Why is a club propeller used when test running an overhauled engine?

For aesthetic purposes
To reduce weight
For proper cooling and correct load
To improve flight characteristics

The correct answer is: For proper cooling and correct load

A club propeller is utilized during the test running of an overhauled engine primarily to ensure proper cooling and to provide the correct load on the engine. When an engine is tested, it is essential to simulate operational conditions that closely represent its performance during flight. The design of a club propeller allows for adequate airflow over the engine, which is critical for cooling. Furthermore, the club propeller can help simulate a representative load on the engine, enabling technicians to observe how the engine performs under conditions similar to those it will experience in service. This is vital for diagnosing any potential issues and ensuring that the engine operates efficiently and reliably once installed on an aircraft. The other choices do not directly relate to the technical requirements of testing an engine after an overhaul.
