What does having "NC" before a fuel listing indicate regarding contract status with CNATRA?

Having "NC" before a fuel listing indicates that there is no contract established for that particular fuel type with the Chief of Naval Air Training (CNATRA). This status is critical in the operational context as it informs users that fuel may not be readily accessible or may require special procurement processes. By designating a fuel listing with "NC," it clarifies that entities relying on this information should not assume they can procure the fuel in question through standard agreements and may need to explore alternative arrangements or sources. This understanding is key for planning and operational readiness within aviation logistics.
