In order for a new safety belt installed on an aircraft to meet compliance, it must conform to the requirements in which document?

The correct answer is TSO C22 because this document specifically outlines the standards and requirements for safety belts and harnesses used in aircraft. Technical Standard Order (TSO) C22 sets forth the minimum performance standards that safety belts must meet to ensure their effectiveness in protecting occupants during flight. Compliance with TSO C22 is crucial for ensuring that any safety equipment installed in the aircraft meets the necessary safety benchmarks set by aviation authorities.

Additionally, while the other options may pertain to aviation safety in a more general sense, they do not provide the specific performance criteria for safety belts. TSA regulations focus more on security measures rather than equipment standards, the FAA Flight Safety Manual includes broader operational safety guidance, and Maintenance and Safety Guidelines cover maintenance procedures but do not specifically address the certification and performance of safety belts. Thus, TSO C22 is the definitive standard for ensuring compliance in safety belt installations on aircraft.
