I've searched around the forums, and been unable to find the answer to this, but does (>K:AP_PANEL_VS_HOLD) actually do anything? Regardless of the value of K:AP_VS_VAR_SET_ENGLISH, there doesn't seem to be a VS HOLD capability separate from AP_ALT_HOLD.Does anyone know why K:AP_PANEL_VS_HOLD exists? If it's not to command a V/S, is there some other purpose?Thanks,--Jon

>Does anyone know why K:AP_PANEL_VS_HOLD exists? If it's not to>command a V/S, is there some other purpose?I don't have a clue! I've never been able to get those events to work in either XML or C... The corresponding state variables never change bool value, even when using the keyboard control!Maybe there's an undocumented entry required in the aircraft.cfg file for VS_HOLD... (shrug)*:-*

Heh, thanks, Bill. I guess I'm not losing my mind after all. Back to the drawing board...--Jon
