HDG mode not holding Heading

[Rhinozherous]

Hello! 

Latest beta here. After a time I flew the KA50 again and noticed that I had to hold the heading with rudder myself, alltough HDG mode was on.

 

In the past the shark always held the heading quite stable, but now I cant go heads down to the shkval without yawing all over the place.

 

All AP Modes where on except of ALT. Flightdirector was off. Helo was trimmed and he held very nicely bank and pitch, but no auto yaw control.

 

Is this a bug or something new I missed?

Check the Options>Special>Ka-50 for the "Rudder Trimmer" option to be checked. It works for me. I checked from a hover condition. Channels have a limited authority and it's possible that authority limit is reached before achieving desired heading to hold especially with dynamic changes in required rudder.

 

If you think there is still an issue a track file would be helpful.

Enabling unrealistic rudder trim wouldn't help the malfunction of the Yaw AP channel. You'd only gain a way to trim against the malfunction.

If rudder trim is unrealistic then you'll have to keep rudder input approximately in the right place so that the limited channel authority can do what it needs to.

 

If rudder is grossly misaligned with required the channel authority is insufficient. Yaw AP should function just as well with either special option as long as your pedal input changes accordingly.
