Which system is dedicated to managing electrical power distribution to avionics and lighting?

• A. Landing Gear System
• B. Electrical System
• C. Fuel System
• D. Ice Protection System

Answer: (B)

Power to avionics and lighting is managed by the electrical system. This system combines generators or alternators, the aircraft battery, and the wiring with buses and protection devices that route and safeguard electrical power to different loads. Avionics and cockpit lighting are connected to essential or specific electrical buses so they receive reliable power even if other systems are shedding load, and through circuit breakers and distribution rules the power is allocated where needed. The other systems serve different roles—landing gear handles gear extension and retraction, fuel system manages storage and delivery of fuel, and ice protection uses de-icing methods—so they aren’t responsible for distributing electrical power to avionics and lighting.
