The Pitot Pressure from the Pitot Tube is a combination of Static
and RAM pressure. The bellows inside the airspeed indicator
uses the ambient static pressure from the static port to cancel
out the static component from the Pitot Tube leaving only the RAM
component to move the airspeed needle.

Of course...exactly...not rocket science after all...

Not even close. Moore is making the same dumbass claim as Knoyle.

The sole reason for using a static port is so the guts can be removed from
the pitot tube, in order to improve reliability. A pitot port produces no
static pressure datum.

Perhaps this will help:

Hang on here a second now Jim, you still need two samples. As Dan
says you need 'static pressure' to read the altitude from and you
need 'pitot pressure' (ram air pressure) as well as the static
pressure to derive the airspeed reading from. Sounds like you're
saying that you can read 'both' from just the 'ram air pressure'
alone. Or did I misunderstand you?

Jim has finally figued out what a pitot tube is, but somehow he still wants
to be correct in his archive troll. It is a great paradox.


I know...ain't life a bitch John
