FAAC’s Zone Acquisition Process (ZAP) provides high-speed missile simulations capable of running much faster than real-time with limited resources. ZAP was initially developed in the late 1970’s as part of the Air Force MISVAL program designed to improve the missile launch envelope (MLE) information presented to F-15 and F-16 pilots. ZAP was the first program to successfully embed high-fidelity missile fly-out simulations in the on-board computer used for determining weapon employment zone parameters in real-time. ZAP improved the inherent accuracy of the information presented by more than 50%. In addition, ZAP enabled new information to be presented to the pilot relating to shot quality, post launch missile status, and the effects of target maneuvers.
FAAC has formally integrated ZAP into the production F-15 Operational Flight Program. Using a Launch Zone Interface Working Group (consisting of aircrew, weapon manufacturers, The Boeing Company, and FAAC representatives) the entire weapon employment display concept was reviewed and replaced based upon the enabling ZAP technology. ZAP now provides the information to support Air-to-Air and Air-to-Ground weapon employment displays. ZAP relies on faster-than-real-time 5-DOF trajectory simulations to determine missile parameters. These simulations typically complete a full fly out on a single processor of the F-15 Central Computer. The ZAP trajectory simulations match the engineering 6-DOF reference simulations. This results in highly accurate display information over the entire flight envelope. ZAP provides reliable shoot cue information and allows a meaningful allowable steering error to be displayed. After launch, ZAP computes the current time to impact using actual tracked target maneuvers and continually assesses the shot quality and provides indication of predicted end game success. ZAP has been well received by the aircrew and is considered to provide a tactical advantage. Current weapons supported by ZAP:
