A control system for a rescue hoist attached to an aircraft is disclosed. In various embodiments, the control system includes a first bus extending between a control module of the rescue hoist and a control input device; and a second bus extending between the control module of the rescue hoist and the control input device. The first bus is configured to transmit a first signal from the control input device to the control module and the second bus is configured to transmit a second signal from the control input device to the control module, both the first signal and the second signal being generated by the control input device in response to a manipulation of the control input device.

A payload loading system is disclosed. The payload loading system includes a UAV and a loading structure. A retractable tether is coupled to a payload coupling apparatus at a distal end and the UAV at a proximate end. A payload is loaded to the UAV by coupling the payload to the payload coupling apparatus. The loading structure of the payload loading system includes a landing platform and a tether guide. The tether guide is coupled to the landing platform and directs the tether as the UAV approaches and travels across at least a portion of the landing platform such that the payload coupling apparatus arrives at a target location. The payload is loaded to the payload coupling apparatus while the payload coupling apparatus is within the target location.

A method for passive aerial cord release mechanisms and an aerial cord release mechanism for an aerial vehicle (AV). A method includes determining a retracting force to be applied to a winch of an aerial vehicle (AV), wherein the determined retracting force is a force required to retract a cord to be coiled around the winch within the AV, and the cord is temporarily coupled to the winch, such that an external force exceeding a predetermined threshold causes decoupling between the cord and the winch.

A system for adjusting a load on a tethered aircraft is disclosed. The aircraft is tethered to a payload. The system determines a new position for the tethered aircraft in the event that due to environmental effects, e.g., the aircraft is flying upwind or downwind, the load experienced by the tethered aircraft is not optimal.
