ISSUE DESCRIPTION

Description of the issue:
When using analog CDI/HSI for tracking VOR, the needles will remain centered on the instrument regardless of OBS setting.

This issue is not seen when using a glass panel display, such as the G1000 or Epic 2.

If applicable, which aircraft is experiencing this issue:
Beaver w/Radios, C172 Basic

[PC Only] Did you remove all your community mods/add-ons? If yes, are you still experiencing the issue?
Yes & Yes

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)?
Every Time

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

1. Select an analog CDI/HSI equipped aircraft
2. Load C&D at KPRB
3. Tune radios to PRB 114.30 & MQO 112.40 – both VOR can be received when on ramp at this location
4. Observe HSI/CDI needle(s) immediately center
5. Rotate OBS and observe no deflection of needle(s)
6. Repeat this process in a glass cockpit-equipped aircraft
7. Note proper operation of instrumentation

YOUR SETTINGS

If the issue still occurs with no mods and add-ons, please continue to report your issue. If not, please move this post to the User Support Hub.

What peripherals are you using, if relevant:

[PC Only] Are you using Developer Mode or have you made any changes to it?
No

[PC, MSFS 2020 Only] Are you using DX11 or DX12?

[PC Only] What GPU (Graphics Card) do you use?

[PC Only] What other relevant PC specs can you share?

MEDIA

Please add a screenshot or video of the issue occurring.

Beaver OBS set to 90°:

Corvalis TT OBS set to 90°:

EDIT: Important

The GNS equipped examples are in error. I neglected to set them to VLOC.

However, the analog radios in both the Beaver and the C152 are still afflicted by this bug.

Provide extra information to complete the original description of the issue:
• I enabled the Marketplace-purchased Carenado C170B to test and, interestingly, it is not affected by this bug. Are the 2020-based aircraft immune to this?

Provide extra information to complete the original description of the issue:
• The bug manifests itself differently in the DV20. The needle seems to just stick in whatever position it happened to be in upon aircraft initialization.

@NixonRedgrave I was able to reproduce this issue with the DHC2, but not with the HU-16, either streamed or running locally. Tuning Nav1 112.40 and 114.30 VORs worked fine at KPRB, with CDI needles responding to knob inputs correctly. I started on the ramp, following your instructions, and flew around the airport, but didn’t see any tracking problems at all. The CDI needles moved and responded to OBS knob inputs as expected. In the HU-16 both the HSI’s CDI and secondary one are tied to NAV1.

I tried a few other airports with nearby VORs as well, and there were no problems there either.

I don’t doubt you’re experiencing an issue, but maybe a full reinstall is in order if you haven’t tried that? I’ve heard of it helping for various bugs after release.

Sorry I can’t be of more assistance.

[NixonRedgrave]

Interesting.

I have reinstalled on both computers.

I will recheck on both again, tomorrow.

Possible dumb question — you aren’t running a different/newer build of the aircraft than the rest of us are you?

Thank you very much for the feedback!

[Ramasurinen]

@NixonRedgrave Nope, I can run the release build of the HU16 or an updated local version as needed, and there is no change, as expected, as I haven’t touched the Nav radios.

[NixonRedgrave]

Ok, I just reinstalled the sim on my laptop this AM.

I am sitting in the HU16 right now and tuned to PRB 114.30 and rotating the OBS 360° and the course deviation needle is not moving.

Is there something else electrically I need to power up beside the Battery and Radio switches? The Inverter is on by default.

I can/will check this later or tomorrow on my desktop.

EDIT:

Got it, the GNS was set to GPS and not VLOC! Duh!

Thank you for the bug report.

We have created an internal ticket to see if our team already has this logged, and if not they will attempt to reproduce the issue and create a new bug report. This item is now marked as feedback-logged. If there is an existing bug report or one is created, we will move this thread to bug-logged.

Has there been any progress on this bug report? I’ve had one flight in the last 10 where the analog VOR/CDI needle worked. It seems very hit-anbd-miss. In my experience, if it works on one plane, it tends to work on any of them. The planes I tend to fly and notice it on are the C152 and the Beechcraft Staggerwing.
