For the crew harness, which conditions must be met during pre-flight checks?

• A. Adjusted to fit, in good condition, functions and retracts
• B. Loose and unadjusted
• C. Adjusted to fit only
• D. Not required to check

Answer: (A)

The important idea here is that a crew harness must be checked for fit, condition, and proper operation. During pre-flight checks you want the harness to be adjusted to fit the wearer so it restrains correctly without being too loose or too tight. It also must be in good condition—no frayed straps, damaged buckles, or signs of wear that could fail under load. Finally, the mechanism itself has to work: the buckle must release smoothly, the retractor should take up slack and lock when needed, and the overall system should function as intended. If any of these aspects are missing—if it’s not adjusted to fit, if it’s damaged, or if the operation and retraction don’t work—the harness could fail to provide the necessary restraint in an emergency. That’s why the complete requirement is adjusted to fit, in good condition, and capable of functioning with a working retractor.
