ISSUE DESCRIPTION

Description of the issue:
There is a discrepancy between the Airspeed shown in the cockpit gauge and that shown in the cockpit HUD.

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)?
First seen v1.6.31.0 (just acquired the aircraft), but also reported by @nierga8 on March 28th, here.

REPRODUCTION STEPS

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

  1. In Settings / Flight Interface, ensure that “HUD in cockpit view” is enabled.
  2. In free flight, select the Cessna 195, start a flight at any airport, select daylight & clear skies preset for convenience.
  3. Take off. Note the difference in airspeed values. In the screenshot below, the gauge is showing ~126 knots, the HUD 108 knots.

The gauge isn’t in miles per hour?

3

It is in MPH.

4

Thanks - you are probably right, but IMO the airspeed should match - i.e. if the gauge is knots, then the HUD should be in knots too. Ditto for gauges that showed MPH, KmPH, TAS, IAS, etc.

5

If I recall it wasn’t till the 1970s when Knots were used over MPH (at least in these type of aircraft).

As ever, options would be best. I see value in keeping the HUD in the most common (modern) unit so that users who might only be familiar with something like knots can have familiarity via the HUD in aircraft with alternative measurements on their instruments. But of course, everything aligning would also have its benefits - so something where the units are customizable would be the best of all worlds.

@Zadma
That is a fair point, though you’ll notice that the HUD airspeed has no unit of measurement that would indicate that it is using a different unit of measurement than the panel gauge. I have a feeling that most of the 15+ million users of MSFS have probably just glanced at how their units of measurements were configured in settings, never bothered to change them & probably do not care one way or another!

In any case, it’s up to the devs to decide if this issue is by design or a bug. :slightly_smiling_face:
