Requirements of JTCG/AS test and evaluation resulted in AV (vulnerable area) data being developed for only six cardinal views. These views are defined using the positive and negative directions along the axes through the aircraft centroid. Six views are insufficient for attrition modeling purposes. For example, P001 required 26 views which must be obtained by projection of the six cardinal views. This can be accomplished using either an R(rectangular) or E (ellipsodial) projection technique. To determine the better technique, Raytheon was tasked to evaluate the relative merits of the two techniques. The scope was later expanded to include an examination of the Ap (presented area) computation techniques used in the P001, SIMFIND 2, and EVADE II attrition models.
