- Office of Primary Responsibility
This Advisory Circular (AC) provides guidance for the submission and approval of special instrument flight procedures developed by non-FAA service providers and submitted to the Federal Aviation Administration (FAA) for review and approval. Special instrument procedures are those procedures developed for specific users and are not processed under Title 14, Code of Federal Regulations (14 CFR), Part 97. Occasionally, the word "must" or similar language is used within this AC where the desired action is deemed critical. The use of such language is not intended to add to, interpret, or relieve a duty imposed by 14 CFR.
