| Subject: | CJ6 Heading Adjustments |
Seeking info on how to accurately set up the Heading sensor/Flux valve in the CJ6.
After turning on the Gyros then syncing the heading the resultant displayed heading
is close to that displayed on the mag compass. If I then line up precisely
on Rwy hdg (and re synch) I have around a 7-9 degree heading error. Can this
be "biased' out ? If so whats the process How and on what ?

I have the same question. My CJ RMI had been spot on for 6 years. All of a
suddenly it is 180 degrees out on most flights and on rare occasions (very
rare ) it will be accurate. More wrong that right. Yes I know, who uses the
RMI?? Well, not much but I like EVERYTHING working in my airplanes! A
working airplane us a happy airplane.

When was the last time the your runway heading was re-identified? I
believe this is required every ten years for licensed airports but doubt it
is done for my small town runway. And perhaps yours? I actually laid out a
compass rose for ours about 24 years ago which of course by now is currently
useless.
In any case whether the runway headings are currently correct or not is kind
of a moot point at this time. They will be wrong next year!
The North Pole (that has lived in Canada for some centuries) has decided to
move to Russia (actually Siberia!). It is on the way at breakneck speed (in
historical terms) and nobody knows why! Some scientists are suggesting
changes to the flow of liquid iron some hundreds of miles below our feet.
I believe you could find a more intelligent discussion of this phenomena at
NOAA or National Geographic or?.
If you decide to make adjustments to your heading indication it is a
relatively simple process (for a qualified A&P). The primary unit, whether
it is referred to as a flux gate, or whatever, is in fact a master compass
that is adjusted in exactly the same manner as any other aircraft magnetic
compass.
In early CJ's it is located inside the LH wing close to the tip. In later
models in the aft fuselage RH side just fwd. of the horiz. stab.

Walt

The True heading hasent changed :) so applying the latest Mag var should result
in an acceptable mag heading. In my part of the world the variation drift is
pretty sedate.
