Very interesting email that gulfstream tech support sent regarding pack temp=rature example aircraft in the Second attachment.

We we're flying in air temperatures +12° warmer than ISA during this is=ue,.

Note the photo I took during this event our pac out the temperatures were 61=and 72 degrees„ Temps should be 35 degrees to 41depending on outside air temperature / ISA

ISA = International "standard atmospheric temperature" all performance is b=sed on ISA temps
