False ship data?
 

Hi,

I had a problem in play.
During an attack, I took my measurements for the RAOBF disc, and I got this:

If I look at the result correctly, in X6, with a height of 7.5 (1200m) and a length of 23, I get an AOB of 52.5 .
Since the ship has a leaking heading, the true AOB would be 180-52.5=127.5°.
This is totally false.

To the eye we can see that the AOB does not exceed 105/110°.

Only erroneous data can give such results.
The mast height and/or length of the vessel must be wrong.

Am I getting the wrong idea, or am I correct?

Nobody?

There is indeed a possibility that not all the values from the recognition manual are 100% correct. Unfortunately there is no 100% valid way in the game to measure ships length, height and other values...

May be a conversion error between units of measurement (feet/metres)...

Could someone with the feet version be able to give us the values he has?

I calculated the 102 ° AOB with the "Gegnerlage Berechnungstabelle" ...
:salute:

I've decided to take a different approach to checking this ship's values.
I created a mission with the ship AOB 90° at 2000m.

I was able to determine the values at once:
Height: 5.5 ticks for 2000m corresponds to a height of 27.6m

length: 17.4 ticks for an AOB from 90° to 2000m gives us a length of 86.9m

So there are a lot of wrong values in this identification book. I hope there aren't too many, it would be really stupid to miss out on it.

Thank you for your help.

For info, with the values of 7.5 ticks of height and 23 ticks of length, I find an AOB of 104-105°. :Kaleun_Cheers:

What have you use to calculate this?


I can't find anything on the forum about "Gegnerlage Berechnungstabelle."

delete

Why did you delete my message?

You miscalculated.
Did you take the values from my screenshot?

On the ship's identification book, we have a height of 22.6m and a length of 86.9m

That gives us this theoretical aspect ratio: 86.9/22.6=3,485

Now, the observed aspect ratio in ticks: 23/7.5=3.067

ratio observed aspect / theoretical aspect ratio X 100= 3.067/3.485 X 100 = 88% X 100 = 88

If we go back to the Gegnerlage Berechnungstabelle:

We're getting an AOB of 63°
And since the ship is fleeing: 180-63=117°

Forgive me but i delete MY answer before..but yess i (bit) miscalculate because I was in a hurry, you right

True 86.9/22.6=3,4

Relat 24**(12x2)/7.5=3.2

3.2/3.4=0,94--->94%---.>72

180-72=108

**
I had read in an old tutorial,
better multiply x2 tick towards the bow (in our case 12, and not 12 (bow) +11 (stern) .. and no take more decimal...the aob is still approximate
I feel comfortable using this method
Forgive my bad english
:Kaleun_Salute:

Okay, but did you get a good look at my test at 2000 meters?

It clearly indicates that the ship's I.D. is incorrect for this vessel.

If we quickly recalculate with the corrected height (27.6m instead of 22.6m), we get:
Theoretical ratio: 86.9/27.6=3.149
observed ratio: the same as before, 3.067 (if we take your approximation of 3.2, we are higher than the theoretical value, not top but comprehensive)

3.067/3.149 X 100=97.4%

And we obtain with the Gegnerlage Berechnungstabelle: 77°.
Let a real AOB of 103

Anyway, all this to say that maybe we should check the values in the ship's identification book.


PS: my english is pretty bad too, I can thank DeepL for the translation

Hi Nazaka
In your test mission ship is
- 2000 m
- 90 aob
Right?... If so really wrong ID book..
Which test mission you play?

I created him.

If you want to check it out:

all you have to do is put it in the "SingleMissions" folder.

You'll find it easily, it's the one without a name (I don't know why).

Just to chime in here, you seem to have a handle on this.

The attack wheel on your scope has limitations. Once a ship passes the 90deg range AOB... the markings on the wheel do not align. It's hard to explain without showing. When a ship is going away from you, you will have negative or as you say "erroneous" results. With practice you can still get accurate shots, but the numbers will be in the negatives range.

Good luck!

Negative value?



no, as the AOB exceeds 90°, the result obtained must be subtracted from 180.


A.3 [In cases when ship is moving AWAY from you] AOB when exceeding 90 Degrees.

1. If the ship is moving away exceeding 90 degrees, use formula:
180 Minus Determined AOB from the steps taking in A.2.

bstanko6, I checked the ship that I had a problem with, and it was an error in notation of mast height that was the cause of it

Ah ok. But the problem you named is common. Glad you figured it out.

thanks i will try to test and let you know

If it's a known concern, why hasn't anyone made a subject to list it?

I just modified the CFG file for the ship in question. And that was accounted for by the ship's identification book.

I'm testing most of the ships, I'll give you a summary of the ships to be modified if you wish.
