Something strange happened more times with ASV: when on final, about 100 ft, autopilot not engaged, I get a sudden rudder and ailerons half-way deflection (about 60-70%) to one side, the airplane banks and it's difficult to get control over it.If I close ASV, cancel weather conditions and retry the approach, all is normal.Has this something to do with a kind of shear during short final?ThanksJames

Hi,Could have been wake turbulence that has been posted about.Could have been a downdraft. Have you installed SU2? VAS on landings was one of the fixes!!Please let us know!Hope this helps,JimActiveSky Sales and Supporthttp://www.hifisim.com/images/asv_dev_team.jpg http://www.hifisim.com/images/asv_proud_supporter.jpg

Thanks Jim, I wanted to install SU2 final release (not that I don't want to help in beta-testing :-)), but I will install the beta and see if it still happens.Regards,James
