Apologies if this has already been asked before, but I have been trying to attempt an autonomous landing with an APM 2.5 in a Skywalker. The aircraft navigates perfectly fine all the way up until the aircraft aims for the landing waypoint. At this point it seems that the aircraft has a lot of trouble losing altitude.
I've attached a screen shot of the tuning window below. During regular waypoint navigation, the aircraft has no problem dropping 100 ft over 10 seconds. However, as shown below, when navigating to the landing waypoint, the aircraft only drops six ft over a period of 10 seconds. The blue line on the graph below shows altitude with the red line showing the target altitude. The graph ends about 3 seconds out from the landing point.
I also tried approaching the landing point from the opposite direction but still had the same results. Is there any parameter controlling the descent rate during an autonomous landing. Any help would be really appreciated.
