Hi all,
Reading the posting on T&B's vs. TC has prompted me to seek a bit of input
on my panel. I have a Europa with a vacuum powered standard 6 pack. It had
always been my intention to upgrade to a glass panel once I thought that the
technology was mature. Well at 450 hours my vacuum pump is making sad
noises so I have to think about doing something soon.
My current setup has a vacuum warning light and a Navaids in place of a TC.
My initial thought was to purchase either a Grand Rapids or Dynon EFIS D100
and add to my panel a T&B, ASI, Altimeter and a TruTrack wing leveler, but
now I am starting to think of being a bit more conventional.
My current thinking is to have a standard 6 pac layout with a Dynon D10 in
the place of the AH, a 2.25 T&B, a Digitrack in the place of the DG. The
ASI, altimeter, and VSI's would be in the conventional places.
Design thoughts:
- Ebus feeding the D10 & T&B
- Dynon battery back up in case a total power failure
- TruTrack in case of a D10 failure
- T&B, compass in case of failure of the TruTrack
- Conventional /familiar panel layout for IMC work
Open items:
- Is there any failure modes of the D10 that other than "blank screen"
- Same for the TruTrack
- Is there a failure mode that would force me to arbitrate who is "telling
the truth"
I know that my thoughts and questions require speculative answers, but I
would appreciate some input from the forum
Paul

Hello Paul
"I know that my thoughts and questions require speculative answers, but I
would appreciate some input from the forum"
For what its worth here is what I am doing for my VFR Europa:
****SIRS Compass
****Winter ASI
****Dynon D10A primarily for AH, Turn rate, DG and VSI (along with Vario)
and ball (along with illuminated mechanical ball)
****Sensitive TSOed Altimeter
****Ilec Vario with 1 second and 3 second switch, and switch for Total
Energy or static
****Illuminated mechanical ball
****Panel mounted Garmin 296 that will probably mutilate and void the
warrenty but get a switch on control stick to allow easy toggle to panel
page
I had a 1948 Cessna 170 with a venturi, and old style AH with no inop
flag, and a electric turn and bank. After owning the plane for 15 years,
flying a good amount at night, not IFR rated and years since practice
partial panel I took off at night from Lebanin NH. Great visibility, high
cloud deck, blackest night I have ever experienced, no lights, no horizon
and at 200 feet I was fighting to keep from rolling upside down. I knew I
had plane trimmed for take off and something was really wrong. I knew
plane well and fooled hard when first got it. Let go of controls, unless
something aerodynamic changed, I knew plane would fly, then according to
AH was past 90 degrees, got worst case of spatial disorientation ever, but
Airspeed and climb was good in free flight mode, and I practiced my plan
long ago just to add right rudder enough to keep ball reasonable centered,
and make sure compass was not turning too fast. After 1000 feet AGL
determined that the AH failed, just when I needed it most. I took it apart
and the bearings decided at that very moment to drag up just a bit. There
is a lot to be said for a airplane that will fly like a big free flight
model, and for planes that are not inherent stable, Bobs idea of making
them that way is a good one.
Good luck
Ron P.

I think you're on the right track. You might want to consider TruTrak's
Pictoral Pilot or ADI Pilot instead of the Digitrack. They give you both an
instrument and AP in one unit, and both are IMHO easier to use than either a
T&B or TC.
You'd have to query Dynon/GRT/TruTrak about their take on failure modes. I
don't think there is enough operational experience with any of these units
to know what failure modes they will present. Murphy's Law hasn't been
repealed, so having to 'arbitrate truth' is always a possibility.
I'm planning on a GRT Sport, 2 axis ADI Pilot, ASI, Altimeter, and compass.
If the Sport and ADI disagree, I figure the Altimeter, ASI and Compass will
help me decide which is correct. Chances of both failing on one flight are
so slim I'm not even bothering with a third unit (same philosophy as a
traditional six-pack). If you stick with the 2.25 T&B, you'll have a tie
breaker.
That's my 2 cents...
