The Definition of Heading Bug
A Heading Bug is a movable index marker commonly found on Heading Indicators that acts as a visual indicator for the desired heading or as an input for the autopilot system. This tool is designed to help the pilot keep track of the selected heading by simplifying the process of referencing and adjusting the aircraft’s heading.
By moving the Heading Bug to the desired heading, the pilot can easily monitor whether the aircraft is on course or needs adjustment. The Heading Bug’s accuracy and dependability help pilots confidently make minor corrections to the aircraft’s heading, providing more precise flight control.
In addition to manual control, some aircraft employ automatic control systems that can use the Heading Bug input to maintain the set heading. The Heading Bug plays an essential role in autopilot systems by setting and maintaining course, resulting in more efficient flight operations and reduced pilot workload.
Overall, the Heading Bug is a vital component of the Head Indicators, providing pilots with an efficient and effective tool for monitoring and adjusting the aircraft’s heading, as well as serving as an essential input for the autopilot system to maintain a stable course.
