Course: Aircraft Pilot Training I (20053-I) > Section: Examining Aircraft Instruments, Components, Systems, and Performance

Explanation should include the following:

- An aircraft engine, or powerplant, produces thrust to propel an aircraft.
- Reciprocating engines and turboprop engines work in combination with a propeller to produce thrust.
- Turbojet and turbofan engines produce thrust by increasing the velocity of air flowing through the engine.
- All of these powerplants also drive the various systems that support the operation of an aircraft.
