HSI / VOR1 Misalignment

Sender46

The HSI CDI does not align correctly with VOR1.
For example, with 198 degrees set on VOR1 the HSI CDI is at 202 degrees.

Hmmmm, it appears my HSI CDI was following the GPS course when I thought it was following VOR1. Caught out yet again by not having any way of knowing whether the hidden click spot is in NAV mode or GPS mode without Cockpit Tooltips on (which I hate using because they are not realistic) :( Maybe I should have realised that the error was because I was in the wrong mode but I guess I was fooled by it being only a small error.

How does a real pilot know what mode is selected when? (using the GPS 100 set up). And whatever that is, can that not be implemented in the sim?

Sender46

I just flew again with NAV mode definitely selected on the hidden clickspot and the HSI / VOR1 are still misaligned.
For example, with 189 set on VOR1 the HSI CDI is on 204 degrees. This is 45 miles from the VOR (OTH 112.1).

Is anybody else seeing this error?

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 will be fixed in the next update.

@Martyn Yay! This update gets more exciting every day

Sender46

@Martyn Thank you. I love how the change log keeps getting longer :)

@Sender46 This next update is going to be epic. So many fixes and so many QoL improvements.

This seems to still be an issue in 0.4

Sender46

@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).

N293WK

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:

N293WK

Strangely, NAV2 is also off but less so:

Sender46

@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?

N293WK

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)

Sender46

@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?

N293WK

@Sender46 Just submitted 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:
