Nav radio on the 190 A8

Recommended Posts

I never really stopped to fiddle with it, but today I took notice of the lorenz-type nav device on the upper-right portion of the A8's instrument panel. 

 

Interesting, unlike most equipment I am aware, the vertical needle does not seem to point to where you SHOULD go, but rather to the side you are wrongly going. Is that correct historically? 

 

Also, the vertical needle seems dead. IIRC this was supposed to be a blind-landing device, the horizontal needle giving you range to the runway. For direction finding it is not relevant, I was just curious if it works as intended or if it was left like that since it doesn't matter much.

Yes, I heard that before also. Interestingly just yesterday, while flying in a FW Dora, I noticed that the vertical needle did move also, which took me be suprise. I haven't tried that on any other planes yet.

Well.. purely speaking from memory as a hint for looking it up, so I might be very wrong but AFAIK the RadioPeilKompass was not an ILS-like or supporting device.
It was purely for actually finding a location (airfield) via instrumentation by giving you and offset (not a direction to, unlike the Bendix) from and a range towards a radio beacon.
This beacon was very often not actually located directly at the airfield (especially if it was a forward airfield, like a "Feldflugplatz" or "Notfeld") but at the nearest facilities handling communication (Funkmesstruppe, Platzleitung or Luftstab aso).
Some servers even consider this when they found historical data (KOTA fe IIRC) on some of the mission maps.

Thus you navigated to a prominent location or landmark from which you would and could not be mistaken in flying towards the nearby airfield.

In Il2 the distance needle does move - sometimes. But as most of the mission maps esp. in Multiplayer have the fields extremely close to the interaction zones you do not cover any distances where it triggers it to move, most of the time.
But I am pretty sure that on this forum there are many people with more detailed knowledge and direct links to sources who might want to chime in.

I remember a tutorial I saw on Youtube a while ago. Don't remember who made it,  but the guy claimed that only the needle giving direction was working. Thereafter I didn't pay much attention to that instrument until I acccidentally noticed that the other needle showing distance is also working.

 

Today I also checked with the Me110-G2 and the Me262, on Kuban and Rheinland maps. The needle is working on both planes/maps.

 

Don't know if the devs added this recently, but it's certainly a nice to have feature.

This video is most likely very old. It works for quite a long time now.

It shows your position, compared to the radio beacon. It was the other way round until about one year ago and I had asked in the 'Questions for the Developers' thread, we had back then, if it should not be the way it is now. The answer was, that it was correct the way it was. Looks like it was not.

All you need to know is here:

It might add to your mind brain twist, but if you go down to Fig. 13 it offers some answers.

 

Same stuff, in german:

Go down to Abb. 44 (= Fig. 44) and there's the translation:
- plane is right of the center line = dash-zone = AFN points to the right "R"

- plane is left of the center line = dot-zone = AFN points to the left "L"
