Utvaedering av en Temporal Hotindikator (Experimental Evaluation of a Temporal Display).

摘要

The purpose of the present experiment was to evaluate the feasibility of a so called temporal display, presenting time intervals for weapon emission or evasive action. A BVR air combat was simulated. Two professional fighter pilots were used as subjects. Two conditions for presentation of tactical information were compared. In one of them a conventional TSD and a multisensor display were used. In a second condition the above mentioned temporal display was presented in addition to the other two. Objective performance (no. of weapon emissions, no. of hits) was recorded. The subjects also made subjective ratings of e.g. workload (WL) and situation awareness (SA). They answered queries in written and oral form. Precision (i.e. no. of hits/no. of emissions) was found to be significantly higher when the temporal display was available. However, the subjective ratings of WL and SA were not affected by the presentation of the temporal display. The subjects raised objections to the color coding, size of symbols, and size of display area. The displays have only been tested in generic cockpit environments. Performance figures in the simulation can not be compared to performance figures of any specific aircraft.
