Does AC support MAV_CMD_DO_FLIGHTTERMINATION?

Hi, does anyone know if ArduCopter supports the MAV_CMD_DO_FLIGHTTERMINATION message and what actions it does, when receiving the command? I am working on a flight termination system (FTS) based on EASAs MOC Light-UAS.2511 document and would like to use mavlink if I can to stop the motors immediately.

It supports that command since version 3.3 (2015)
You need to enable advanced_failsafe.
Or set param1 to 0.5 to disarm motors without advanced failsafe.
