plogged Sock or dirt obstructed, if its fully blocked due to Ice it bypasses and you would hear ice pellets in system ,. I think could be dirty, New socks being installed now, . since gaspers is direct flow from ACM Air Cycle Machine,. if all gaspers are open, obvious low airflow, if we close all gaspers on one side,. we should be getting manifold PSI reading on gauge pressure at gasper if system is tight,.

if the mainfold pressure reading is different from what is actaullly coming out of the vents what could be the problem?

## I spoke to Tech ops,.

45,000 feet, Test flight aircraft report,. manifold pressure acceptable range is 20psi to 27psi,. single pack operation at 41,000 feet is 16 psi to 18psi we are reading 23psi on left and 26psi on right side manifold pressure, at FL450,. we are good here.

if Sock was freezing,. ice pellets like you heard on 8727 would be rolling down air ducts according to Gulfstream,. I am have socks changed as preventive Mx.

thx
