METHOD AND SYSTEM FOR MANAGING AIRCRAFT THREAT DATA

摘要

A method for calculating intervisibility data in advance of its use for permitting a real time update of threat information. Threat intervisibility data corresponding to an area comprised of adjacent regions is calculated and stored. A region of concern is centered in the adjacent regions. As the location of an aircraft changes, threats move from an adjacent region to the region of concern. However, since the intervisibility data was calculated when the threat first appeared in the adjacent region, it is now available for other functions without further processing. Such other functions include providing it to a threat avoidance algorithms or for display within the aircraft.
