Improvement of tactical situation awareness with colour-coded horizontal-situation displays in combat aircraft

摘要

In the multi-role combat aircraft Gripen, the monochrome head-down displays in the cockpit are to be upgraded in colour. In the present study, the effects of colour-coded displays on visual search and situation awareness(SA)were studied in a real-time simulation of an air-to-air mission with test pilots as subjects. Gripen's monochrome colour scheme was compared to two chromatic (dichrome, polychrome)colour schemes. A 3×2×2 factorial within subjects design was used; the three colour schemes each with two different background conditions(simple and complex)and two different symbol configurations.
