In flight operation status markings, what does the ⊗ symbol indicate compared to the X symbol?

• A. It grounds the aircraft completely
• B. It places a restriction during flight
• C. It indicates a minor fault
• D. It is used for future maintenance only

Answer: (B)

Flight operation status markings tell the crew what can be done during flight. The circled cross symbol indicates that there are in-flight restrictions—the aircraft is allowed to fly, but with specific limits on systems or performance that must be followed. It’s a permission to operate under certain conditions, not a complete grounding. In contrast, the X symbol represents a total prohibition of air operations until the issue is addressed. So the circled cross is best understood as a restriction during flight. The other options don’t fit because this symbol does not mean grounding the aircraft, nor does it signify a minor fault or that the issue is only for future maintenance.
