What Air Force instruction requires your shop to have a budget?

The correct answer is that the instruction requiring a budget for your shop is AFI 11-301V1. This instruction outlines the policies, procedures, and guidelines for the management of aircrew equipment and associated costs, which inherently includes budgeting aspects. It emphasizes the need for financial planning to ensure that aircrew have access to the necessary equipment and resources, aligning with the operational and safety needs of the Air Force.

AFI 11-301V1 also provides accountability measures and responsibilities for managing financial resources effectively, ensuring that all required equipment and maintenance can be funded properly. This makes having a budget essential for operational readiness and compliance with established financial regulations and standards.

In contrast, the other options cover different areas that do not focus specifically on budget requirements for aircrew flight equipment.
