Which statement about the X symbol is true in maintenance status?

Which statement about the X symbol is true in maintenance status?

• A. ⊗ indicates restriction during flight; X grounds completely
• B. ⊗ grounds completely; X restricts flight
• C. Both indicate flight restrictions
• D. They have no relation

Answer: (A)

Flight status indicators communicate different levels of operability. The symbol ⊗ is used to mark a restriction for flight operations, meaning the item may be used on the ground but cannot be flown due to the issue. The X symbol signals complete grounding—no flight activities allowed until the problem is fixed. This distinction makes the statement true: ⊗ indicates restriction during flight, and X grounds completely. The other interpretations would misstate the meaning of one or both symbols.
