What is the primary function of a pusher propeller in an aircraft?

1. To pull the aircraft forward

2. To enhance stability during flight

3. To push the aircraft from the rear

4. To reduce drag during landing

The correct answer is: To push the aircraft from the rear

The primary function of a pusher propeller in an aircraft is to push the aircraft from the rear. This configuration differs from a puller propeller, which is located at the front of the aircraft and pulls it forward. Pusher propellers can improve aerodynamic efficiency in certain designs and provide clearance for the wings and fuselage, making them particularly useful for aircraft with unique aerodynamic needs or those that require engines to be positioned at the rear. This design can also contribute to better visibility from the cockpit, as well as the potential for quieter cabin conditions since the noise from the propeller is located behind the aircraft.
