In what form must the flight release specify an alternate airport?

The flight release must specify an alternate airport through formal documentation to ensure compliance with regulations and enhance operational safety. This formal documentation typically includes details in the flight plan or release itself, which serves as an official record for the flight operations team, as well as for any oversight authorities. Specifying an alternate airport in this manner ensures that all parties involved in the operation are aware of a safety plan should landing at the intended destination become impractical, thereby promoting a standardized procedure.

Formal documentation is crucial for various reasons, including accountability, clarity of communication, and adherence to aviation regulations set by governing bodies. It guarantees that the provided information is verifiable and can be referenced if needed. This is particularly important when changes in weather or other conditions dictate an alternate landing location, as all personnel will rely on the documented procedure to maintain safety and efficiency in operations.
