What is the primary function of the dynamic speed bug in aircraft systems?

The primary function of the dynamic speed bug in aircraft systems is to display target airspeed on the instrument panel. This feature is crucial for pilots, particularly during various phases of flight such as takeoff, climb, cruise, descent, and landing. By presenting the desired airspeed visually, the speed bug helps pilots maintain control over the aircraft's performance and ensures that they are operating within safe and efficient speed parameters.

Displaying the target airspeed can assist pilots in making quick decisions regarding throttle adjustments and other flight controls, enhancing situational awareness and adherence to operational standards. The dynamic aspect indicates that the target airspeed may change based on the current flight conditions, such as changes in weight or altitude, thus providing real-time guidance needed for effective flight management.

This emphasis on maintaining a specific airspeed aligns with various operational guidelines and safety protocols during flight operations, especially under Part 135 regulations where precision in speed management is essential for ensuring the safety and efficiency of commercial operations.
