avionics
Aircraft electronic systems
Avionics is the electronic systems used in aircraft and spacecraft—navigation, communication, flight control, radar, and instrumentation.
The term blends aviation and electronics.
Modern aircraft depend heavily on avionics for everything from autopilot to collision avoidance: The pilot reported an avionics malfunction.
