can this manual be used for manual FC solutions with TMO170

imput would be welcome but its a beauty!!!

muchas gracias

Hi! This is a very good question.

The thing is that it is independent of whitch scope or zoom you use! Now how come?

The theory behind is simple and you can make the tables fit the scope you are using at the moment i.e whitch mod you are using.

The principle is AOB=arcsinus (measured ratio/Fixed ratio) giving a result in radians.

To get the values in the table in degrees you have to multiply with 180/pi .

So what is Fixed ratio? It is the specific ratio between the length of a vessel and its mast height!

See above again. I use the data in meters or feet to obtain it.

The Measured Ratio is what you get from taking a reading with your scope at a certain moment.



2 x 7= length, 5=height

This last measure is up to you and what scope and/or zoom you are using. Strange? No.
It is all about a quote between two readings. No units involved at all. BUT important that you use the same length units for both horizontal and vertical readings!!


Now, this differs between scopes. Some have plenty of marks across the view like the "Maxoptics" in SHIII and horizontal reading can vary between 6 and 40 marks while the scope above (SHIV TM1.x) gives about 28 as maximum length with 12 as max height.

To make a suitable table for this is a job in it self and Centered75 adopted his for SHIV with basic optics.

With TM1.7 there is no problem since the zoom levels allow you to adopt in order to get values that fit into the tables. It actually works fine.



What I have done no is making an EXCEL spreadsheet with 26 columns and 11 rows. In each cell I have the formula for making the AOB depending on what numbers there are on the vertical/horizontal readings.

This mean I can make tables totally tailored for the scopes/mods i use. tedious, maybe but I think its' fun. Just put in the Fixed Ratio in one cell and the desired series of numbers for vertical/horizontal and the table shows data that you can copy and paste in to a MS word table or similar.

This I made yesterday for a Medium cargo in SHIII using GWX 3 Gold and the "Maxoptics" option.



Tested it and compared redings using map contacts "on" and it works!


The essence of it all is that it is not dependable at all on which mod/scope you use!


I also did just like "Centered75" and made a similar function for determining speed by clocking it and compare with the table so I made one for that too. Works as well. (The input here is ship length of course). seconds=Length/(knots x 0,5144). Long live excel!



The picture I have humbly borrowed from the printable SH3 Ship ID manual.

My aim is to make pdf-verions af all tables for both the newer ships in TM1.7 and those in SHIII.

Tested the tables above yesterday in the "happy times" mission using GWX3 and scored a hit on a m crgo from 2200m so I assume the tables are ok so far.


Will keep you informed and maybe later be able to have a thingie for download.
