| Subject: | Tailplane issue? |
--> Europa-List message posted by: "Roger Mills" <Roger.Mills@btinternet.com>
Paul,
I had a similar problem which I found to be due to slight mis-alignment
of the TP12? drive pins with the TP13? sockets - it doesn't take much to
produce the symptoms you describe. The fact that things tighten up in
the last 5mm is the clue!
Check the alignment of the pins by pushing some tightly fitting tube
over them and sighting against the toque tube and socket positions on
the tailplane. You may need to judiciously tweak the pin alignment and
ensure the TP13 sockets are greased properly - but, whatever, you should
not be using heavy handed forces in assembly or disassembly.

Hi all,
I am interested in anyone's experience with tight tail planes. The
problem I am having is the tail planes fit snuggly until the last 5mm
and them need to be pushed home hard. The only way I can get them off
is to pry them off with a screw driver which doesn't do the paint much
good. I'd like some idea on what I can to improve the situation.

Having re-read my reply and the question I was not responding to the right
question.
The problem where the tail plane is hard toinsert in the last 5 mm or so is
probably because the 2 pins that insert into the ali bushes are not parallel
with the torque tube. We also had that issue too. That was NOT cured by
squeezing in the vice. That was cured by bending the pins until they were
parallel with the torque tube and rebonding the little bushes back into the
tailplane. The tail plane now slides on and off easily.
Cheers

Quite right, though each manufacturer of the experimental EFISi has their own ideas
on
symbol weight, color, and font. As you move up to the heavy iron EFIS, things
seem to
standardize more to something more high-contrast and bold sans-serif than BMA and
Dynon. But human factors engineering is notoriously non-obvious.
Dynon's product is promising and certainly inexpensive, but I think they were caught
off guard by the intense engineering effort required for something as mission-critical
as
an EFIS. It also strikes me that the D-10 and the EFIS-lite will have only a limited
market
as back-up instruments. Their small size eliminates the biggest human factors
benefit of
a glass EFIS - better information presentation in a comfortably sized display.
It is unlikely
that many steam gauges will remain in a panel that uses an EFIS ( take a look at
Ira's website ),
whether retrofit or brand new; the panel will ultimately be designed around the
EFIS.
BMA's and GRT's approaches are ultimately better because they've realized this
and
used large screens from the start. I give the nod to GRT because they've substantially
increased the the size of the EFIS display over BMA, which will be better for those
without
20/10 vision (i.e., me).
Dynon may have a good product, but in my opinion if they don't follow up IMMEDIATELY
with a
GRT-sized display at around $3K their long-term future will be in doubt.
GRT suprised everybody with a well thought out and configurable product that is
far better
suited for new panels, and, to their credit, they didn't even talk about until
they were sure it would work.
The shakeout begins.

...thats right Shaun! GRT have just about the right size for the europa
panel. Using the BMA efis would need i believe an extension in panel height.

One of our group has just been in contact with BMA concerning the apparent
lack of warranty outside the US (see their terms and conditions on the web
site). They say this is an oversight they were unaware of and it will be
changed. So maybe the BMA is back on the shopping list!
