What are the references for the ACS?

• A. The ACS are based on 14 CFR parts, FAA guidance documents, manufacturer's publications, and other relevant documents.
• B. The ACS are based only on company manuals.
• C. The ACS references include international regulations only.
• D. The ACS references rely solely on pilot testimonials.

Answer: (A)

The main concept is that the ACS references come from official regulatory and FAA guidance sources, not from isolated or informal materials. The ACS are built on 14 CFR parts, FAA guidance documents, manufacturers’ publications, and other relevant documents. This mix ensures the standards reflect federal regulations, FAA interpretations, and how aircraft systems and procedures actually work in practice. Manufacturer publications provide specifics about the aircraft you’ll train and test in, while FAA guidance documents help interpret how those regs apply to practical flight tasks. The “other relevant documents” catch-all brings in advisory circulars, service bulletins, and related FAA or industry materials to keep the standards current and comprehensive.

Relying only on company manuals would miss the regulatory requirements and official FAA expectations. Relying solely on international regulations wouldn’t cover U.S.-specific certification standards. Relying on pilot testimonials wouldn’t provide the objective, verifiable basis these standards require.
