The Boeing Joint Helmet Mounted Cueing System (JHMCS) combines a magnetic head tracker with a display projected onto the pilot's visor, giving the pilot a targeting device that can be used to aim sensors and weapons wherever the pilot is looking. With JHMCS, the pilot can aim the radar, air-to-air missiles, infrared sensors and air-to-ground weapons merely by observing the target through the helmet's visor and pressing a switch on the flight controls. Additionally, the pilot can view any desired data (airspeed, altitude, target range, etc.) while "heads-up," eliminating the need to look into the cockpit during visual air combat.
