Abstract

This paper presents results obtained during a flight evaluation of Night Vision Devices (NVDs) equipped with a symbology injection capability. The NVDs used represented both conventional and wide (Panoramic) Field of View Night Vision Goggle (PNVG) systems. The evaluation was conducted at the National Research Council of Canada Bell 205 Flying Simulator under the auspices of the Technical Co-operation Programme. 6 Pilots from 4 nations participated in the trial and some 36 hours of flight data and pilot performance were recorded. The metrics used to evaluate Pilot performance included conventional Visual Cue Ratings, estimates of workload, and objective measures obtained through advanced data-analysis techniques. The trial used both conventional ADS-33D manoeuvres and a novel 'Racetrack’ course. The paper concludes that although PNVG compare favourably with NVGs the clarity of image currently available in standard NVGs surpasses that of the PNVG and negates some of the advantages gained by the wider Field of View. The manoeuvres favoured by the NVG include those where a high degree of foveal attention demanding processing is being performed, for example navigation tasks. The manoeuvres favoured by the PNVG include those where a more automatic peripheral processing is being performed, for example in reducing drift in the hover.
