Your tool is superb, but it never ceases to amaze me how people always try to find the AOB once they have the target's course
when historically exactly the opposite was done
. Trained spotters watched the target and made estimates on the AOB, with the only purpose of getting an estimate to the course, not the opposite
Anyway, since your tool also works backwards -from an AOB you can get an estimate of the course- it is helpful to plot course and calculate intercept points and manouvers.
As in real life was done
