Way Point Navigation panel

[fraserweller]

I am trying to use the Way Point panel lower right front cockpit, is there a button that switches it on, I have tried pushing several and then selecting the way point number with out success. The ABRIS is working okay , the training missions are done by other pilots would that:joystick: make a difference to what I can use.

Right panel - PVI-800

 

Have you fully started up and configured your helicopter as per check lists or using the [LWin + Home] key command?

[bogusheadbox]

is there a button that switches it on

 

page 134 of the downloadable manual. Switch #11 is the one you are looking for.

 

Refer to the rest of the section on how to use PVI 800.

 

Remember PVI 800 and abris work in parallel but are independant of each other.

You mean extended manual p. 6-63, no 11?

AFAIK another mandatory operation is INU alignment (duration unknown).

I think it is better to say 'PVI-800 and ABRIS don't share any data' as i'ndependence' may not say it loud enough.

I used in this instance the downloaded english manual from DCS website. It is listed as 6-60 in the contents.

 

AFAIK another mandatory operation is INU alignment (duration unknown).

 

Yes, as the PVI 800 is inertial, it will require INU on and alligned (which happens by default when power to INU is turned on. Assumed this is complete as part of start up actions.

 

I am also unsure of INU allignment time, however the manual does mention a precise alignment option which can take up to 30 mins.

 

Looking further into the allignment time, i have found the following,

on page 304 (8-8 ) there are hud cues for

INU normal warm up, INU fast warm up, INU Emergency warm up.

 

There is also the pnk-800 which under navigation functions is described as doing the following

"Autonomous initial on-ground heading setting at extreme, accelerated, and normal with directional gyro alignment of the inertial navigation unit (INU) IK-VK "

 

Reading further into the PNK 800 it says

"Full stand-by readiness time in normal preparation is 15 minutes

Accelerated preparation mode is 3 minutes

Directional gyro mode is 2 minutes "

I have personally not looked for the hud cues nor have looked into changing the inu allignment speed. It may be something to look into.

 

Though we do know that inu misalignment (INU becomming inaccurate during flying) is not modelled and am therefore wondering if INU allignment time actually has any relevance on the performance of the instrument (though it did in the SU25t in flaming cliffs - IIRC needed 3 minutes)

Yes, the downloadable manual is the extended 500+ pages manual all should use. The manual describes the navigation system operation in detail starting from p. 13-26.

 

The only reason why I mentioned the alignment time is that when you say "wait for ... to finish" the natural question is "how long?" and AFAIK the manual does not say how long it takes for the initial, default INU alignment i.e. which INU alignment mode is used by default.

 

P.S. Funny thing, everyone calls PVI-800 a "navigation system" while it is only a control panel to the PNK-800 Flight Navigation System.

[bogusheadbox]

while it is only a control panel to the PNK-800 Flight Navigation System.

Well if we are being pedantic, bottom of page 13-26 it says,

"PVI-800 Navigation Control panel – this is the primary panel to control the PrPNK and it provides mode selection and interaction with the other PrPNK systems. The PVI-800 panel is located on the wall panel. "

 

And we know the PrPNK is a lot more than just the PNK-800

Anyway, back on topic.

For the life of me i cannot find anything that confirms the INU alignment time.

I have scoured the mission editor for options of INU alignment and found nothing.

I have also tried various combinations of start up whilst looking for the hud cues as listed in the manual and i cannot get them to show.

On the PVI-800 there are buttons for precise and normal alignment and i cannot get them to operate.

This is an important bit i think.

As soon as power is activated to INU and nav switch on, the PVI-800 will instantly display SELF co-ordinates that match correctly with INU initial co-ordinates. Reading on page 138 (6-64) button #18 it says that the initial point co-ordinate comes directly from the mission editor.

Taking this into consideration i am under the impression that INU alignment time is not modelled. I have tried to confirm this by buiding a simple mission with a couple of way points. Using the PVi-800 (as soon as power is established to INU) it gives me bearing and distance that corresponds correctly with abris and i have not allowed time for INU alignment

Add to this that the 1. magnetic variation dial 2. INU errors over time 3. Navigation tape on HUD don't work correctly, i can only say that this section of navigation isn't implemented in the game despite what the manual says.

Unless anyone has better information.

Didn't you hear me before? There's nothing about the alignment time :)

 

Well done with figuring out what is modeled and what is not. Rep inbound.

 

"The PNK-800 flight navigation system is a major component of the PrPNK (...)" and I don't see any PVI-800 functions that would affect other PrPNK components than PNK-800. It's irrelevant probably even to real pilots.
