Which variables can I use to read your custom variables Black Square?

I cannot find a way to read if IAS or DES mode is active using SimVars.

I am reading A:AUTOPILOT FLIGHT LEVEL CHANGE, Bool to turn the 'green light' on for either the IAS or DES switch. Currently it turns both lights on when either mode is activated.

How can I 'read' which mode is active?

I can use RPN scripts but I cannot write them myself.

Thank you

That's what the (A:INDICATED ALTITUDE:1, FEET) 250 - (A:AUTOPILOT ALTITUDE LOCK VAR:1, FEET) < and... sections of the code above is meant to do. It simply looks at whether the preselected altitude is commanding a climb or descent from the current altitude.

I thought so but adding it as a Script to the entry field doesn't work and I cannot figure out why. I use something similar to detect if 100 or 1000 ft is selected for the altitude dial in another profile, that uses this script.

but if I use your RPN code, it doesn't detect between IAS (IASP) or DES.

I will ask on the AAO forum and see if Lorby can help too. Thank you

@Black-Square It is slowly coming together...

One question for you, how have you configured the V/S readout?

In the image below, 2.1 shows the A:Var AUTOPILOT VERTICAL HOLD VAR, Feet/minute
BUT this is only correctly displayed when V/S mode is active.

In reverse, when the ALT mode is active, the ALT readout does not change on the Stream Deck profile but it does in the sim.

Q. When I turn the dial, I can see the VSpeed change in the sim cockpit but the correct value is ONLY displayed on the Stream Deck when V/S mode is active, why?

N.B.The Starship is the only aircraft where my profiles don't seem to work 'normally'.

For both of them, you could try this technique:

Vertical Speed Select:

(A:AUTOPILOT VERTICAL HOLD, bool) if{
    (AUTOPILOT VERTICAL HOLD VAR:1, feet per minute)
}
els{
    (L:bksq_VerticalSpeedPreselect_1, feet per minute)
}

Altitude Select:

(A:AUTOPILOT ALTITUDE LOCK, bool) if{
    (AUTOPILOT ALTITUDE LOCK VAR:1, feet)
}
els{
    (L:bksq_AltitudePreselect_1, feet)
}

I'm not sure why that should be necessary for the selected altitude, but if it works, it works.

I'm also looking into getting data out of the starship, but for a different purpose: I want to use the WinWing MCDU or even a self-made CDU (the button-layout transfer from the MCDU to the Starship-CDU is way less intuitive than I thought) to interact with the starship CDU.
Best case, this includes the display of the Starship CDU being mirrored on the device.
I am using Mobiflight for this, so I need the data that is on screen in plain text form, including color information.

Is there any way to get that data? Or does it require an update of the Starship?

Black Square

@SaabFAN86 I have no idea what format that text and color information is supposed to be presented in, nor how to get it to you. Can you give me an idea of how these other units work? I suspect this is not something that's possible from the JavaScript context, but I will do it if it's remotely possible, or send you a custom solution if it's not something I want to include for all users.

@Black-Square Thank you so much for sharing this code.
I still couldn't get this to work as as a script in Stream Deck software but I was able to get both dial readouts populated using the LVars (as you originally suggested). Thank you.

@Black-Square I can't say exactly, how other planes provide this data. But from a cursory reading of the python scripts responsible for getting the data from the airplanes, parsing it and then sending it to Mobiflight, it seems that Websocket is commonly used to get the data. After that, it's parsed in the appropriate manner and then transmitted to the external Hardware.
With that in mind, I guess, a JSON-String that is pushed to this script through a Websocket-Connection, could be all that's needed to get the data to Mobiflight.
