WCS as nav backup??!?

[KewlerMouh]

Greetings Gentleman,

 

I have a burning issue I try to get solved for quite some time now. I went through the BS Manual and the web, but couldn't find an answer. So I am asking you, veterans, perhaps someone can help me:

 

I look for a way to use the WCS as a backup for the PVI 800, on which the AP depends. Only question is how? Is it possible? Again... how?

 

The idea came after stumbling over this thread from 2009:

I have found that when I lose hydro and my AP lights blink, I can switch the weapon controls system to handle navigation and I can land the helo.

I'd be very interested in this too!

 

But the only hint in the manual that I found is in the table of EKRAN messages (page 6-30):

Msg number: 34, Msg text: TURN ON NAV BACKUP

 

Sadly the procedure on how to do it, is not described.

 

Also, this would be interesting to know:

Msg number: 102, Msg text: WPN CTRL MEMORY FAILURE, description: "Turn on combat tasks backup"

 

Any ideas?

Flight manual, p. 177 (6-103):

 

Targeting Mode Control Panel

8. “ОСН РЕЖ”

“РЗН” (Backup navigation tasks on the combat computer) mode can

be used to update the aircraft’s inertial navigation unit (INU). This is

a less capable of way of updating navigation but both the navigation

and weapon computers can partially replace each other.

Excellent, that's it! Thank you very much Balion!!!

"P3H" is "FAIL" -->INU Backup va Combat Computer --I get my AP channels;
