This topic has come up from time to time. To further this discussion I am attaching excerpts from two references. First, AFM 64-5, "Survival." This manual contains a nomogram for this determination. Second, excerpts from Gatty's "Raft Book." There is a detailed table on the back of his world map for this computation. There are also instructions for making a "harp" to use in measuring altitudes. Both of these books also contain methods for determining longitude by timing sunrise. My prior post included files that are quite large, I found our how shrink them down and here are the condensed versions. gl -- NavList message boards: www.fer3.com/arc Or post by email to: NavList@fer3.com To , email NavList+@fer3.com
