Thanks for the insight. So, it all depends on the pressure inside equalizing with the outside, and there is some time response.
I am curious about the pressure equalizing; I was asking myself why would there be any guarantee that the pressure inside the fuselage attains the static pressure of that altitude?
- assuming a solid box with air in it, in this case, a fully sealed box that is not like an aircraft where the rivets etc might not be air tight
- when there is some (not drastic) change in altitude, the difference in pressure is not large between the inside and outside of the box
- and it depends on the material of the box, which might alleviate some of the pressure differential (?)
By the way, you mentioned about certification. Would you happen to know what those tests involve?
Thanks. Great help.
