I agree the key word is PROGRESSIVE that way they slow it down and give
you step by step to each intersection or to the next segment of their
intended route to or from a runway.

| Subject: | Re: Cabin Pressure |
Hi John,
You raise interesting points. The argument can be readily
settled, since aircraft altimeters are very precise
instruments for measuring pressure. For the test,
one takes an additional altimeter on board on the aircraft.
It is not connected to anything. That altimeter is
calibrated on the ground, before start of the engine, so that
it reads exactly the same as the panel mounted altimeter.
Then one takes off and records in flight whether
the surplus altimeter reads higher or lower than the panel
mounted altimeter. If the surplus altimeter reads lower
than the panel mounted altimeter, then cabin pressure
is higher than the pressure in the static line, and conversely.
BTW, I was a bit bold in saying "always" about lower cabin
pressure. This does not apply to pressurized aircraft, and
there may be particular designs where it does not hold.
But it seems correct for the type of aircraft we are concerned
with here.
Happy flying,
Klaus
