Notes: The scales are obviously for artillery calculations. Use the wind side for simple addition and subraction problems and also to solve for true wind, winds in flight, true course and ground speed, true heading and true airspeed, and off-course correction calculations. Aviation and Flight computers, along with Load Adjuster Slide Rules used during WWII are. The wind side of the computer provides a graphic method of solving problems and displaying the answers in a useful form. Distance by Vertical Angle Measured Between Waterline at Object. Distance by Vertical Angle Measured Between Sea Horizon and Top of Object Beyond Sea Horizon. The calculator side of the computer uses conventional slide rule procedures to solve for multiplication, division, and unit conversion and employs scales for performing time, speed, distance, rate, fuel consumption, altitude, airspeed, air temperature, and pressure pattern calculations.
