What call is made to discontinue maneuvering when safety of flight is not a factor?

The call made to discontinue maneuvering when safety of flight is not a factor is "Terminate." This term is typically used in aviation and military contexts to indicate that an exercise, maneuver, or training session should be stopped without any immediate safety concerns. "Terminate" signals to all involved that the current activity is to be concluded effectively, allowing for a smooth transition to whatever comes next without implying any urgency or safety issues.

While "Abort" is used in situations where immediate safety is a concern and action must be taken to prevent hazardous conditions, and "Knock it off" is employed to halt training or operations due to safety concerns, "Terminate" applies in scenarios where the maneuvers can be concluded safely without those pressures. "Cancel," while similar, does not specifically relate to the context of maneuvering in flight operations. Thus, "Terminate" is the most appropriate term for signaling the end of a maneuver when safety is not an issue.
