OK, now I can hit stuff!
I am using the "fixed wire" method.
Here is how I do it.
1) Point periscope about 10 degrees in front of target. Press "=". This brings my sub's heading to where the periscope is pointing.
2) Once submarine has stopped turning, center up periscope on sub bearing 000. Your vertical crosshair should be in front of the target ship.
3) Wait for the target ship's nose to touch the vertical crosshair. While you are waiting, identify ship in recognition manual and determine ship length. When the target ship's nose touches the vertical crosshair, start stopwatch.
4) Wait for the target ship's stern to pass the vertical crosshair. Stop stopwatch.
5) Use this forumula to determine speed:
(1.852 * ship length in meters) / time in seconds
6) Go to the TDC.
7) Turn on manual data entry.
8) Set Angle on the Bow (AoB) to 90 degrees starboard or port, depending on whether you are on the starboard or port side of the target ship. It does not matter what your actual AoB is.
9) Dial in the target ship's speed.
10) Turn off manual data entry on the TDC.
11) Return to periscope view. Turn the periscope until the gyroscope angle is 000.
12) Wait for target ship to travel across crosshairs. When ship is in vertical crosshair, fire torpedo!
Note: If you don't want to wait for the ship to hit the vertical crosshair, you can turn the sub left or right to speed up the process. It is advisible not to fire until your sub has stopped turning.
WHAT I HAVE LEARNED.
First, The simulation is a lot harder this way!
Second, the simulation becomes much more an exercise of pointing your submarine instead of pointing your periscope.
Whoever changed my thread title,
manual targeting still sucks!
