What information is specifically required in the flight release for supplemental air carriers that is not included for flag carriers?

In the context of flight releases for supplemental air carriers, one specific requirement is the inclusion of the names of all crewmembers. This is a notable distinction from flag carriers, which may not require such detailed identification of their entire crew on the flight release documentation. The rationale behind this requirement for supplemental air carriers likely stems from safety and accountability considerations, ensuring that all involved personnel are accounted for and identified, leading to more efficient operational management and compliance with regulatory standards.

The focus on having all crewmember names on the flight release can aid in coordination during pre-flight briefings and in-flight operations, facilitating communication among crew members. This ensures that safety protocols and responsibilities are clearly understood and can reduce the risk of miscommunication or accountability issues during flight operations.

Other options, while relevant to the broader context of flight operations, are either already standard requirements for both types of carriers or not specifically mandated only for supplemental air carriers. For instance, weather reports and forecasts, minimum fuel supply, and flight routes and destinations are critical pieces of information for all types of operations and are generally expected to be part of the flight release process across the board, rather than being exclusive to supplemental operations.
