Hi, I'm looking for a command to "press" the ALT button on the transponder (GNS-Version). DataRef came up blank, at least I didn't find a way to change the mode. I'm ok with a lua-solution.
I also have a question regarding the GPSS-Roll-Steering Button (GPSS/HDG). Is it intended/realistic behaviour, that I can't change it and don't have an indication, unless I already have the AP active in HDG-mode?
Lastly, GPSS behaviour: If you follow a flight plan and do a "direct-to", the GPSS turns even before your "accept" by pressing the "enter" button. Is that correct?
