What is Loiter?

In aeronautics and aviation, loiter is the phase of flight consisting of flying over some small region.
In general aviation, the loiter phase generally occurs at the end of the flight, when the plane is waiting for clearance to land. In military flights, such as aerial reconnaissance or ground-attack aircraft, the loiter phase is the time that the aircraft has over a target. Cruise is the time period the aircraft travels to the target and returns after the loiter.
