Abstract :
A description is given of DASH, a display and sight helmet system which measures the pilot´s line of sight and transfers the information to other aircraft systems, thus enabling the pilot to achieve lock-on of sensors, avionics, and weapons onto a target simply by looking at it. Crucial information, such as line of sight, TD boxes, flight information, status, and warnings, is displayed directly in front of the pilot on the helmet visor, eliminating the need to glance inward at the instrument panel or head-up display. With expanded lock-on envelope, shorted aerial engagement, increased survivability, user-friendly display and HOTAS controls, the system proved to be a true revolution in air-to-air and air-to-ground combat. The author gives a technical description of the system, discusses its operational aspects, and addresses future programs and developments
