What is DSP on Boeing 737? (Display Select Panel)

The Display Select Panel (DSP) is an essential component of the Boeing 737 aircraft. It is a multifunctional control panel that allows pilots to interact with various display systems in the cockpit. By using the DSP, pilots can control and select different displays, such as navigation, engine, and systems information, ensuring effective monitoring and control of the aircraft.

The DSP is located on the main instrument panel in front of the pilot and co-pilot seats. It consists of a series of buttons and selectors that enable the pilots to navigate through different display modes and select the desired information for each flight phase. This panel plays a crucial role in providing essential data to the pilots, allowing them to make informed decisions during flight.

Functionality of the Display Select Panel

The Display Select Panel offers several key functionalities that contribute to the efficient operation of the Boeing 737 aircraft. Let’s take a closer look at some of its primary functions:

1. Display Mode Selection

One of the primary functions of the Display Select Panel is to allow pilots to select different display modes to suit their needs during different flight phases. The panel provides options for selecting navigation displays, engine performance data, system status, weather information, and various other parameters critical for safe and efficient flight operations.

For example, during the takeoff phase, the pilots may choose to display the primary flight instruments along with the engine parameters to closely monitor the aircraft’s performance. As the flight progresses, they can switch to navigation displays, weather information, or other desired display modes based on the requirements of the situation.

2. System Configuration

The Display Select Panel also allows pilots to configure various systems and settings of the Boeing 737 aircraft. This includes selecting the desired units of measurement, setting altimeter pressure, configuring the flight management system, and controlling the display brightness and contrast.

Having the ability to configure these settings using the DSP provides flexibility and customization options for the pilots, allowing them to adapt the aircraft’s systems to their preferences and operational needs. It ensures that the cockpit environment remains optimized for excellent situational awareness and ease of operation.

3. Error Fidelity and Error Correction

The Display Select Panel also plays a role in highlighting and correcting errors or faults within the aircraft systems. When an error or fault occurs, the DSP alerts the pilots through visual indications, such as warning lights or error messages on the displays.

The pilots can then use the DSP to acknowledge the error and take appropriate corrective actions. This may involve selecting alternative displays, checking specific system parameters, or communicating with the maintenance team for further troubleshooting and resolution.

Conclusion

The Display Select Panel is a vital control panel in the Boeing 737 aircraft, providing pilots with the ability to select and interact with various display systems. Its functionalities range from display mode selection to system configuration and error fidelity. The DSP enhances pilot situational awareness, enables effective monitoring of critical flight data, and contributes to the overall safety and efficiency of the aircraft.
