Dick O'Kane lead angle calculator

I'm goin' down · 01-03-10, 12:21 AM

A similar lead angle sheet was prepared by Old Tex for the Cromwell attack. It may not be needed if the Solution Solver is employed. Badger must have come up with his formula on his own, not realizing that Mr. Gutted had been there and done that. But, I had forgot about Gutted's chart, even though I nominated his Solutiton Solver as a program/mod of the year along with Easy Aob (the later, which was runner up to mod the year.) Any tool that is handy for use in killing ships is a good thing in my opinion, and the tool promoted in this thread serves that purpose as noted in post 7.

handy tip for the wheel:

Finding a convoy's course from the radar screen:

1. Rotate Own Ship dial so it's blue arrow points to your correct course on middle dial.
2. Orient the wheels (right click + drag all of them) so the outer dial's arrow is under the periscope line.
3. Look at the convoy on the radar screen.
4. Match the target dials orientation to that of the convoy on the radar.
5. Read off the convoy's true course from the target dials blue arrow on the middle dial.

To parallel the convoy.. follow the target dials blue arrow across to the outer ownship dial to get the relative bearing to turn on to. Turn your scope to that bearing and issue the turn-to command. Don't forget to update the own ship dial to the new course afterwards if you intend to keep using the tool.

I probably mentioned that before.. but i dont think i put it into the manual, so i figured i'd just throw that out there again.

One of the points made in post#15

was that hitting the target exactly at 90° results in more duds.

Urge

well.. then rotate the dial so it's at 85 instead of 90

yes, gutted, it does not take long to set up the Solution Solver, but it takes a little longer than just plugging the data for a lead angle calculation. I have become proficient at using the program, except I do not use the ship's length feature, so the time factor is not an issue for me.

It is especially not a problem now, as my game computer got screwed up by a mod and is not functioning, I lost sectors when I ran chkdsk, then windows would not boot, then my son reset the Beta switch, and as of this weekend I have lost all data on the disk.

Be careful with the NMMO mod to TMO 1.9. I suspect it may be is the culprit, especially the new real environment option, as I received corrupt file notices.

You miss the point entirely by confusing lead angle with aim bearing. In the Dick O'Kane method the TDC is the lead angle calculator and it is always correct, not matter what aiming bearing you choose, so long as the data input into the TDC is accurate.

With the Dick O'Kane method you may aim on just about any bearing you choose, really. Your lead angle will be correctly computed by the TDC, which will send the torpedo on the correct bearing to intercept the target.

The advantage of using the TDC instead of a chart is that human error is eliminated.

Captain Robbins, why did I figure that you would post in this thread?

If you were addressing my post, I was assuming the TDC was not activated. But I will think about what you wrote, which I assume to be accurate.

By the way, Happy New Year.
