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

Jim is likley talking about a pitot tube assembly which contains static
ports along the side of the tube (P1, S1 and S2 ports as they're commonly
referred to). The fact that you don't get it surprises no one, splaps boy.
I'm sure Gord is just humoring you.

Read page 5 very closely, splappy:

Actually, the discussion was about the term "Total" as the
label above one of the fittings on an air data computer reads.
In his usual (dishonest) style, Splaps has snipped important
info. His claim is that this fitting is connected to more than
one sensor. (WRONG)
This fitting is connected to only *one* pitot tube. (either type)
The term "Total" in this case refers to altitude pressure plus
impact pressure.
The other fitting on the ADC reads "Static" and is connected to
static ports (either type) which detect altitude pressure *only*.
This altitude pressure gives the altitude and is also used to
remove that irrelevant altitude pressure from "Total" resulting in
airspeed. Computers are good at stuff like that. :-)

Since Splaps seems to be ignoring it, here's something from
a couple days ago:
"The obvious giveaway as to whether a modern aircraft utilizes the older
simple pitot tube or the newer pitot/static combined tube is the number
of tubes/probes installed on the aircraft. As I've stated before, the
727/757 and DC-10 have three standard simple pitot probes mounted
in the nose.
The static ports are flush mounted on both sides back by the fwd. cargo
door.
The two mounted up on the vertical stab. of a 727 or 737 for ELF are
the standard pitot tube.

On the other hand, the four probes mounted on the nose of a 737 or 747
and 767 are of the combined pitot/static port.

John, doesn't it just **** you off that, in spite of your warnings about
mud bees, Boeing chose to ignore you and utilize the simple pitot tubes
on the nose and flush mounted static ports on the sides of the 777 ???

When the Boeing Engineers aren't laughing at you they are ignoring you!"
