Which system powers the aircraft propulsion?

Which system powers the aircraft propulsion?

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

Answer: (C)

Propulsion is powered by the powerplant, the engine or engines that turn fuel into energy to produce thrust. The powerplant is the energy source that drives the propulsion system, converting the stored fuel into mechanical power that pushes the aircraft forward. The fuel system supports this by delivering fuel to the powerplant, but it does not itself generate thrust. Other systems have different roles: the landing gear system handles wheel deployment and braking, and the ice protection system prevents ice buildup on surfaces. So the powerplant is the only component whose function is to generate the energy that creates propulsion.
