What is the primary function of the Avionics Master Switch?

The primary function of the Avionics Master Switch is to power all avionics and radio systems in an aircraft. This switch is crucial for the operation of a variety of electronic instruments required for navigation, communication, and monitoring of the aircraft systems. When the Avionics Master Switch is engaged, it allows the necessary electrical power to flow to these systems, enabling pilots to access important flight data, communicate with air traffic control, and ensure the overall functionality of aircraft instruments. It is a fundamental component in maintaining operational readiness for all electronic systems that are vital for flight safety and efficiency.
