Troubleshooting

 

Q. The HSI and RMI compass rose is showing a different heading than the whiskey compass, and/or I must turn the HDG bug way off the radial to hold the correct heading.
A. What you have here is simply a case of uncorrected magnetic drift where over time the directional gyro loses sync with the magnetic compass as you continue to pass across the earth. If you have Gyro Drift enabled in your aircraft realism settings, this will occur. To resolve this, all you need to do is to synchronize the gyro to the magnetic compass by pressing D every 10-15 minutes, and the problem will disappear.

Or disable Gyro Drift in the simulator's realism settings.
