PZL compass repair

Fellas,

I highly recommend a Hamilton vertical card compass, easily swung and
never a leak. I also like the planform display. I've given up on the
old style compass, always leaking and not legal to fix or refill
yourself. They're pricey, but once you buy it, you're done messing with
compasses.

Anubody ever had problems with a Hamilton?

Yes, it wouldn't rotate more than about 120 degrees. Bought a new Airpath,
used solely as a backup should the GPS and moving map fail

A number of reports where the needle stuck and you have to tap the
instruments to free it. I have an Airpath 2300 but can't tell you the
last time I actually looked at it.

Hi Jim - I have had a Hamilton and replaced it with a PZL.
The Hamilton is, because of its design, very sensitive to
pitch attitude, and consequently quite inaccurate. This is
especially true at higher lattitudes with steeper dip. The
problem is that mechanically the sensing element can't
really stay level.

Pick a point on the horizon heading East or West. Note
the exact compass reading at 45 knots. Now stabilize the
airspeed at 110 knots and see what the compass reads.

It does look nice though !
Best Regards, Dave

Dave,

That's interesting, I'll give it a try. I'm at a higher latitude and I
do like to have a working compass just in case the un-thinkable happens
someday. Might have to put one of my old, leaky whiskey units back in.
