image where point B ended after the first read-
ing. After calculating the mils for each image,
You then can add them together to get the total
azimuth read-ing.In the (Fig. 5) image below the
ship is longer than the total 100 mils available on
the reticle. However, by doing the foregoing mil
calculations, you can now obtain the ship’s total
mil azimuth of 130 mils (60 + 70 ).
4.2.3 Upper and lower angel measurement
Upper and lower angel means the angel included
between any two targets (or two ends of a target)
against the vertical line on the reticule.
4.2.3.A Upper and lower angel measurement is
similar to measuring the azimuth. When the upper
and lower angel measurement is very small, aim
the cross center of reticule at lower part of the
target, read the scale value at the top of the target.
