This course explains how a propeller converts engine torque into thrust, examining tractor, pusher, and push-pull configurations. It introduces the key aerodynamic principles—lift, drag, blade twist, pitch, and efficiency—and shows how blade angle, advance ratio, and tip speed influence performance.

The course also addresses engine failure scenarios, including feathering, and their effects on thrust, drag, and aircraft control. Secondary factors such as torque, gyroscopic precession, P-factor, and the concept of the critical engine are explained in practical terms. Finally, the course provides guidance on go-around procedures and single-engine operations to support safe and effective flight.
