Which code stands for Additional Crew Member?

• A. AC
• B. ACM
• C. AED
• D. AA

Answer: (B)

When forming a code from a phrase, the clearest shorthand is usually the initials of every word in that phrase. For "Additional Crew Member," the natural code uses the three initials A, C, and M, giving ACM. This matches all three words and keeps the meaning concise, which is exactly what a practical staff code should do. The other candidates don’t fit as well: one uses only two initials and would miss the word "Member," while others are standard abbreviations for completely different terms (AED is a defibrillator, AA often stands for Alcoholics Anonymous or American Airlines). So ACM uniquely represents the intended role.
