What's the pitch parameter meaning?

error = ARMAVLINK_MissionItemUtils_CreateMavlinkTakeoffMissionItem(&item, home.coordinate.latitude, home.coordinate.longitude, takeoffhight.intValue,[self theangle:yaw1],0);

I give 0 to pitch. But I don’t know the meaning for pitch? It’s camera’s angle ? Or flying speed to raise up? And what’s the unit for the parameter?



The pitch parameter is described here (if you search for MAV_CMD_NAV_TAKEOFF, you’ll find the mavlink command description).
So it is: “Minimum pitch (if airspeed sensor present), desired pitch without sensor [rad]”.

In FreeFlight, they always send 0.
Hope this helps,


Thank you very much.
