Among the following, which is the designated publication for M-31 reference?

• A. NAVAIR 51-5FAA-1
• B. NAVAIR 52-5FAA-1
• C. NAVAIR 51-5FAA-2
• D. NAVAIR 51-5FAA-3

Answer: (C)

In this context, the standard reference for M-31 is the official designated publication that all training and procedures rely on. NAVAIR 51-5FAA-2 is that designated source, representing the current revision used for M-31 materials. It contains the procedures, data, and charts you’re expected to know in this setting. Editions with -1 or -3 exist, but they aren’t the designated reference for M-31 here, so they aren’t used as the standard for exams or official guidance. In practice, always confirm the current designated publication and revision in your unit’s M-31 reference list, since updates can change what’s considered the official source.
