Re: Ballistics calculation
Gotta be more specific. What kind of ap are ya runnin?
The programs I've dealt with for ballistics ask and compute for a direction relative to a 12 hour clock, with 12 being a wind straight toward you from the target. 3 and 9 are true 90 degree crosswinds, 6 is a true tailwind, blowing from you toward the target, ect.
Angle of wind can mean alot of things.............a true crosswind would normally be thought of as from 3 O'clock or 9 O'clock.........or 90 degrees relative to line of sight.
However, winds from different angles are where the confusion comes in.
I deal with angles and angles relative to other angles all day at work, lots of trigonometry in what I do. Heres what I am getting at.....
Example: A wind from 11 O'clock (30 degrees left of straight in your face) could be considered a 30 degree wind, or a 60 degree wind (60 degrees from a true crosswind) or a 330 degree wind (relative to azimuth, with 0 or 360 being true downrange), possibly even a negative or -30 degrees..............just depends on how the ap is configured for that input/calculation.
Perhaps if you give a little more info on what it is, and numbers you've put in, someone here will be able to tell you what particular input your app needs for an accurate solution.
