 Posted: Wed Jun 20, 2007 5:24 am Post subject: Instrument panel update- |
 |
|
I'm going to provide some info regarding our recent update and learning
experience in converting our Glastar from a steam gauge based VFR
machine to an IFR capable glass panel machine. This experience has
been extremely valuable in preparation for the instrument panel I plan
to build for my RV-10.
Background. My dad and I built our Glastar and flew it May of '99,
instrumentation was essentially all second hand steam gauges, a KT76
transponder and a Garmin 250xl com/gps. We flew this until the summer
of 2006, at which time we began the planning for our new panel. The
goal was to make an IFR comfortable and safe plane.
Here's what went in: Garmin 530 nav,com,gps +GI-106A CDI/OBS,
Garmin 340 audio panel, Garmin 327
transponder,
Dynon D-100 EFIS
Here's what we re-used: Garmin 250 XL com-gps, Navaid single axis
autopilot
At this point everything is working very well, However, many items
took some digging to uncover and resolve the issues.
See photo attached of our new panel.
Lessons Learned:
1) Wet compass: We wanted the compass to be panel mounted, not up on
top of the glare shield, and in the old panel it worked fine. However,
in the new panel the compass did not work at all, no adjustments to the
compensation magnets would bring the compass in line. Ultimate
problem: residual magnetism in the spiral steel wire in the scat tube
that fed the eyeball vent right near the compass. Using a gauss-o-meter
I sniffed out the magnetism in the scat tube and ultimately changed the
scat tube to a type that uses a poly-plastic helic coil. (available from
McMaster-Carr). Now the compass works.
2) Navaid autopilot wouldn't listen to the Garmin 530, however it
worked fine with the Garmin 250xl: Solution: One of the RS-232
settings that is selectable in the Garmin 530 is called "aviation data
format-no altitude" this is the one that the Navaid autopilot needs, it
cannot accept aviation data with altitude.
3) Limitation of the Garmin 530's RS-232 selectable ports: ONLY one
may be set up in the aviation data format. If you have multiple
devices which need this format you may have a problem. I ran into
this with the Dynon and the Navaid autopilot, since both need aviation
data format and the Navaid device cannot accept the data with altitude
in it, I cannot see the GPS reported altitude on the Dynon's HSI
screen. (minor detail, but annoying)
4) The Dynon's new HSI split screen software update. Awesome
for en route procedures but the thickness of the CDI line presented on
the HSI is just too fat to shoot a really nice ILS approach. I know
the GPS mode is for reference only and I'm going to get flamed for this,
but I'm just observing that the representation on the glass panel is not
as good as the analog CDI needle.
5) Antenna cable connections: The new antennas we added for the
panel update all had Mil spec crimp-on BNC style connectors, assemble
with the real crimp tooling, However, two of the old antennas, (com1
and transponder) had aftermarket style push on BNC connectors. (which
worked fine for 7 years) Well after all the shuffling around under the
instrument panel the shield termination on com1 became intermittent and
we had corresponding intermittent problems communicating on our fancy
new Garmin 530. Changed all connectors, problem resolved.
6) Static system leaks: passing the static system check was a
royal pain, our second hand steam gauge airspeed indicator had a static
leak around the temperature compensation knob. Tracking down static
leaks is a slow process!
7) Transponder: I always had trouble entering transponder codes
into our old KT76, I couldn't turn the knobs fast enough to keep up
with ATC. Well, if you haven't had the pleasure of a transponder
like the Garmin 327, it is huge, huge improvement. The direct entry of
numbers into the keypad let's me enter the numbers as ATC gives them to
me, awesome!
 Tied for #1 favorite thing on the new panel: The wind arrow and
the track triangle on the HSI. Wow, these two things dramatically
improved how I handle the plane.
More later.

Hi Bob,
wait until you upload the newest software coming out in the next weeks,
you can have your wind
vector on the main page (EFIS) , some new bugs on the compass as well,
glideslope directly in
the EFIS page, finally a VSI tape and a speed trend, all selectable one
by one.
See some of it here:

I'm patiently waiting, ( I check the update section of the Dynon website
daily) I think the movement of the altitude and airspeed info on to the
center-line of the atitude display will be a big improvement over its
current location at the top of the screen.
