Vs_state needs to be declared as a global variable (ie accessible throughout the whole code), not as a local variable (only in the function) In Lua the « scope » (read visibility) of a variable is determined by the location of the first occurrence of a variable in the code. If it’s declared or used ...

I am afraid that only commands can be used in the JSON file. But your datarefs can probably be replaced by the adequate XPl command instead, since the action you seem want to achieve is to set the parking brake, correct? { "name": "Parking Brake", "minor_cw_cmd": "...

“Hardcoded” is not really the term here IMHO. Merely “coded” instead, that means that you have access to the Lua code and this code can be amended/modified to suit your needs. Just a reminder: most of the instruments found on the Airmanager online store are freeware and made by the community. Meanin...

First your request seems a bit weird if I may… An ILS indicator is perfectly able to perform as VOR only if tuned to a VOR station. The GS needle will stay horizontal that’s it. For this reason, in real life the normal main indicator is the ILS on NAV1 and a (cheaper) VOR hooked on NAV2 as a backup,...

Sometimes reinventing the wheel is not the best solutions.
There is open source motion platform software available on the Internet, tested and proved, which is the most important part. High speed and powerful actuators can hurt people really bad if not properly setup and used, never forget that.

I don't have the Toliss nor FFA for XP12, only XP11 so I cannot test it, sorry

On the Toliss A321 XP11 there is a possibilty to enable the FMGC1 or 2 failure, but the indicator lights don't come on on the MCDU and I couldn't find any dataref about it neither

The main usage is when either one the FMGEC computer is failed or in a case of a Database discrepancy between the two is detected.
The IND indicator would appear then.
Doubt that the failure has been implemented in FFA or Tolis though.

I think the Toliss A319 doesn't provide FMGS Mode, as I don't see any Mode selector in the cockpit (each single MCDU can be shutdown, however the other doesn't forward the SINGLE MODE or INDEPENDENT status) : (*) https://siminnovations.com/forums/download/file.php?id=11527&t=1 *Note : this figu...

Nope, sorry. Kinda got frustrated with the gear failure impossible to set so I let the file ina WIP stage. Was in 2017 and FSX was still there. Probably should have a look at it again with MSFS ans Xplane, if (that's a big IF) I still can find the source, as due to a nasty HDD crash a few years back...

Found this on Xplane.org Instrument Maker A small utility to create the basic graphics elements for gauges, such as compass rose, horizontal scale, airspeed indicator. Don't be fooled though, it will not create the gauge for you, but can be a time saver for creating part of the png graphics ressourc...
