Calculating Speed - Correctly??

Phoenix3000 · 03-26-07, 02:40 PM

Hi all,

After getting rid of the stuttering gremlins and finally having a smooth-ish installation of SH4 I decided to begin from the beginning using all realism settings except for external camera (for the eye candy).

I quite understand the TDC and can accurately track a course and locate distance etc. but the main problem I have is accurately finding speed of the target.

For example, with a cargo merchant in calm seas, using the bow wave and travel across the periscope you can roughly guess a good speed - say 6 knots - in bad weather it's a lot harder!

But, when faced with naval ships - especially destroyers, cruisers and battleships etc. that can go up tp 30 knots it is much more difficult!

Countless times I have a good target track and waiting to shoot 90 degrees off their port or starboard, but the speed gets me most of the time.

The 'manual' says to click on the chronometer for as long as possible and by magic it works out a good estimate of the speed - this has never worked - I guess one of the restrictions with high realism settings.

So, without a nomograph (like SH3) I find it extremely difficult to to get the speed - a crucial part of the puzzle, without getting so close that every escort is on top of me.

Can anyone please advise?

What has (and hasn't) worked for others here?

Cheers!
