SWO Radian Rule 4+

Are you the Conning Officer assigned to make the approach for an UNREP? Do you struggle doing "public math" with the radian rule, especially under pressure? Have you been relying upon a paper cheat sheet and wish you had an app to automate the radian rule and provide you instant results? Then SWO Radian Rule is the answer to your prayers!

Designed from the ground up with the Conning Officer in mind, SWO Radian Rule provides an intuitive, user-friendly interface that clearly displays all of the critical information you need at a glance. Simply dial-in the appropriate Degrees Offset and Range to Guide, and SWO Radian Rule will do the rest, instantly calculating estimated Separation Alongside, target Degrees Offset, and your target Bearing to Guide. SWO Radian Rule allows you to select on which side of your ship the Guide will be (PORT or STBD), R Corpen, and target Separation Alongside. And, SWO Radian Rule is compatible with Darken Ship requirements, just in case you're conducting a night time UNREP.

Whether you're a brand new Ensign or a salty ol' Senior Officer, SWO Radian Rule is an invaluable tool that you'll wish you had sooner. Make a seamless approach on the Guide every time with the help of SWO Radian Rule!
