What must be included on a domestic air carrier dispatch release?

The requirement for a dispatch release for domestic air carriers includes critical operational information essential for flight safety and efficiency. Minimum fuel supply is particularly important as it directly relates to the aircraft's ability to safely complete its intended flight, accounting for potential contingencies such as delays or unexpected weather changes. The trip number is also fundamental as it uniquely identifies the specific flight, enabling accurate tracking and reference throughout the flight planning and operational process.

In contrast, while scheduling evidence, company name, and aircraft identification are pertinent for operational records and identification, they are not specified essential components for the dispatch release itself. Similarly, passenger boarding times and baggage weight, while important for operational planning, do not constitute a mandatory element of the dispatch release. The focus of the dispatch release is on ensuring that the flight has adequate fuel and is correctly identified for safe operation.
