I2.4 - Perception Range Prediction for IR Pilot Sight

Robert Weiss
The new helicopters of the Bundeswehr, the UH Tiger and the NH-90, are equipped with a far-infrared Pilot Sight Unit (PSU). This sensor is used for both navigation and obstacle avoidance. At the beginning of our project, there was no established procedure to predict the IR viewing range under given weather conditions. Aviation safety guidelines, however, require a pre-flight assessment of prevalent viewing conditions for a given sensor. A high priority project was started by...
