can't keep my heading in hover

[ScEBlack1]

I have a question which I can't find the answer to in my manual which believe me I have searched. When I turn on auto hover, set auto turn to target and set trim and collective brake for stability and height I cannot keep my BS in a steady "heading" position? my BS will move to a particular direction usually the right, not s fast spinning but a slow turn.

 

How do I keep her to stay still and take advantage of auto tracking turn?

 

even when I turn off my auto heading and set my bird looking directly were I want she slowly will start to turn again, even if I trim my rudder pedals? any ideas. Thanks all.

1.)

Turn autopilot "heading" off. Turn to the choosen direction manual with pedals. Turn autopilot "heading" on.

 

2.)

If 1. not work adjust your rudder or your trim properly to the direction you want.

Post a Track of the behaviour experienced and we can then set you straight from there :)

you should do what zdXu. That's my best guess I guess :P

Another possibility: engage hms, turn on auto-turn (not heading hold), aim for the direction you want to look to, press uncage shkval, and then enable heading hold. It should go there. If you still have autoturn enabled, you can easily set a new heading by engaging your hms, looking to where you want to head to, and press the uncage shkval again.

Hope this helps :)

If you have to turn off the Heading Channel, you've done something wrong. RL Ka-50 pilots are not permitted to turn AP channels off.

 

So I'd second Viper's request for a track file to see what's happening.

[159th_Viper]

Aye - Leave the Dampeners well enough alone ;)

[Woots]

I use to experienced that from time to time also, sometimes still do. I'd lock a target in AUTO hover with "turn to target" on then lean down to focus on the SHKVAL to zoom in and identify the target. Right before I fire I see the "X" in the shkval and think WTH, lean back to see out the front window and my nose is 40 deg to the right. The shark had been drifting in yaw the whole time.

 

I read somewhere that you should hit the trim button after going into an AUTO hover. This did seem to help.

Thanks all, I will test these out and get back to you all, thanks again.

This general statement is wrong.

- at automatic take-off (win+home) there is at game-default the "hold altitude"-auto-pilot OFF.

- during landing there is nothing "wrong" with turning auto-pilot "hold altitude" also off.

possibly your engaging auto hover while not yet being in a stable (enough) position.

 

i think the manual has the actual parameters that are valid for engaging auto hover. i usually get my speed down to below 50 and no side slipping before turning it on.

No - Your Statement is 'Wrong' ;)

 

When referring to the 'AP Channels', ie Dampeners, one is not referring to the 'Altitude-Hold' but rather the Pitch, Bank and Lateral Dampeners.

What Viper said. The alt-hold thing is not a damper or stabilizer, whereas the others are. That said, maybe I should have been more specific but since it's "the three" that is usually on I assumed that that would have been clear. ;)

The pitch and bank are not "hold" buttons, though the alt and hdg are.. so isn't zdXu correct?:joystick:

[EtherealN]

hdg isn't strictly a hold - it'll be a hold if your rate of turn is below 3 degrees/s, but only then, and it has very limited authority even then which will also be overridden by align-on-target.

[MTFDarkEagle]

But why would a pilot be forbidden to disable the HDG blue button (dont know what name suits it now :P)

Back to the OP's issue: my bet is rudder trim.

 

Even with the Heading autopilot channels enabled, the autopilot can only input up to 20% control authority. If you've trimmed in, say, 25% right rudder, the autopilot's input will cancel all but 5%, resulting in a slow right turn. Proper (i.e., frequent) use of the Trimmer will prevent this from occurring.

[ScEBlack1]

Ok i figured out what my problem was...I was waiting to long to press trim after hitting Auto hover...If I immediately hit trim after Auto hover it stops it from yawing in any direction, thank you all for your help.

[Frederf]

Just so you know, it is possible to set up the Ka-50 such that during an "Auto hover" the heading hold is slaved to the navigation direction instead of letting the pilot trim any arbitrary heading. You'll notice that in this specific case the heading diamond on the HUD won't update when you press the trim button and the hold will want to drag the aircraft to face the DH/DT direction to the WPT. This nearly drove me crazy until I figured out what was happening!

 

But why would a pilot be forbidden to disable the HDG blue button (dont know what name suits it now :P)

 

Channel completely off allows the aircraft to enter into dangerous pilot induced oscillations with no appreciable potential increase in mission capability. It's a safety feature that rarely has any justification in being disabled.

"This nearly drove me crazy until I figured out what was happening!"

 

What was the solution for you to do?

For the same reason they aren't premitted to disable the pitch and bank dampers. And what Frederf said. ;)
