I am a bit confused about pressures in and around an aircraft.
Inside the cabin we have a static pressure, since we assume the air is standing still. (I know it's not, due to the Environmental Control system, but let's ignore that).
Outide the aircraft we have the static pressure = p ambient, and the dynamic pressure, summed up to the total pressure.
My question is. When we have a rapid decompression, which pressure from the outside is the one that matters (the one that decides the flow)? The total, the static or the dynamic?
Thanks for your input
