This is a list of the commonly used avionics and light panels supplied by the aircraft. For realistic simulation, avionics and lighting should be powered with the appropriate bus. ProSim avionics allows you to access the bus gates for switching under the Combined Config – Electric menu. Jeehell FMGS avionics allows bus gate switching in their API and hardware (relays) by Cockpit Concept.
