Overview
The function of the lights is to supply light to internal and external areas and components of the aircraft. The lighting is an aid to the flight crew, passengers, airport personnel and maintenance personnel for their work and safety.
The lights system components operate independently of each other. Different DC-busses, AC-busses and battery busses of the aircraft supply power to the lights system. When power is not available, internal batteries supply power to some of the lights systems.
The lighting system includes:
- Flight Compartment Lighting
- Passenger Compartment Lighting
- Service Compartment Lighting
- Exterior Lighting
- Emergency Lighting
