For all i know Ardupilot in Auto mode, calculates to get exactly to certain point in certain height.
I got an issue that when i want to decent with the fastest ground speed using WPNAV_SPEED, the copter descent in slow ground speed (half of WPNAV_SPEED) and slow decent rate (WPNAV_SPEED_DN)
To put in nutshell, what is the best way to decent using WPNAV_SPEED_DN (fasest decent rate) and WPNAV_SPEED (fastest ground speed).
Thanks for your attention. I’m looking forward to your reply.
