Responded. Sorry to others for this of toppic, but i recongnize real navigation as most of immersivity of TWOS
The point of target motion analysis is not to trying to get exact values with precision of 0.1 degrees in bearing.
The point is to calculate roughly, youll get used to it and youll be very quick to find solutions without any map in one week if youll get into it..
The point here is to find out their course with precision about +-3 degrees.
That way you can easily calculate even your ideal bearing at waiting position to fire torpedo at their ideal AoB90 as their course+90 so when he will have course 20, your bearing at waiting position will be 120 and you cant miss..
Or you can easily detect their speed by binoculars - keep the same course and watch the bearing which you have the target at, try to manage to keep target at the same bearing for about 2-5 minutes - now they have exactly same speed as you -
You have complete firing solution from 10km away until they spot you!
-----
When i found this solution i started with absolute precise calculating with calculator.
I calculated even 4.th bearing with spiess line to get its distance and speed..
Then i found the speed is always about 8-10kts, so just find out how to recognize rough distance by differences between bearings at hydrophone in periods.
There's no universal rules for it, you have to start and find your own shortcuts - this is ultimately part of the fun and evidence TWOS is world for its own based on real navy situation (if you dont brake it by lowering your difficulty).
- Build your own unique kaleun approaches!
Then i started to round values to 1 decimal point (1.9) and start to calculate equations at paper.
Then i started to convert sine by rules from head (sine of every 6 degrees means 0.1 - so sine(6)=0.1, sine(12)=0.2, sine(30)=0.5) and so.
Then i started to use this sine and triangle rules even in target approach - When you know their rough course is 8, your from west of them is 10, you know, your tracks connects under angle of 2 degrees.
If you see them at your bearing 140, you know second angle of triangle=140.
If you remember from school, every triangle's inner angles sum is 180.
So his current angle on bow agains you is 180-(140+2)=38 degrees.
Now you can simply calculate how distant he will be if youll wait for him to come to you here if you know his current distance.
It will be his current distance * sin(his angle on bow - 38)=his current distance * sin(38) = his current distance * 0.6.
Thats cool huh, and that was just from head like if i would multiply something by 10...
Thats rule of sine.
Your brain just start to use this shortcuts on its own and one day, you find out, you can build solution just like that in head like kaleuns in movies or documentaries.
Now dont think i am some super-kapitan which kills everything around just by snap his fingers, i constantly make mistakes and miss my eels, but most often when i find ideal position from about 1km in 90AoB of my target i hit...
And my eels dont explode many times even in those situations
I am just hungry for submarines theories to enhance my immersion while i play sims..
Sorry Vecko, i just love it!
