The Course Heading Select Panel, abbreviated as CHSP, is an essential component of the cockpit in the Boeing 737 aircraft. It is a control panel that allows the pilots to input and modify the desired course heading of the aircraft during the flight. The CHSP is located on the center pedestal, between the pilot and co-pilot seats, providing easy access and visibility.
The CHSP is responsible for initiating and controlling the automated navigation features of the Boeing 737. It is connected to the Flight Management System (FMS), enabling the pilots to select and change their desired course or route. By using the CHSP, the pilots can input the desired course heading in degrees, which then engages the autopilot to follow that specific path.
Moreover, the CHSP also allows the pilots to make adjustments or corrections to the course heading during the flight. This flexibility is particularly useful in situations where the pilots need to deviate from the planned route due to air traffic control instructions, weather conditions, or other operational considerations.
The CHSP is equipped with various controls and indicators that assist the pilots in managing the aircraft’s course heading. Let’s explore some of the key features of the Course Heading Select Panel.

Key Features of the Course Heading Select Panel
1. Course Heading Selector Knobs
The Course Heading Select Panel consists of a pair of selector knobs, one for the pilot and the other for the co-pilot. These knobs are used to input the desired course heading in degrees. The increments on the knobs usually range from 1 to 10 degrees, allowing precise adjustments to the course. The pilot and co-pilot can independently control their respective selectors to ensure coordinated inputs.
Once the desired course heading is dialed in using the selector knobs, the pilots can confirm their selection through the associated digital display on the panel.
2. Course Heading Indicator
Adjacent to the selector knobs, the Course Heading Select Panel features a Course Heading Indicator. This indicator displays the current course heading of the aircraft. It provides real-time information to the pilots, allowing them to cross-reference their input with the actual heading of the aircraft. This ensures accuracy and helps the pilots detect any discrepancies or errors in the selected course.
The Course Heading Indicator is designed to be highly visible and easily readable, even in varying lighting conditions within the cockpit.
3. Autopilot Engagement Button
At the center of the Course Heading Select Panel, there is an autopilot engagement button. This button allows the pilots to engage the autopilot system upon selecting the desired course heading. Once engaged, the autopilot takes control of the aircraft’s flight controls and ensures that the aircraft follows the selected course.
By integrating the autopilot engagement with the Course Heading Select Panel, the pilots can easily transition from manually controlling the aircraft to the automated flight mode. This improves the overall efficiency of the flight deck operations and reduces the workload on the pilots.
The Course Heading Select Panel is a crucial component in the Boeing 737 aircraft, enabling the pilots to accurately set and adjust the course heading of the aircraft. The integration of this panel with other flight management systems and autopilot ensures a seamless and precise navigation experience during flight.
The Course Heading Select Panel plays a vital role in flight navigation, contributing to the overall safety and efficiency of the aircraft. Its importance can be understood by examining its functions and benefits:
Accurate Course Selection
By incorporating the Course Heading Select Panel, the pilots can precisely input the desired course heading for the aircraft. This accuracy is crucial for maintaining the planned route and avoiding any potential conflicts with other aircraft or restricted airspace zones.
The ability to select the course heading in degrees ensures that the pilots have full control over the aircraft’s intended path and allows for easy adjustments as required.
Automation and Workload Reduction
With the Course Heading Select Panel’s integration with the autopilot system, the pilots can engage the automated flight mode once the desired course heading is selected. This automation significantly reduces the workload on the pilots, allowing them to focus on other important aspects of the flight, such as monitoring the systems and communicating with air traffic control.
Moreover, the autopilot system ensures a more stable and precise flight, reducing the chances of human errors and improving overall safety.
Flexibility for Route Adjustments
The Course Heading Select Panel provides the pilots with the flexibility to make route adjustments during the flight. This is particularly valuable in scenarios where unexpected changes in weather conditions, air traffic congestion, or operational requirements necessitate route deviations.
By easily inputting a new course heading through the CHSP, the pilots can ensure a smooth transition to the revised route, enhancing efficiency and minimizing delays.
In conclusion, the Course Heading Select Panel is an integral part of the Boeing 737 aircraft’s navigation system. Its purpose is to allow the pilots to accurately input and adjust the desired course heading, facilitating the automated flight mode and improving the overall safety and efficiency of the aircraft.
