Playing at full realism settings

For purpose of illustration the following pics have been edited to slide the TDC and AOB indicators closer to center.

This one I measured his course and maneuvered to be 1000 yards off the track at about 90 degrees to the track for the perfect angle shot. He's only doing 5 knots so nothing is happening too fast to keep up with. This pic is at 3000 yards range, with me 1000 yards off the track the AOB is starboard 25.

At 2000 yards range the AOB has only changed 7 degrees, starboard 32.

1500 yards up to 43, the AOB starts swinging faster, in 500 yards got a 11 degree change.

AOB 50 at 1350 yards, 7 degree change in 150 yards.

For those unaware, on the left side PK the lower ship is your sub showing the compass heading, upper is the target showing his heading. The arrow in the lower one shows the gyro angle for the torpedo, which way and how much it would need to turn if you fired at this moment. Upper dial arrow shows the angle at which the torpedo will hit the target, in this case about a 45 degree angle from the bow.

Here's the shooting setup we're looking for, close to zero gyro angle and close to a 90 degree impact angle. Note the AOB shows 80 degrees but the dial in the TDC shows the torpedo impacting at 90 degrees, the difference is how long it takes a Mark 14 at 46 knots to travel 1000 yards.

Again this is the training wheels study, note the crosshairs for a 5 knot target with a zero gyro angle 46 knot torpedo show 10 degrees off center at the moment of firing. When you move up to manual targeting and no map contact realism, if you want to use the angle off firing method set the bearing for straight ahead, speed zero AOB doesn't matter if the speed is zero, click the "send range and bearing to TDC" button so the gyro angle will be zero and the fish will go straight out of the tube. Range actually doesn't matter with the angle off method, set the crosshairs at 10 degrees right (010) for a target coming from the right, a target crossing your bows left to right set for 350. Whatever the range is when he crosses the 10 degree left (or right) crosshairs you fire, and if he doesn't turn or change speed the torpedo will hit. Get to know different convoys and merchant ships and the speed they usually cruise, that will tell you if your speed guesstimations are close. Make notes on what the angle off is for different speeds and different torpedoes, for a Mark 10 you would need to lead the target by more than 10 degrees, for a task force going 20 knots you would need a lot more lead angle.
