[simpits-tech] Mask pressure - a ballpark

[Ben Jones]

Brian,

For whats it's worth i think your bang on, with the passive and active 
breathing.

When i got to fly in a mil aircraft ( Passenger with stick time )  2 weeks 
ago with mask on, i cant give you a figure when the extra pressure kicked in 
( i was too busy recovering from a botched manovures) but for the inital 2 
breaths it really well  F*****D with my breathing.

The other thing thats anoying is when breathing normally the valve kicking 
in and out .

Anyho , i'm going out for beers this weekend guy's ill ask the questions oo.

Ben
