What is a characteristic feature of the C-172 propeller?

The Cessna 172 is equipped with a fixed-pitch propeller, which is designed to provide a consistent angle of attack that optimizes performance for cruising speeds. A characteristic feature of the Cessna 172's propeller is that it typically has two twisted blades. This design helps ensure that the lift generated across each blade is more uniform, which results in more equal thrust production. The twisting helps manage the angle of attack as the blade rotates, allowing for improved aerodynamic efficiency.

This design helps mitigate performance issues and contributes to a balance of power and efficiency during various flight conditions. In contrast, options involving variable pitch or three-blade configurations do not typically apply to the standard C-172, as it does not utilize those advanced technologies or designs mainly found in more complex aircraft. Additionally, carbon composite materials are generally used in some advanced propeller designs but are not synonymous with the traditional construction materials used for the Cessna 172's propeller.
