What’s going on with the V/S it’s blank. Is there a fix?

Same problem here.  I had to reload MSFS 2020 because of program crashes.  After reloading it and re-adding Capt Sim's 777, the vertical speed is inop.  I am very familiar with MS2020, flying it since 2020.  This 777 add-on has been my very best airliner to fly.  I can't use it now because of the vertical speed flaw.  I have already made a post about this but got no response.  If you can find the problem, would appreciate being informed of it.  Good luck.

It's an easy fix, the only issue with my fix is the light doesn't turn on/off buthe V/S shows and you can adjust it. Here's the fix:

Go to: MSFS\Official\OneStore\asobo-vcockpits-instruments-b747-8\html_ui\Pages\VCockpit\Instruments\Airliners\B747_8\VSpeed

Open B747_8_VSpeed.js with notepad.

You'll find the following:

class B747_8_VSpeed extends Boeing_FCU.VSpeed {
    get templateID() { return "B747_8_VSpeed"; }
    shouldBeVisible() {
        return SimVar.GetSimVarValue("L:AP_VS_ACTIVE", "number") === 1;
    }
}
registerInstrument("b747-8-vspeed-element", B747_8_VSpeed);
//# sourceMappingURL=B747_8_VSpeed.js.map

Copy the following:

class B747_8_VSpeed extends Boeing_FCU.VSpeed {
    get templateID() { return "B747_8_VSpeed"; }
}
registerInstrument("b747-8-vspeed-element", B747_8_VSpeed);
//# sourceMappingURL=B747_8_VSpeed.js.map

Save it and it'll work. Make sure to make a copy of the original in case you screw up and maybe someone else can look into the missing light.

Thank you johnkamlax.  At least it is usable now.  I pretend I have a defective bulb in the VS button.  LOL

Hello, do you think Captain Sim will make an update that corrects that V/S error?
The solution that John kindly provided is an alternative but I prefer to wait for MSFS2020 to fix the problem that occurred in the last update that deteriorated the V/S of the B777-200.
Thank you

Where do I find that in the Steam Store version of Microsoft Flight Simulator? I don't have that file directory. I'd like to make this fix work as I also have the v/s problem now following SU14

B777-300ER on XBOX S Platform.

*V/S is not working.

*A/T can be armed/disarmed but A/T button is not working! >:(
