If the enroute supplement shows "NC" before a fuel listing, what does it indicate for CNATRA aircraft use?

The designation "NC" before a fuel listing in the enroute supplement indicates that the fuel is not authorized for use by CNATRA (Chief of Naval Air Training) aircraft. This is crucial for pilots and operators as it helps ensure that the aircraft is fueled with approved sources, allowing for optimal performance, safety, and compliance with operational guidelines.

Understanding the context of this designation is essential for effective flight planning and safety management. Knowing which fuels are authorized (or not authorized) supports adherence to regulations and operational procedures that are vital to the successful execution of missions involving CNATRA aircraft. Consequently, this designation helps prevent the use of potentially unsuitable fuels that could compromise aircraft integrity or safety.
