Normal PSI in Duct pressure at FL450 (45,000') is 19 to 22psi, it =aries with Density Altitude and Temperature slightly. Mike indicated that Gulfstream does not like the term "Buffet&quo=; or "Vibration" they use the term "TRIM Variance" 4 14/0 if the exhausted air from pylon precooler air modulation valve w=s not equal to both L/H and R/H the air is disrupted over the tail section=of the aircraft Causing a TRIM VARIANCE. I informed Mike that we had to change the Gasket on L/H anticipator an= found a Loose Temp sensor in Left Pylon, and we changed the R/H pylon Ant=ciptor gasket as a precautionary measure. EFTA_R1_01559878 EFTA02456555  Now that Bleed system Duct pressure is tight and equal, Mike feels the=aircraft is operating at factory specs, Depending on pressurization Bleed system requirements, the Duct pressu=e will vary when 12th stage bleed valve opens for decent. during climb the=duct pressure can read as high as 40psi, since the HP Bleed valve located =n each engine is set to modulate exhausted air at 40PSI max into the cabin=. if air was blowing by the Anticipator gasket, this effects the amount =f air into the cabin, since the Anticipator is anticipating the 400 degree=air, and adjust the HP regulator valve accordingly. We have changed Both HP Regulator valves about a year ago,. so they ar= good on both engines. Equal temps and PSI on the panel in Radio rack are important informati=n, for smooth ops. thx Larry please note The information contained in this communication is confidential, may be attorney-client privileged, may constitute inside information, and is intended only for the use of the addressee.
