits, which can help in maintaining safe flight conditions. Maneuvering speed is a critical airspeed that defines the maximum speed at which a pilot can safely fly a configuration without overstressing the aircraft during flight maneuvers. However, it doesn't have a specific color-coded arc like other airspeeds such as stalling speed or maximum landing speed, which are typically represented by clear demarcations, usually colored in green, yellow, or red. This lack of color coding for maneuvering speed can be attributed to the fact that it is not a fixed value and can vary based on the aircraft's weight. Thus, it is more often listed in the aircraft's operating handbook rather than prominently displayed on the airspeed indicator. Understanding this aspect helps pilots manage their aircraft effectively, particularly during turbulence or when conducting aggressive maneuvers.
