Title: Explain how thrust is produced in both the fixed-pitch and constant-speed aircraft propellers and how RPM is registered on the tachometer.
Course: Aviation Maintenance Technology I (20114-I) > Section: Maintaining the Power Plant

Explanation should include the following:

- Thrust is produced by the propeller rotating and pulling air through it, forcing it rearward, causing the aircraft to move forward.
- Fixed-pitch propellers adjust their RPM to gain thrust.
- Constant-speed propellers change their blade pitch to increase thrust.

Process/Skill Questions:

- How does a fixed pitched propeller gain thrust?
- What is thrust?
