Algebraic Firing Solution

[Dorjun Driver]

I disagree that the Lead angle is all you need. I consider the other elements, Track Range, Run Time, and Time to Position to be of almost equal importance.

I did see your posting on zero-gyro shooting. Did you see the formulas in the OP? The first one in particular will give you equivalent results.

[I restored the images in the OP. I had reorganized them at Photobucket and broke the links. Sorry!]

I didn’t make myself clear. What I meant is that when the target takes an unexpected zig or zag at the last moment, given she maintains her speed, all that’s required is to plug in the new intercept angle given her new course. From that—and maybe a little stick and rudder work—the deflection/lead angle then drops into your lap. With seconds to spare, too!

As you may have gathered, human factors aren't my strong suit.
