Which acronym stands for Inoperative?

• A. IOE
• B. LAV
• C. INOP
• D. MAX

Answer: (C)

Understanding common maintenance shorthand is essential. INOP is the standard abbreviation used on logs and checklists to indicate that a component or system is not operating. That direct meaning is why it’s the best pick here—it clearly communicates the status of “inoperative.” The other options don’t convey that status. IOE isn’t used to mean inoperative (it’s more often seen as Initial Operating Experience or similar terms in different contexts). LAV is commonly short for lavatory, and MAX is used for maximum or can refer to a specific model, not the operational status of a part. So INOP is the clear, correct acronym for inoperative.
