What is RSP in Aviation? (Reversion Switch Panel)

Updated: March 09, 2024

The Reversion Switch Panel (RSP) in Aviation

Aviation is a complex industry that relies on a multitude of systems and instruments to ensure safe and efficient flight operations. One such crucial component is the Reversion Switch Panel (RSP), also known as the RSP. The RSP plays a vital role in aircraft systems, providing pilots with the ability to switch between various modes and reversionary configurations. In this article, we will explore the functionality and significance of the Reversion Switch Panel in aviation.

Understanding the Reversion Switch Panel (RSP)

The Reversion Switch Panel, or RSP, is a control panel located within the cockpit of an aircraft. Its primary purpose is to enable pilots to switch between different modes and configurations of various aircraft systems. The RSP allows for smooth transitions between different operational states, ensuring continuous functionality of critical systems.

The Reversion Switch Panel typically consists of a set of switches, buttons, and indicators. These controls are designed to facilitate the selection and activation of specific system configurations. The RSP may be used to switch between different flight control laws, display formats, or navigation modes, depending on the specific aircraft and its systems.

One of the key features of the Reversion Switch Panel is its ability to provide pilots with access to reversionary modes. Reversionary modes are backup or alternative configurations that can be activated in the event of a failure or abnormal operation of primary systems. By using the RSP, pilots can quickly and seamlessly transition to these backup modes, ensuring continued control and operation of the aircraft.

Functionality and Significance of the Reversion Switch Panel

The Reversion Switch Panel plays a critical role in aviation by providing pilots with essential control and reversionary capabilities. Here are some of the key functions and significance of the RSP:

System Redundancy: The RSP allows for redundant system configurations, ensuring that pilots have backup options in case of a failure in primary systems. This redundancy greatly enhances the safety and reliability of the aircraft.
Flight Control Adaptability: The RSP enables pilots to adapt the flight control laws of the aircraft to suit different flight conditions or operational requirements. This adaptability ensures optimal performance and maneuverability.
Display Flexibility: With the help of the RSP, pilots can switch between different display formats, such as primary flight displays (PFD) and multifunction displays (MFD). This flexibility allows for better situational awareness and information presentation.
Navigation and Communication Modes: The RSP also allows pilots to select and switch between various navigation and communication modes. This functionality is crucial for efficient air traffic management and communication with ground control.
Emergency Response: In the event of an emergency, the RSP can be used to activate emergency configurations and procedures. This quick access to essential controls can help pilots respond effectively and mitigate critical situations.

Overall, the Reversion Switch Panel is a vital component of an aircraft's avionics system. Its functionality and significance in providing control, redundancy, and adaptability make it an essential tool for pilots in ensuring safe and efficient flight operations.


The Reversion Switch Panel (RSP) is a crucial component of aviation systems, offering pilots the ability to switch between different modes and configurations. With its control and reversionary capabilities, the RSP provides redundancy, adaptability, and emergency response functionality. Understanding the significance of the RSP in aviation highlights its importance in ensuring safe and efficient flight operations. Pilots rely on the RSP to maintain control and navigate through various flight conditions, making it an indispensable tool in the cockpit.
