1.- Move the B ring (True course) until its 200º mark is at the bow of your own ship silhouette in ring A (Matching the 180º mark in the A ring)
2.- Move the Periscope transparent layer to the 45º mark of the A ring. (Here's the reason why it is reversed! To move your scope "right" means in fact moving in the opposite direction the lower part of that wheel, so that the upper shows the target with the correct AOB side)
3.- Last, set the estimated AOB of your target (60º port) in the B ring.
Result: Your target's true course is 105º  , as you can now read in the B ring (True course ring) |
Own ship is on course 200 degrees.
Target is on 45 degrees relative bearing.
Target has Port 60 degrees Angle on the bow (AOB)
Set this up on the SACF and see that target course is 105 degrees.
