Abstract
A hoisting system for hoisting a load relative to a body includes a hoisting cable, a hoisting mechanism selectively operable to deploy and retract the hoisting cable, and a guide mechanism movably mounted to the body at a position between the body and the hoisting cable. The guide mechanism includes at least one locking device that selectively locks the guide mechanism against movement in a first direction.

An aircraft comprising:
- an airframe having an opening in communication with a cabin;
- a hoisting system for hoisting a load relative to the airframe, the hoisting system including:
- a hoisting cable;
- a hoisting mechanism mounted to an exterior of the airframe selectively operable to deploy and retract the hoisting cable;
- a guide mechanism mounted to the exterior of the airframe directly underneath the opening, the guide mechanism being located remote from the hoisting mechanism and being rotatable about an axis relative to the airframe;
- and
- at least one locking device operably coupled to the guide mechanism, wherein the at least one locking device locks rotation of the guide mechanism about the axis in a first direction.
