horizontal situation display การใช้

The horizontal situation display was prone to frequent failures, delivery of field ground equipment was late, and depot support was poor.
The company entered into a contract to provide the Horizontal Situation Display ( HSD ) for the Air Force F-111 Aircraft . This display program, which combined CRT and optical technologies, resulted in further expansion of Astronautics Engineering, Quality, Reliability, Production and Contract Administration Departments.
There is evidence that the term Situational Awareness was first employed at the Douglas Aircraft Company during Human Factors Engineering research while developing vertical and horizontal situation displays and evaluating digital-control placement for the next generation of commercial aircraft . Research programs in Flight-Crew Computer Interaction and Mental Workload Measurement built on the concept of awareness measurement from a series of experiments that measured contingency awareness during learning and then later to mental workload and fatigue.
