HCF - Consistent drift to left/right taxing on certain places.

I believe the HCF function is simulated in the Inibuild A350 since 1.0.9, and it has not worked in some scenarios. On some taxiways it has a tendency to always turn right/left and requires pilot intervene to stop the aircraft from turning. One example is taxiway H/J at VHHH, westbound taxi. Can the team please take a look at the code for the HCF function? Thank you.

Hi,

So ultimately HCF functions where it remember the last heading before the user ceases inputs to the NWS/Rudder Inputs, what can override the heading control in sim is anything from noise coming from input devices, weather. If possible attempt to view the input devices when the aircraft is taxiing in clear, calm winds, to see if there is any ghost inputs that could be occurring.

Thank you.

I can confirm no noise / ghost input during taxi. It happens in WF Scenery VHHH when taxing westbound on Taxiway H/J, it happens in other places too but Hong Kong is the one that I remember most clearly. Please try.

Hello, I have tried it,

This is my Volanta track taxiing down Juliet to RWY07R

I have 0 deviations on the taxiway

I'll take another look tomorrow. Thanks!
