Some time ago I came across this avsim forum posting regarding accessing the status of the WPT, TERM, INTEG, MSG, APR, TERR_WRN, TERR_CAUT, TRAFFIC indicators for a GTN installation.

It describes a method for extracting this information from an undocumented dataref.
This information could be useful for building your own hardware annunciator panel (which I am doing) or integrating this information into an existing instrument ( Garmin G5 ...!)

Re: ACCESSING REALITY XP GTN ANNUNCIATOR "DISCRETES"
The G5 is already using a few of these, but the amount of data is limited. There's no CDI scale data available except for TERM.
