INOP stands for which term?

• A. Inoperable
• B. Inactive
• C. In-Operation
• D. Inoperative

Answer: (D)

INOP is used in aviation to indicate that an item is not functioning at the moment. It stands for Inoperative, a status tag crews and maintenance use to quickly communicate that a system or piece of equipment cannot be relied upon until it’s repaired or deemed operable again. This is why Inoperative is the best choice here: it directly matches the meaning of the abbreviation as a current nonfunction, rather than describing a general inability to operate (which “inoperable” implies) or states like “inactive” or “in-operation,” which aren’t the standard status used with this tag. So when you see INOP, you treat the item as nonfunctional and follow the appropriate MEL/repair procedures before using it.
