Most simple way to get the vehicle to certain position

#1

Hi all.

I’ve been trying to control vehicles (fixed wing) with original telemetry devices, and wondering what is the simplest command to make a vehicle go to a certain position (lat, lon, alt).
MAV_CMD_NAV_LOITER_UNLIM seems good to me. Does the vehicle move to the designated position immediately when received this command? Or are there any better MAVLink command?

Thanks.
