What is RST on Boeing 737? (Reset)

When it comes to aviation technology, every aircraft has its fair share of complex systems and procedures. The Boeing 737, one of the most widely-used aircraft in the world, is no exception. One important term that often comes up in discussions about the Boeing 737 is “Reset” or RST. In this article, we will explore what Reset means in the context of the Boeing 737, why it is crucial, and how it is performed.

Reset on the Boeing 737 refers to a procedure that allows the aircraft’s systems to return to their initial state or default settings. It is an essential step when troubleshooting various system anomalies or faults. When an issue occurs, Resetting the affected system can sometimes resolve the problem by clearing any temporary inconsistencies or errors that may have occurred.

The Reset procedure can be initiated by the flight crew or the maintenance team, depending on the specific situation. Once Reset is performed, the system undergoes a self-check to ensure all components are functioning correctly, and any faulty or abnormal conditions are rectified.

The Importance of Reset on the Boeing 737

Resetting various systems on the Boeing 737 is crucial for several reasons:

1. Detecting and Resolving Temporary Faults: Resetting a system can help identify and rectify temporary faults that may be causing abnormalities or malfunctions. By resetting the system, it allows the aircraft to re-evaluate itself and reestablish normal functionality, potentially clearing any temporary glitches.

2. Safeguarding System Integrity: Performing a Reset helps ensure that the integrity of the affected system is restored. In-flight, the Boeing 737 relies on various systems for critical functions such as navigation, communication, and control. Resetting these systems when needed ensures they are working optimally, reducing the risk of potential issues.

3. Minimizing Flight Disruptions: Resetting the appropriate system can often resolve minor issues without the need for extensive troubleshooting or maintenance. This can help minimize flight disruptions, allowing the aircraft to remain operational and reducing the impact on passenger schedules.

How Reset is Performed

The Reset procedure on the Boeing 737 involves a series of steps:

1. Identifying the Affected System: The first step in performing a Reset is identifying which system is experiencing the issue. This can be determined by the flight crew or maintenance team based on indications, alarms, or abnormal system behavior.

2. Locating the Reset Switch or Procedure: Once the affected system is identified, the next step is finding the Reset switch or procedure specific to that system. Each system on the Boeing 737 may have a different method of Reset, which is outlined in the aircraft’s documentation provided by the manufacturer, Boeing.

3. Performing the Reset: After locating the appropriate Reset switch or procedure, it is executed as per the manufacturer’s instructions. This typically involves pressing a designated button, turning a switch, or following a step-by-step process outlined in the documentation.

4. System Self-Check: Once the Reset is performed, the system undergoes a self-check to verify its proper operation. This self-check ensures that all components within the system are functioning correctly and any faults or anomalies are resolved.

It is important to note that the Reset procedure should only be performed after thorough evaluation and consideration by trained personnel to ensure it is the appropriate action for the given situation.


Resetting various systems on the Boeing 737 is a crucial part of troubleshooting and maintaining the aircraft’s optimal performance. It helps detect and resolve temporary faults, safeguard system integrity, and minimize flight disruptions. By following the manufacturer’s instructions and considering the specific situation, Reset can be performed effectively to address system anomalies. It is an essential procedure that contributes to the safe and efficient operation of the Boeing 737.
