Which form is required to be accomplished prior to each departure for weight and balance verification?

The requirement for a specific form to be accomplished for weight and balance verification prior to each departure is grounded in ensuring the safety and operational effectiveness of the flight. The correct form is the DD Form 365-4, which is specifically designed for verifying the weight and balance of aircraft before takeoff.

The DD Form 365-4 is utilized to account for the aircraft's current configuration, including the weight of the aircraft, fuel load, and the weight of any passengers and cargo. This provides critical information necessary for flight operations, allowing aircrew to ensure that the aircraft is within safe operating limits, which directly impacts the performance and safety of the flight.

Each of the other forms listed (DD Form 365-1, DD Form 365-2, and DD Form 365-3) serves different purposes within the weight and balance documentation process, but they are not specifically required to be filled out prior to each departure. Understanding the distinction between these forms is essential for aircrew members to maintain compliance with operational standards and safety regulations.
