In aviation terminology, "cast off" refers to the action of letting go, throwing off, or unfurling something. This term is frequently used in the context of marine operations and is also applicable to aviation when referring to the release of lines, tethers, or other items that may be securing an aircraft, particularly during pre-flight preparations. At times, it can also describe the action of releasing a towline, which facilitates the aircraft's release from the tug during a tow operation.

This definition highlights the importance of ensuring that an aircraft is free to move before takeoff, allowing for a smooth and safe operation. The other concepts, such as commands to start the engine, safety procedures before takeoff, or a type of navigation maneuver, do not encapsulate the precise nature of "cast off" as it pertains specifically to releasing or letting go of something. Understanding this term within the operational context is essential for pilots and crew members to ensure thorough pre-flight checks and safe takeoffs.
