Electrical power in an aircraft is distributed to avionics and lights via what network?

• A. Hydraulic lines
• B. Bus networks
• C. Fuel lines
• D. Pneumatic ducts

Answer: (B)

Electrical power is sent to aircraft systems through bus networks, which are organized groups of conductors that carry power from sources like generators and batteries to the loads such as avionics and lights. This bus setup lets power be distributed efficiently and protected properly, with separate buses (for example, essential and nonessential) so critical systems stay powered even if some sources falter. Circuit breakers or fuses protect each bus, and the power distribution unit manages which loads get power and when. The other options refer to fluid or air systems—hydraulic lines carry hydraulic fluid, fuel lines carry fuel, and pneumatic ducts carry conditioned air or bleed air—not electrical power.
