View Full Version : What is this instrument?

Looking through ads on aso.com, I ran into this picture.
http://www.aso.com/aircraft/77810/panel-1.jpg

What is the instrument in the lower left of the panel underneath the
clock?

It looks a bit like a VSI, but the 0 point is at 12 o'clock instead of
9 o'clock, and it appears to have 3 indicator arms. Also, the scale
isn't symmetric, it runs from -5 to +12.

If it helps - the plane is a Cherokee 180.

Thanks,
Nathan

I think it's a G meter, but why you'd put one in a Cherokee is beyond me.
The arms indicate the limit positive and negative since it was last reset.

Without looking at the picture, I'd say it's a G-meter. One hand
measures instantaneous G load; the others stick at max plus and minus
until reset.

In a PA28, though? The owner must have wanted to plug a blank hole in
the panel.

G-meter? The three arms would be max positive, max negative, and current
reading. The -5 to +12 range sounds a bit excessive, though, especially
for a Cherokee :-)

Nathan,

It is a G meter. The numbers to the left side of the zero is negative
G's and the numbers to the right are positive G's.

I use mine to rate my landings :-))

It's a G Meter.. rather extreme for a Cherokee..

the pilot must of gotten tired of being bounced around in mountain
wave/rotor turbulence.. and he wanted to see what kind of punishment his
little bird could handle..

G meter.. steady state level flight.. or sitting still on the ground it will
measure 1G like it is right now.. looks like he's been "light", but not to
"zero G" and he's been heavy to 2G (60degreebanked turn?)

Maybe he uses it to record his students punishment of the runway on hard
landings..

Congratulations Nathan. I have never seen such unanimity on any
rec.aviation newsgroup!
