Deompression Our A/C is designed to operate at very
high
altitudes, the A/C cruising altitude is
approximately
37,000 feet. There is not enough oxygen in
the air
at this altitude therefore our A/C is
designed to pull
oxygen together & compress it into the
cabin
giving enough oxygen in the cabin air so
that crew
& passenger can function normally. If this
system is
disrupted in any way then decompression
will
occur. Decompression is when the cabin
pressure
equalises to the outside pressure.
, Slow Decompression This is a gradual loss of cabin pressure
which can
take more than 10 seconds for the cabin
pressure
to equalise with the outside pressure.
Examples of
this could be a hissing door seal or a
cracked
window.
Rapid Decompression This is when the cabin pressure is lost
suddenly
which can happen in less than 10 seconds
for the
pressure to equalise to the outside
pressure. An
example of this would be a full door blow
out. A
big danger in this situation is 'Lack of self
criticism'
which is caused by sudden lack of oxygen
to the
brain.
