Every time I try and land my posky-pss aircraft, the spoilers seem to deploy then retract, as if the plane has touched down and but AP recognizes it is still in the air.There seems to be some conflict between the pss panel and the posky model can anyone help?

What merge are you using? I fly the merged Posky/PSS B777 on a regular base and don't have this problem.Also, be aware that any increase in N1 after touchdown will cause the spoilers to retract.

Actually, this problem is consistent with a number of merges I've found and tried around the forums. Currently I'm using a merge that someone else sent me, but this problem also exists with the posky_pss_777_merge.zipin the Avsim library. Also, as I land, my engines are idle. There is also a 'speedbrakes extended' alarm which go off, then disappears.
