This was done using the degree marks on both periscopes, ie. land mass on the right was 10° to starboard while identifiable land mass on the left was 25° to port. Drew the lines, after calculating True Bearing to each, and voila, I've got my location.

Guys, dont forget that you can use "C" key to reposition your nav fixes and therefor help your navigator... Dead reckoning accumulated error can be corrected quite easily IF you have some landmark in sight...If not, well, then open four eyes and 10kn at max with minimal TC...:yep:

I always fixes my position by C (well i did not know about this shortcut, i used pencil :-) ) when i calculate one :salute:
+ i nerfed down max TC to 128 and its much better for me, i still had no lagging exploit when "something" is around :)

BTW: ****! i want that avatar out, keeping posting! :o

Range estimation
================
Binoculars and scopes have milliradian scales that allow to estimate/measure distances: "10" on the attack scope corresponds to "100" on the observation scope and represents roughly 100 milliradians (~5.73 degrees at low power magnification, at high power it's 4 times less: 25 milliradians or ~1.43 degrees).
One large mark on the binoculars represents roughly 10 milliradians (~0.573 degrees).
The markings are used as follows: given a target of height H that takes up M markings, its range R can be calculated:
R = H*k/M
where k is:
- 100 for attack scope low power and binoculars
- 400 for attack scope high power
- 1000 for observation scope low power
- 4000 for observation scope high power
Example:
Imagine you're observing a Liberty Cargo (mast height ~26m) through an observation scope at high power and ship's mast reaches "100" mark. Then the range will be:
26 * 4000 / 100 = 26 * 40 = 1040 meters
If you'd go up to conning tower and observe the ship through attack scope now (don't forget high power), its mast will reach "10" mark. Let's check the range:
26 * 400 / 10 = 26 * 40 = 1040 meters
RAOBF should give you something close to this value (between "10" and "11" on the range ring).
If you now surface and observe the target through your binoculars, it will take up 2.5 marks:
26 * 100 / 2.5 = 1040 meters
Mental rule for k:
"Normally x100, additional 0 for observation scope, additional x4 for high power magnification" ;)
Take note that horizontal scale on the observation periscope is in degrees. I don't know for sure why that is, and the sources are scarce, but I believe this could be helpful for navigation and for estimating target's angular size i.e. to set salvo spread angle.

Question, when i click the LI and click manual dive planes the auto dive planes remain highlighted. Whats the trick to manually operate them?

Where can i find this documentation? I tried even to search for strings from this post in TWOS files by total commander and found nothing..

There is no trick if you have properly activated gen.patcher and the snapshot? Did you?:hmm2:
