Collective Control System

Drawing: Collective control head

The pilot and gunner collective pitch controls are located on the left side of the pilot and gunner seats and control vertical mode of flight. Moving the stick up or down changes the angle of attack and lift developed by the main rotor resulting in the ascent or descent of the helicopter. The collective assembly consists of a collective stick, with adjustable friction system (pilot only), twist grip-type throttle with friction adjuster, and switch box assembly (pilot only). The switch box assembly incorporates the ignition starter switch, rpm increase-decrease switch, jettison, searchlight switches, wire cut switch, and idle stop release switch. A collective hold down strap is provided for the pilot collective.
