Devices for estimating the range to a simulated pyrotechnic flare were evaluated against several unaided conditions. Two devices based on a photometric concept and two based on a geometric concept were used. One was a human-engineered triangulation device (Ritchie Ranger modified). The errors of naked eye judgments are discussed. Also discussed are technological requirements for operational ranging devices and future plans for an inflight evaluation of methods for flare range estimation. (Author)
