Autohover~Turn to tgt, probs...

[deltahawk2008]

Hi all

 

Just been getting back into this sim after some time away. Have drilled down into the manual. Ver 101. No problems with trim. But having some fun and games with Auto hover (which I like to use at a battleposition, so I can focus on targeting, getting my weapons away). At times I have gone into whirlygig mode, rotating in the hover at a high speed. Note stab aug on, ie pitch hold, bank hold, hdg hold Here is the mechanics of what I am doing1/slow to point where 000 is showing in Shkval, no discernible movement, vertically or horizontally 2/ Trim 3/ Set Autohover (sometimes this works better than other times) 4/ Use hms to get sckval in the ballpark of the tgt/lock tgt 5/ set to moving tgt, turn on tgt. Target is locked, all the symbology looks good. However, when the I go to add a little rudder to ensure all is lined up (Vikhr shot), the chopper remains locked to the hdg, no amount of rudder will bring the nose of the chopper around to get a lock? Now. I am wondering what are the preconditions so that all goes smoothly, modes on the autopilot etc? From the manual

To hover automatically over a ground-point after decelerating to near-zero airspeed, you

can engage HOVER mode using the following procedure:

 Set the “МАРШРУТ-СНИЖЕНИЕ” (ROUTE - DESCENT) switch to the neutral

position.

 Press the “ВИСЕНИЕ” (HOVER) button on the cyclic and this will illuminate the

“ВИСЕНИЕ” (HOVER) light on the overhead panel. The helicopter will then

stabilize above the hover point; radar altitude stabilization mode will engage;

and the “Нрв СТАБ” (RALT HOLD) light will illuminate on the overhead panel

 

I am assuming the neutral position is on the collective? What mode should the ap be in?

 

Thanks in advance to this somewhat wordy post.

Route/descent is refering to a little toggle switch you can see on your collective stick. i don't believe it is clickable but route and descent modes are both keymapped in your gameplay tab.

 

Basically it is saying if you want to hover, do not be in route or descent mode. Check your keymapping so you know what the keys are and remember to check your overhead panel lights - they will indicate if route is engaged (ENROUTE) i think. As for AP - i have all 4 channels lit up blue when going into a hover.

This part made me wonder:

 

Target is locked, all the symbology looks good. However, when the I go to add a little rudder to ensure all is lined up (Vikhr shot), the chopper remains locked to the hdg, no amount of rudder will bring the nose of the chopper around to get a lock?

That's weird. Do you mean the rudder has no effect at all? Did you check the virtual controls (RCTRL+Enter)? Since the autopilot has only 20% authority, you should always be able to override any AP channel including the heading in auto hover with auto turn to target engaged - it's just a matter of how much input you apply.

 

Could it be a hardware/controller failure that surfaces under these conditions? I'm not aware of any DCS: BS bugs concerning rudder input in auto hover. Then again, I've had very little experience with 1.0.1, I mostly flew 1.0.2 and never encountered such a problem.

 

As for stable autohover: fly really slow before engaging it and check that there's a solid cross on the HSI. If the longitudinal deviation line or the lateral deviation line move out of the center position, the hover is not stable and you need to re-adjust. The HSI is pretty much the most important instrument to tell whether or not the helo was ready to enter autohover.

 

Be aware that strong winds can also influence the Black Shark's capability to enter/maintain a stable hover.

Thanks guys. Have been flying around with R enabled. All sorts of problems when acquiring targets, turn to target etc. With R on, trimmed, one would appear to be in an arm wrestle with the AP, waypts etc. Which has shown me how much I dont know about the AP, PVI and Abris etc. A little bit of knowledge......
