Ahhhhhhhhhhh..... Rats!

Sorry..

Open the Alt static, THEN see if closing the airvent affects the
VSI..

If it momentarily swings positive, it could indicate a neg pressure
in the cabin..

Just a thought...

Sorry my first was not complete..

Dave,

I have signed up !

About the only instrument that I have not overhauled in this Archer is
the
VSI.
It reads horribly optimistic, like, I have the only Archer ever built
that
climbs on the plains here at 1200 FPM.
If I really try, I can make 1500 FPM :-)

I have to admit that I don't know much about the operation of a VSI
appertaining to an Archer :-(
I can't get my head round it at the moment, but could the slight
negative
pressure in the cabin affect the VSI ?

Hi Roy!

I second this.

That group has the most knowledgeable group on Cherokees bar none!
Newbees to seasoned AME's, and they all LOVE their Cherokees!

I think this discussion is closing in on UR prob, SOMETHING is
greating a vacuum in your cabin, and the cold air is roaring in to
replace the air being sucked out "somewhere"

How does the VSI respond to quickly closing the vent?

As to why the "left side vs right side"..scratching my bean on that
part...

As far as I can tell their is no draft coming out of the fine mesh
plank
vent on the pilots side.

That is so weird. Is there something blocking *that* opening? I
just
can't imagine what's causing that kind of strong air-flow.

The Cherokee Chat is the Cherokee Pilot's Association on-line chat
room. You've got to be a member, but it's worth every penny to
join,
and then some. See them he http://www.piperowner.com/

With over 4000 Cherokee owners in the organization, you can always
count on getting an answer on ANY Cherokee question you might have.
And they have the BEST fly-in of the year. See info on that he
http://cherokeeflyin.com/

We've attended the last four, and intend to go again this year.
