What does the throttle control in a basic training airplane?

It regulates airflow and fuel flow to control engine power.

  1. Wing flaps
  2. Engine power ✔
  3. The rudder

Why: Moving the throttle changes how much fuel-air mixture enters the engine. More mixture usually allows the engine to produce more power.

Huh, didn't know that: In many training airplanes, pushing the throttle forward increases power.

The dad joke
The throttle likes to be in control, but only of the engine.

    In airplanes, the throttle is hand-operated and it controls engine speed by regulating the amount of air and fuel that flows into it during the “intake,” or suction phase.
