With the the Attack disck you can:
1: Determine the fastest course to intercept a reported contact
2: Determine a course and speed to waylay a reported contact
3: Determine the true course of a target from bearing and angle on the bow
4: Determine the angle on the bow of a target from bearing and course
5: Determine the angle on the bow of a target from its aspect ratio
6: Determine the range of a target from its mast height
7: Determine the speed of a target by plotting its position over time
8: Determine the speed of a target from its length
9: Determine the speed of a target with constant relative bearing
10: Determine the speed of a target with a changing relative bearing
11: Determine the speed of a target with two bearing and range observations
12: Determine the time for a target to reach a future bearing
13: Determine a perpendicular attack course to a target
14: Determine the distance to the track of a target
15: Determine an optimum speed for attack position
16: Determine the lead angle for a perpendicular attack with 0° gyro angle
17: Determine the torpedo gyro angle
18: Determine the torpedo run time
