The "Whiz Wheel", used by manual Weapons Controllers to compute intercepts. Actual size is about 9" in diameter.
There was not a vast majority of controllers or WCTs who became proficient in its use. Most WCTs hated it because it took interest and some time to learn.
Those who were proficient were the instructors at 3625th and those who attended the IWS Manual Weapons Instructors Course. There were also the control geeks like me that made a point of learning all of the finer points of intercept geometry and theory. I also attended both of the above courses.
Although I may have forgotten some of the finer points, like the double offset stern and computing odd an angle of bank turn radius, I could still compute any intercepts using all parts of the Whiz Wheel.
