Which status symbol indicates a deficiency that may be operated under set limitations?

• A. X status symbol
• B. Diagonal Slash
• C. Circled X status symbol
• D. Horizontal Dash

Answer: (C)

In maintenance status communication, a circled X shows a deficiency that can be operated under set limitations. It signals that the item isn’t fully serviceable, but you may use it within prescribed restrictions until repairs are completed. The circle around the X communicates that use is allowed, but with caution and specific limits outlined in the maintenance directives or operator’s manual.

For example, a vehicle with a minor hydraulic leak might be allowed to operate for limited test or training purposes, with restrictions on speed, load, or mission type. The goal is to keep the asset usable where safe and practical while ensuring the defect is corrected.

Other marks indicate more severe states—either no use at all or a different condition—so they don’t convey the same restricted-use meaning as the circled X.
