Hi,
While landing I had odd problem. It was a windy day, and I landed in FBWA as the aircraft was struggling against the wind in AUTO. Approach was good but at maybe a meter or less off the ground I pulled the stick back to flare, and it felt like the aircraft totally ignored me. Looking at the logs this is pretty much confirmed, I had airspeed of around 15m/s and you can see me command positive pitch but nothing from the aircraft.
No doubt related but during the decent from the mission while in FBWA a fairly bad pitch oscillation occured, I backed off the throttle and it stopped. The aircraft was fairly extensively autotuned but I feel the PTCH2SRV P and D are too high possibly ? I was thinking half P and D ?
PTCH2SRV_D,0.1707164
PTCH2SRV_FF,0
PTCH2SRV_I,0.05
PTCH2SRV_IMAX,3000
PTCH2SRV_P,2.276219
PTCH2SRV_RLL,1
PTCH2SRV_RMAX_DN,75
PTCH2SRV_RMAX_UP,75
PTCH2SRV_TCONST,0.45
Percentages are mission planner playback percentages, other figures are times.
62.4% 15:20:11 Launch.
82.0% 15:23:10 Pitch oscillation, between 0deg and -20deg, quite violent, around 2-3hz frequency
88.4% 15:24:01 Landed in FBWA
