What does DD Form 365-1 specifically inventory?

The DD Form 365-1 is specifically used to inventory the operating equipment on board an aircraft. This form is essential for maintaining the safety and operational readiness of the aircraft, as it ensures that all necessary equipment, such as survival gear, oxygen systems, fire extinguishers, and other critical items, are accounted for before flight. By maintaining a detailed inventory of these items, aircrew can ensure both compliance with regulations and readiness for any operational requirements.

The emphasis on operating equipment highlights its role in mission success and safety, as missing or malfunctioning equipment can significantly impact flight operations. Proper inventory helps mitigate risks and prepares the crew for diverse scenarios that may arise during flight. Other options like fuel levels, maintenance supplies, and flight crew equipment are also important, but they do not fall under the specific purpose of the DD Form 365-1.
