NEW APPLICATIONS: Air Force demonstrates new avionics information system

Air Force Avionics Laboratory engineers have begun demonstrating the Digital Avionics Information System, which could revolutionize aircraft avionics and cockpit displays.

The initial demonstration of DAIS, called mission alpha, is the first of four close air support demonstrations at Ohio's Wright-Patterson AFB scheduled between now and 1980. This marks the first time that DAIS hardware and software have been totally integrated, permitting a laboratory "pilot" to perform all cockpit functions.

Functional capabilities include preflight systems checkout, take-off and climb, cruise, navigation, management of aircraft weapon systems, weapon de ivery, and precision approach and landing.

Mission alpha is "flown" from a simulator that resembles a single seat, fighter/ attack aircraft cockpit. The DAIS concept, however, is applicable to all types of aircraft including cargo transports and bombers. The simulation models reside in a DEC-10 and consist of sensor simulation, earth, atmosphere, ground, and airplane models. No real sensors are used in the demonstration.

According to program manager Lt. Col. Robert A. Dessert, "We haven't found a mission yet that is outside the system's capabilities. In fact, DAIS is functioning so well that we feel it is 'living proof' of all the innovative thinking and design that has gone into the program since we started it in the mid-1960's."

The system includes four core elements: processors or minicomputers, multiplex hardware, computer programs, and control and display systems. The processors are general- purpose digital computers that are specially engineered for airborne use. The multiplex hardware provides standardized information transfer between the other core elements of DAIS. Programs have a modular form to allow easy mission-to- mission sensor or weapon changes, to provide flexibility for major modifications, and to permit transfer of parts of the software to other aircraft applications.

The DAIS controls and displays include five miniature CRTs. One tube functions as a vertical situation display for aircraft attitude control data, one as a head-up display, two as multi-purpose displays for weapon sensor s...
