Are you stating that with a window blown out at FL510, the Global cabin only flies up at 800-1,000/min?

I'm not stating that you are wrong, but if it is true it is very difficult for me to comprehend.

Also, if it's correct, what is the big deal about a decompression at 510 in a Global? Jeez, if that's the case one would have plenty of time to go to the lav to sh1t oneself in comfort before trying to get a mask on!

That what I understand is the cabin's ROC is on the test--essentially another outflow value that simulates a window failure. There is a huge inflow of air from the ACMs. I can tell you, turn off a pack at F450, and you can't feel the change in pressure.

I'll check my info this week.

Galaxy, is it safe to assume that's done by analysis? It'd hate to think the Feds would make you actually test the loss of a window at 51k :eek:

tracer,

Let me get some details and confirm the test and it's results.

tdracer,

Spoke witha pilot familiar with the flight test protocol; yes, it's actually done at F510, but the cabin ROC is closer to 1,800-2,200 fpm when the simulated window is opened. I was off by an order of magnitude, I think.

Did five years on the B747-200 what a beautiful aeroplane!

After hearing the information gf shared with us, we need to know what gulfstream has to say about it.

They (bombardier( can use this information for marketing...
