Title: Describe fixed-pitch propellers.
Course: Aircraft Pilot Training I (20053-I) > Section: Understanding Aircraft Systems: Propellers, Landing Gear, and Brakes

Description should include the following concepts:

- A propeller with fixed blade angles is a fixed-pitch propeller.
- The pitch of the propeller is set by the manufacturer and cannot be changed.
- Since a fixed-pitch propeller achieves the best efficiency only at a given combination of airspeed and rpm, the pitch setting can be optimized for either cruise or climb, but not both.
- The fixed pitch propeller is used when low weight, simplicity, and low cost are needed.
