when changing AUTOPILOT FLIGHT LEVEL CHANGE , MSFS has a bug setting Airspeed to zero. You willneed to correct that for it to work.

No local variable needed for it, there is already a Variable telling you the state of the Autothrottle switch: LOCAL:MULTIPANEL_AUTOTHROTTLE (0 or 1)

There should be a LVAR that tells you if they are on or off
