What is the maximum permissible static RPM for the L model of a 1974 Cessna 150 in utility and acrobatic categories?

The maximum permissible static RPM for the L model of a 1974 Cessna 150 in utility and acrobatic categories is indeed specified as not over 2560 RPM and not under 2460 RPM. This specification is critical as it ensures that the engine operates within safe limits, providing the reliability and performance necessary for both utility and acrobatic flight operations.

In this case, the cited RPM range is based on the aircraft’s original type certification and operational parameters outlined by the manufacturer. Maintaining RPM levels within this prescribed limit helps to prevent engine damage or failure which could occur from operating outside of these guidelines, especially during demanding maneuvers or when the aircraft is heavily loaded in the utility category.

The other options, while close, do not align with the established operational limits for this model and year, making them incorrect for compliance and safety within the aviation standards outlined for this aircraft type.
