[QUOTE="BryanLitz, post: 478701, member: 7848"] The Miller stability formula, along with corrections for velocity and atmospherics are in the appendix of my book. If you want a similar formula for calculating trajectories, you're out of luck. The equations of projectile motion must be integrated (solved) numerically, which is an iterative/recursive process best managed by modern computers (the program takes 0.001 second time steps for the whole trajectory). The programs are 100's of lines long, and is not something intended to be done by hand. Once you have the basic trajectory with tof, you can easily figure out spin drift, coreolis, and other effects with the formulas in my book (appendix). However that basic trajectory is a job for a computer. -Bryan [/QUOTE]
