This list is always subject to change
Since our AP runs independent from the sim AP you can no longer use the default K Events to trigger AP modes.
Our AP mode indicators are L-Vars while their triggers for AP modes and other peripheral buttons are H-Events, both of which the stock SimConnect has no access to.
External apps seem to be adding modules which would support LVars and HEvents. So ask the developer of your external binding application to add this feature.
For the AP variables like HDG, Alt preselect, VS you must use the K events with indexes. These should usually go to index “1”.
