Got my first kill with the speed solver in SH5. Cimmaron Class Tanker, Length 139.6m
30 seconds from bow to stern = 9knots.
The speed was bang on.
The speed solver along with my physical AOB wheel, and he was dead without a single map plot or stadimeter reading.
Note:
Currently the Speed Solver is the only part of the program i use in SH5. I have a physical AOB wheel i use now so no longer need the integrated Intercept wheel (& the lead angle solver is redundant in U-Boats).
I'm thinking of making the speed solver a standalone app. Due to the modular design i used, it's only a matter of taking that control and dropping it into a fresh project.
