But can be remedied by upgrade of FGC computers from our current -905 to -906 computers., system operates normal. Our GIV has first generation SPZ8000 autopilot, GIVSP has SPZ8400 and GV had SPZ8800., I plan test flight in Helicopter Ilam tomorrow for blade tracking., Possible test flight for vibration in GIV around 5pm, depends how heli flight goes,. I'll take several Gulfstream Techs to experience our buffet/vibration for opinions„ Thx Larry Sent from my iPhone EFTA00666885
