CanadianCaptainMoustache 23 Posted January 27, 2022 Share Posted January 27, 2022 The HSI CDI needle, whether in VLOC or GPS mode, is far too insensitive compared to IRL and needs to be cranked way up. Also this system should not auto-slew when you select a GPS waypoint. The CDI should have to be manually turned onto your proper bearing. Link to comment Share on other sites More sharing options...
Aerosoft Aerosoft Team [Inactive Account] 51558 Posted January 28, 2022 Aerosoft Share Posted January 28, 2022 We are reading the standard sim values for this, do you see the same issue in other aircraft? Link to comment Share on other sites More sharing options...
CanadianCaptainMoustache 23 Posted January 28, 2022 Author Share Posted January 28, 2022 No, this deflection issue is only in the Twin Otter. For reference, CDI full deflection should only happen at 10 degrees when in nav mod, 5 nm when in GPS enroute, down to 0.3 nm in approach (for a WAAS GPS which this is), and typically 2.5 degrees in localizer mode. The CDI slewing issue happens in a few other aircraft and is config-dependent so I know it can be changed as well. Link to comment Share on other sites More sharing options...
CanadianCaptainMoustache 23 Posted January 28, 2022 Author Share Posted January 28, 2022 At a quick glance, the instrument config has the same sensitivity for LOC and normal NAV mode for a start Please login to display this image. Link to comment Share on other sites More sharing options...

Deputy Sheriffs Secondator 643 Posted January 28, 2022 Deputy Sheriffs Share Posted January 28, 2022 We checked the VOR and LOC values and they are all correct with 0.5 degree deviation per point in LOC mode and 2 degrees per dot in VOR mode. With GPS mode we'll have a close look over the weekend. Link to comment Share on other sites More sharing options...
CanadianCaptainMoustache 23 Posted February 1, 2022 Author Share Posted February 1, 2022 I gave it a mild test and it looks like in GPS mode it's about +/- 60 degrees for full deflection while enroute. Yikes! Link to comment Share on other sites More sharing options...

Huge difference. FYI, your CRJ indication is exactly the same as the Embraer. Please login to display this image. Please login to display this image.

Yikes! GPS does not follow degrees but cross track distance. We have changed the enroute setting now from 2NM per dot to 1NM per dot which is the normal enroute setting (checked from KI 525 and GNS 530 manual). With full deflection it means 5NM cross track error. This will be included on the next update. Link to comment Share on other sites More sharing options...

In approach in particular it is far too insensitive and should be, as stated before, as low as 0.3nm sensitivity Also, will the auto-slewing be removed while this is happening?

Automatic turning of the HSI will be also fixed. About terminal and approach phase sensitivity. It's implemented in the code with "GPS APPROACH MODE" simvar. However, I am not exactly sure how that variables activates and it's behavior beyond our control. Link to comment Share on other sites More sharing options...
