Paper Abstract
The increasing use of IR pilot sight in helicopters calls for a reliable prediction of perception ranges for a variety of
objects, especially those needed for orientation and those posing as a potential hazard, like power poles, masts, isolated
trees etc. Since the visibility of objects in the IR depends mainly on the temperature differences between those objects
and a given background and only marginally on illumination, range prediction techniques used for the visual range or
light-amplified vision are only of very limited use. While range predictions based on the Johnson criterion do offer some
insight into expected ranges, the inherently nominal nature of distance estimates thus obtained hampers their use for an
actual field-deployable pre-flight consulting procedure. In order to overcome those limitations, long-term simultaneous
measurements of relevant objects and background temperatures and weather data were carried out and used for
temperature prediction from prevalent weather conditions. Together with a perception model derived from extensive
observer experiments based on synthetic images of the UH Tiger Pilot Sight Unit we developed a perception range
prediction package which is currently evaluated by the weather service of the Bundeswehr. We will present results from
the observer experiments together with the derived perception models. These are then compared to actual perception
ranges as obtained from flight experiments.
