Wind Factor Simulation Model: User's Manual.

Abstract

User instructions and a concise description are provided for a Wind Factor Simulation Model (WFSM). The WFSM is a fast, economical module designed to reside as a collection of subroutines within the user's larger simulation model. The WFSM, upon call by the user, produces mean overall climatological wind factors for great circle routes between arbitrary points 'A' and 'B' (specified by latitude and longitude) anywhere on the globe. The WFSM produces wind factors in any of three modes (calm wind case, 90-percent worst case, and the mean wind case), for either of two altitudes (25,000 ft and 35,000 ft) for any of four seasons of the year. In addition, the model can provide great circle distance between points 'A' and 'B.' From this information and known airspeed, the user can calculate ground speed and adjusted flying time between 'A' and 'B.' Software solves the equation of a great circle. Program listing and flow chart are included. (Author)
