Tailout

Tailout is a term used in various fields, including computer networking, photography, and navigation. In general, it refers to the process or act of gradually winding or withdrawing something, often to a final point of termination or conclusion.

In computer networking, tailout is a function or procedure used to gradually transmit packets of data to the end of a communication session. The term is often associated with asynchronous transfer mode (ATM) and Frame Relay protocols. Tailout is used to prevent buffer overflows and ensure smooth data transfer.

In photography, tailout refers to the last part of a photographic exposure, especially during long time exposures. It may also refer to the final stages of developing a photographic image.

In navigation, particularly in aviation and maritime contexts, tailout can refer to the last part of the flight plan, trajectory, or course correction leading to a desired destination or termination point.

In rocketry and space exploration, tailout is the period of time during a rocket's launch phase, immediately preceding the nose-first alignment of the rocket's main stage with the ground. This is often followed by the regression of the rocket, where the nosecone becomes level with the nearly spent first-stage rocket body.

The term tailout originates from the idea of a whip or cord being slowly drawn out or unwound. In various contexts, tailout is used to indicate a gradual or final process of termination, cessation, or withdrawal.
