RTL comes home at right altitude. FBW-A flies nice. so PID's ire not too bad.
When in AUTO, AP applies negative pitch, and would hit terrain.
WP altitude is 100 -"Verify Altitude" not checked in planner.
I see in the log that targetalt = 103 and targetaltd100=1,0285 (what is this value??)
Actual altitude is 73, and AP is still descending at -7 degree when going for first WP. - any idea of why ?

Andke, looking at your log, you have your airspeed set to 12 m/s but your plane only ever does 8-10 in auto, hence the drop.
i would try 2 things.
increase your throttle cruise, and lower your target airspeed.
your plane also makes no attempt to throttle up. is your throttle configured correctly?

Chris: thanks for help - I assume you had reasons to suspect airspeed related routines. Hope we see a fix soon.
Are you using an airspeed sensor?
