I'm not aware that pitot pressure (which is directly related to
airspeed)

You're just trying to be nice, aren't you, CO?

:^)

We all know the fudog's memory failed him this time.

Well, I thought the bit about a VSI using pitot was a bit, um, well,
wrong.

One thing -- The pitot pressure isn't "directly related to airspeed",
(and we know you meant IAS, not TAS).

One, sorry didn't mean 'directly' in the physics/math sense, only that
it
was the input for an ASI (compared to static pressure of course)
An airspeed indicator gives you Indicated Air Speed. Q.E.D.

(A TAS indicator can also give you a TAS readout as it can apply a
correction
for the density altitude, but IAS is what you base your flying on (as
opposed to nav).

The differential pressure is really related to the airspeed *squared*.

Yes.
