I have been trying to get the autoland feature working for a couple of weeks now to no avail? The first time I made a flight plan with several waypoints and then a final LAND command where the plane would reach and then stall, on the second attempt I read the wiki and followed the instructions there, which consisted of using two LAND commands and adding a break alt, radius and cut alt commands, athough in mission planner the colomns are not marked as they are in the wiki? they are just blank boxes... But using the same boxes as in the wiki I filled in the other parameters and started another mission this time the plane would stop at the waypoint before the first land waypoint which was a few hundred meters away, and just drift off without throttle only remaining stabilized until enough airspeed had dropped away and then go into a flat spin. What am I missing?

Ok, I still seem to have trouble with autolanding or even dropping altitude? I tried to drop it into wind over say 500m from 100 dropping by 20m at each waypoint till 40m just to make a low pass.. But by the time it was around 70m it went into a flat spin and I had to switch into manual to recover it.. It seems to hold cut the throttle in order to drop altitude but doesn`t pitch down to keep airspeed, it just uses the elevator to hold a level attitude until all airspeed is gone and forces the aircraft to stall? I have the APM2.5 and an airspeed sensor
I've been looking at code and I cannot see how it would handle two LAND commands. It seems to work that you set the landing coordinates and altitude where you want to land, and when the plane is within 3m Alt or 2 secs to this location it cuts throttle and makes sure the plane does not roll. The pitch is held positive if you have no airspeed sensor.
O.K so no one has tried the autoland feature with success? Surely someone must have tried it?
