I still can't get it
, my biggest problem is i still don't understand what you mean by 'twenty' degrees. Do you meant I have to move the slide rule two little ticks in one direction? none of which add up to twenty in value, or that I have to move the slide rule to a certain 'value' of twenty indicated by the slide.
This step is also not very well illustrated by your photo as from what I can see you have not moved the slide by 'twenty' by either the ticks or value
.
I attempted to use this method trying both the value and the tick method but both gave me angles of bearing that were clearly too low i.e: 025 when the target was clearly well above an AOB of 045.
Thanks for Writing this article by the way, I've been hunting round trying to find such an article for a while now since I knew dad still had his old slide rule hanging around.
