    There is definitely something going on here. Ignoring the VLOC/GPS setting, the NAV1 radial and HSI pointer don't align. This is easier to diagnose with cockpit tooltips turned on, so you can see what the actual setting is while turning it.

      Here's a demonstration of the offsets in the 4 compass directions:

        @vcapra1 The error is there regardless of whether NAV mode or GPS mode are selected on the hidden clickspot.

                  This seems to still be an issue in 0.4

                    @vcapra1 It's pretty close me with v0.4.0a. Only 1 degree out now (e.g. 330 on VOR1 & 329 on HSI). Maybe a little tweak needed (being nitpicky).

                      The HSI is spot on (give or take a degree, but that's fine). But the NAV1 radial is still off by 3-4 degrees at 180, and off by 1-2 degrees at 90 and 270:

                        Strangely, NAV2 is also off but less so:

                          @vcapra1 So what you're saying is the HSI needle matches the VOR1 needle (within a degree) but the Cockpit Tooltips don't match the VOR needles?

                            No, sorry. I'm basing this off the tooltips being 100% accurate, so the HSI matches the tooltips almost exactly, but the NAV ones do not. It can be concluded from this that the HSI and NAV don't match up at all times (the effect is most dramatic at 180, which is why I show that)

                              @vcapra1 That might explain why my navigation is a bit off when I compare my flight path with the flight plan on Little Navmap. Have you raised a ticket?

                                  @vcapra1 said in HSI / VOR1 Misalignment:

                                  ... I'm basing this off the tooltips being 100% accurate ...

                                  I concur with that. I just navigated a flight using the tooltip numbers and the flight path accurately followed the flight plan on Little Navmap. Like you say, the VOR dials are still inaccurate and more so at around 180 degrees. It's as if maybe the point that the VOR dials are rotating around is not their exact centre?

                                    Just realized that the heading indicator itself is showing the incorrect heading. For, example, if I point 090 degrees (as shown on the external camera indicator), this is what I see:

                                        Or maybe the external camera indicator is wrong as well, in which case I don't care about that.

                                        The HSI does match the HSI tooltip, which also matches the VOR tooltip. It seems to be the VOR itself that is inaccurate for me and that varies depending on the direction.
