Has anyone else noticed that the HDG bug and the HDG flown don't match?
-
I can't say for certain if it's every time, but I've noticed when using the autopilot that when I set a heading, the track flown and the heading bug are usually off by somewhere in the neighborhood of 5-10 degrees? Has anyone else noticed something similar?
-
@piedmonitor , If there is any crosswind present, your track flown will always differ from your heading. Switch to the default external view, or overhead external view, and see if the aircraft appears to be crabbed. If it is crabbed, you are flying in a crosswind.

Indeed they don’t. I was flying around the Lake District this morning for about an hour. The HSI had physically drifted about 10 digress. I’m guessing this is another bug? Can this be quashed in the next update please.
-
@captain744 since read that this issue has been noted and will be fixed in next update 😄
-
@RetiredMan93231 I wouldn't expect such a basic autopilot as the one modeled would adjust for the wind, though. I'd expect to have to make that correction myself.
-
I agree, the drift is not taken in account as it should in real life IMO.
The autopilot in Hdg mode seems to follow the wiskey compass (magnetic) heading instead of the heading bug set on the Direction indicator.This one should be pretty easy to solve I guess :)
-
@captain744 , The Heading Indicator (HSI or DG) will drift over time, as in the real world, so they must be occasionally resynced with the Compass heading. This can be easily done by pressing [D].
-
@RetiredMan93231 wouldn't this not happen? Firstly, there's no dial that I can see which adjusts the HSI heading indication, and it's tied to the whiskey compass anyway right?
-
@RetiredMan93231 The HSI shouldn’t normally drift.
-
Of course, the drift is a natural behaviour, but when the DI shows a drifted (wrong) heading, the autopilot is supposed to follow the bug set on the DI.
-
Assuming you are using the Direction Indicator (-not the HSI)
Test scenario once you are airborne @ cruise altitude:
1- Press 'D' key, so the DI indicates exactly the heading of the whiskey compass
2- Adjust the DI heading bug in front direction
2- Turn On the autopilot in HDG mode
3- Observe: the autopilot follows exactly the heading set with the DI bug which is correct
4-Turn the left knob on the DI (Gyro calibration drift) so the DI bug turns about 90° left or right
5- Observe: the aircraft heading maintained by the autopilot does not change at all!I'm not sure that someone can convince me that this is a normal behaviour ;)
