Many air defense AD systems use geometric symbols to indicate aircraft on system displays and different shapes to encode friend-or-foe information. The purpose of the ARIs AD symbology research was to identify sets of geometric symbols associated with high discriminability and quick response times. This paper deals with Phase 3, in which the symbol sets were presented upon cathode ray tube CRT display. Symbol shape was the independent variable RT and errors were the dependent variables. The hypotheses were that some sets would have lower RTs and errors, and that the results of Phases 2 and 3 would agree.
