Stoianm, I really appreciate your SH5 Youtube videos. I've watched a lot of them and I'm working through more of them to get better at SH5.

However, in the one quoted below, as well in the text, I believe you have a couple of mistakes.


1. In the first formula for AOB you have Aro/Arr when you should have Arr/Aro.

The ratio Arr = horizontal marks/vertical marks will always be smaller than or equal to (if on the target's beam) Aro = Ship Length/Ship mast so you need to use the ratio Arr/Aro.


2. If the contact is heading away from you, its AOB is:

AOB = 180 degrees - value from AOB slide ruller

That's because the ratio you calculate is the sine of the AOB:

sine AOB = Arr / Aro = sine (180 degress - AOB)


These are called supplementary angles (they add together to equal 180 degrees and their sines are equal).

The AOB is either the arcsine (inverse sine function return values from -90 to +90 degrees) of the ratio Aro/Arr (if approaching) or its supplementary angle (if moving away):

AOB = arcsine (Arr / Aro) [approaching]

AOB = 180 degrees - arcsine (Arr / Aro) [moving away]

where your slide rule takes the ratio as a percentage and gives the arcsine.

1)How to use RAOFB to find course, AOB, range etc from a ship or convoy with real navigation and realism 100%
2)How to choose the best position before making the final attack on a ship or convoy using Real navigation
3)How to add all the data in the TDC and how and when to fire your torpedoes
4)How to use AOB slide ruller to find AOB
5)How to use Navigator abilities to calculate the speed of a ship
5)This methode is the most fast and acurate methode that i tested so far in SH5 using Real nav, Manual TDCand Realism 100%
6)The time that we need to find all the data (range, course, AOB, and speed) for a ship or a convoy it takes less than 2 minutes
6)In this methode we will do less ploting on the map and we will use more visuals methodes


To play in this manner you need to have installed this mods:

1)NewUIs_TDC_6_4_0_ByTheDarkWraith or Magnum Opus

2)NewUIs_TDC_6_4_0_Real_Navigation

3)AOB slide ruller for TDW UIs and MO by stoianm ===>> DOWNLOAD

AOB=(Aro/Arr)*100===>> read value in AOB slide ruller

Arr = horizontal marks/vertical marks (use RAOFB to obtain the marks - i recomand Manos scopes from TDW UIs)

Aro = Ship Lenght/Ship mast (use the SOAN to find these values)

If the ship is heading to your direction than AOB = value from AOB slide ruller
If the ship is heading away to your direction than AOB = value from AOB slide ruller + 90 degrees
