What documents are required to be carried aboard each domestic air carrier flight conducted under C.F.R. Part 121?

The requirement for carrying specific documents aboard each domestic air carrier flight conducted under C.F.R. Part 121 includes essential items that ensure safety, compliance, and operational efficiency. The dispatch release contains critical information about the flight, including the route, weather conditions, and any regulatory compliance notes. The load manifest outlines the distribution of weight on the aircraft, which is crucial for balance and performance during the flight. Finally, the flight plans provide the necessary routing and operational parameters that air traffic control uses to safely manage the aircraft in the airspace.

These documents help ensure that the flight is properly prepared and adhere to safety protocols, making them indispensable for operations under C.F.R. Part 121. Other options may imply important documents but do not encompass the complete set required for safe and compliant domestic operations as outlined in federal regulations.
