Autoland stall in 10KT head winds

#1

Hi all in auto land plane does the cube use the airspeed sensor and the gps speed ?
i had a plane stall drop in 10KT winds ?
looking at the logs there was 10KT difference from Air speed to gps speed
is there a way to overcome this on windy days ( thats like 80% my flying days lol )

@jschall, can you please look at this?

We’re you using the airspeed sensor?

took another plane out today wind was from 9 to 15 KT tried 3 time auto land it goes to stall
the glide slope was spot on to the last 10m from land point 3 meters high its cutting the throttle to idle then stalls and falls
is there way to switch to gps speed 3 meters off the deck

Are you preheating your cube before flight so alt reading stays correct during flight

#6

yes 30 to 50 mins its cooking on the way to the field :smiley:

#7

do you have a lidar to determine the actual true height above ground?

#8

not on all my planes just the new UAV it has Garmin LIDAR-Lite v3HP**
i went out Tuesday no wind it landed better than me on the sticks lol
its only on 10KT+

Hi all
auto land fixed wing
LW20/C (100 m) or SF11C (120)
i can get my hands on LW20/C
which is better for auto land on fixed wing UAV
