In various embodiments, the control system includes a first bus extending between a control module of the rescue hoist and a control input device; a second bus extending between the control module of the rescue hoist and the control input device; and a hardwire extending between the control module of the rescue hoist and the control input device.

A light aerial vehicle laminated glazing includes a structural transparent plastic sheet covering the whole of the surface of the glazing, a protective transparent plastic sheet covering the whole of the surface of the glazing, an interlayer adhesive bonding the structural and protective sheets, a glass covered with a conductive layer having a heating function incorporated within the adhesive and covering a fraction of the surface of the glazing at most equal to 66% containing the main viewing zone.

A cooling duct configured to introduce air flow to a cooling target device provided in a helicopter body of a helicopter includes a duct body, a front opening, an upper opening, a hinge, and a movable blade. The duct body is mountable below a main rotor of the helicopter to be adjacent to the cooling target device. The front opening is formed on a forward side of the helicopter body in the duct body. The upper opening is formed on an upper side of the helicopter body in the duct body. The hinge is disposed in an upper portion of the duct body and includes a pivot shaft extending in a lateral direction of the helicopter body. The movable blade with an end that is pivotally supported by the hinge is provided to be pivotable about the pivot shaft between a first position and a second position.
