Which status symbol is appropriate for an inoperable landing light and aircraft restricted from night operations?

• A. Circled ⊗ status symbol
• B. Circled X
• C. Red flag
• D. Yellow circle

Answer: (A)

When a part is not working and that condition affects how the aircraft can be used, maintenance status symbols convey both the fault and any flight limitations. An inoperative landing light directly impacts night operations, so the symbol chosen should clearly indicate not only unserviceability but also the tied operational restriction. The circled ⊗ symbol is used to mark equipment as unserviceable and to impose related flight restrictions, such as prohibiting night operations until the item is repaired. This makes it the most precise choice for signaling that the aircraft cannot be flown at night because the landing light is inoperative. The other symbols convey different meanings—red flag denotes an immediate safety hazard, a yellow circle implies caution or a temporary condition, and circled X signals “do not use” in some contexts but doesn’t specifically capture the night-operation restriction in this scenario.
