• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

AP and EFIS data

I want to use simconnect to manage AP and EFIS data, but i can't find into simconnect documentation the "string" command code to read and write N1 button, CO button and all EFIS functions. I think that there aren't again into SDK. Can I hope that will be add with next upgrade of SDK???

According to Event IDs.html and Simulation Variables.html from SDK SP1:

There is a key event id AP_N1_HOLD used to engage Autopilot N1 control at current percentage. There are also events to set this percentage: AP_N1_REF_INC/AP_N1_REF_DEC and AP_N1_REF_SET (although this one is not documented).

However I don't see any simulation variables for it. Maybe AUTOPILOT RPM HOLD VAR would do the job ?
 
Exactly there is no simulation variable to read the status of N1 button. AP_N1_HOLD is an event and i can use this only to set the AP function.
About CO button AUTOPILOT RPM HOLD VAR you can have back the status of speed button when you have selected the mach display, but not refer to this variable to know the speed display status.
About EFIS there is nothing ( read and write ).
I though that the SDK would have provide the possibility to write and read all the aircraft function that we can select with the mouse, but at the moment i have seen ( unfortunaly ), that there aren't many parameter and so is not possyble to interface an hardware with all its functions, because are not supported by the SDK.
I hope that the microsoft team that have developed the SDK can read this thread and can complete the SDK with all aircraft operative mode in the next SDK upgrade.

I just checked in the source of default 737-800 gauges :

AUTOPILOT RPM HOLD gives you the status of N1 hold
AUTOPILOT RPM HOLD VAR is the N1 hold value (0.0 if autothrottle is not engaged)
