[NEED TRACK REPLAY]Yaw oscillation during crosswinds

[Hummingbird]

Noticed that the aircraft seems to oscillate a lot in yaw in a crosswind, feels quite excessive and odd. Noticed it whilst flying low on the Growling Sidewinder server where the F-16 felt a lot more unstable than the other aircraft down low. You can observe the rudder swing left & right quite rapidly in this case.

We do have some oscillation issues reported however if you want us to check always add a short track replay showing the issue

 

thanks

This doesn't make sense because there is no crosswind for the aircraft itself, except during the ground - air transition (and vice versa).

Turbulence could /should be a reason.

Turbulence only seems to appear during crosswinds ingame it seems though, and it appears a lot more severe for the F-16 for some reason, esp. in terms of yaw oscillations which is quite odd. I'd expect more of a bumpy ride in terms of pitch, but not that much in yaw. But like BigNewy said it could be part of the other problem reported.

 

I'll try to record a track later this weekend.

I still don't understand. Once you are in the air there is no such thing as crosswind. What is crosswind in your opinion?

 

IRL turbulence mostly disturbs roll and yaw, not so much pitch, but vertical speed.

Sure there is...

 

Add a strong north wind when you're trying to maintain a ground track of 090.

 

Your nose has to crab north of east in order to hold that ground track.

NO! But that's a common misconception.

 

For the aircraft itself, its handling and performance it's irrelevant where the wind comes from! It's flying in a steady moving mass of air.

(Steady) wind doesn't have any effect on an aircraft in flight.

 

The only things that change due to wind are ground speed and ground track, but that's navigation, not aerodynamics.

So that's why it's a bug.

Rather difficult to confirm without a track.

Go on Growling Sidewinder and fly at low level with the F-16, it should be immediately noticable.

I don't use multiplayer. Just tried 50kts wind and maximum turbulence and the maximum yaw deviations were 1-2deg.

 

But they are a bit strange since I didn't encounter real oscillations. The nose yawed 1-2deg and then stayed on the new heading for a few seconds instead of immediately swinging back to the original heading.

We need a track, as specified. Thanks.

 

Also, we don't need bickering and fighting, so please leave that out as well.

Does it need to be a video recording or a DCS track?

Always a track replay first, as short as possible showing the problem, to report any issue we need to be able to reproduce it, a track is the best way.

 

thanks
