Title: Describe the operation of a propeller.
Course: Aircraft Pilot Training I (20053-I) > Section: Explaining the Aerodynamics of Flight

Description should include the following concepts:

- The propeller is a rotating airfoil, subject to aerodynamic principles that apply to any airfoil such as induced drag and stalls.
- The propeller provides the necessary thrust to pull or push the aircraft through the air.
- The propeller itself is twisted, so the blade angle changes from hub to tip. The greatest angle of incidence or the highest pitch is at the hub, while the smallest angle of incidence or smallest pitch is at the tip.
