REFLECTOR: Reflector Digest, Vol 38, Issue 65 - Grand Rapids EFIS

I just spoke to the folks at GRT and they have 2 new options to consider for
the Horizon 1 EFIS. The high resolution screen announced at Sun 'n Fun is a
$400 upcharge and will be shipping in November. They have also just come out
with a new HX option incorporating a faster processor. This will support
full synthetic vision with 3D terrain. It is a $2,000 upcharge and will be
shipping in December or January. They hope to have one on display at
Oshkosh.
I am leaning toward going with the HX option with a backup Dynon EFIS. Has
anyone had any experience with Dynon?
Thanks,
Mark Riley

Scott,
I notice that GRT provided me with a 0-150 psi pressure transducer for the
oil system, which tends to suggest that 150 psi might be a reasonable
"proof" pressure for testing.
Regards,
Keith Hallsten

I'm pressure testing my new oil lines and cooling system(two coolers).
I ran it up to 90 psi a couple of hours ago to help chase down any
leaks. A friend of mine suggested 150 PSI as a good final test
pressure. Does that sound about right?

You would be surprised at how many emails the reflector gets of people
testing their mailer software. Invariably the subject contains "test"
in it, so I manually approve those.

Only 2.5 years as a cop. Before that I was a professional student/ and then
a lawyer for ten years in private/solo Estate Planning practice. But this
cop thing is waaaay fun. I still practice some law, but the cop things is
something I have always wanted to do and I figured if I didn't do it now (in
my mid 40's, I never would). My undergrad degree is in Criminal Justice,
but the year I graduated the City of Houston started a hire freeze which
lasted three years....so I continued in grad and then law school. At the
time I wanted to work for the Houston Police Department, now, I am thrilled
to be working in the City of Bellaire (a city completely surrounded by
Houston, twice the fun, half the PITA).
I am leaning towards some sort of guard since, for some reason I really like
toggle switches. But the investigation of majoring in minor things,
continues <g>
All the best,
Chris

Chris, I would use either good rockers, not toggels, or go with the switches
with the guards. The rockers are low profile and take a deliberate push to
activate. Toggels are just too easy to move by accident. Guarded switches
just look cool! My opinion.
By the way, how long have you been on the Job? I retired from Scottsdale, AZ

As most of y'all may know, my project is an all electric bird (Velocity SE)
with a rotary engine. Since if I loose power things get quite I am using
Bob Knuckls' duel alternator/duel battery set up. What I am curious about
is the switches in the cabin. Currently I have all the switches up high on
the panel a bit right of center towards the co-pilot position. I hope to
not have a passanger who would inadvertanlty flip a switch down and off,
HOWEVER, you never know what may get tangled or a stray move may flip a
switch. If my coil switch or primary injectors get switched off I will start
sweating. Also, I don't really mind the switches where they are, but I do
have a couple of other places I would like them, but I placed them here as
to minimize being bumped.
My question is what other options do I have to either guard against
accidental deactivation. I have purchased a couple of aviation locking
toggles from ebay, but they are kinda small and may not be up for the task
(but at $13.00 for twoI couldn't go too wrong...they may work for my coil
switch and primary fuel). The regular priced DPDT (for my contactors and
injectors) seem to start at close to $60.00 a piece...a bit much for my
police salary if other options will surfice.
I have also considered installing some of the switch guards you see in old
nuclear missle bunker movies that they would open to expose the firing
buttons for the big ol' missles. I considered installing them upside down
(which is really easy) so that they are on when the cover is closed thus
making the switch impossible to turn off by mistake. This seems really fool
proof, however, the guards, while cheap, are pretty big and do not look all
that, well, elligant.
Also, I was watching the Astronaut Farmer last night on PPV and saw the
little hard wire loops that where installed next to the switches on each
side of the individual switches in his space capsule and this reminded me of
the ones NASA used to use....maybe still do. Donno. These seem to be just
half circles that make grabbing the switch very deliberate and minimizes
potential knocks. Finally, it seems as if I have seen bars held in by
springs that lay across a series of switches to keep them in place.
What say ye? Insight? Wisdom? Warnings? Observations? WAG's?
Thanks.
All the best,
Chris Barber

Message-ID: <E1I9uP8-0001ME-00 at pop-savannah.atl.sa.earthlink.net>
Content-Type: text/plain; charset="us-ascii"
I recently bought the new adjustable seat back hinges from Velocity, but
have had difficulty getting them installed in a way that makes them operate
smoothly or freely. Understanding that they are designed not to mount
directly against the seat bottom and back pans (but instead with the seat
fabric and a little bit of foam trapped in between), we have tried using
shims to simulate the thickness of the fabric and foam. But even so, we
have still been unable to install them so that they operate smoothly and
freely or to allow the front seat backs to be easily folded down nearly on
top of the seat bottoms for easy ingress to the rear seats and for the easy
storage of bags behind the rear seats.
The basic problem seem to be the fact that the lower part of the seat backs,
where the hinges attach to the embedded hardpoints, are not parallel which
angles the two hinge axes and prevents them from being co-linear, as shown
in the photo below:
The angling also causes the seat tilt rod to bend and not operate smoothly.
The adjustable seat hinges seem like a good idea, but we have been unable to
install them properly.
The question is whether or not someone on the Reflector has been able to
successfully shim the hinges to allow the seat back to move smoothly and
easily through it's full range of tilt forward motion, and if so, how they
did it.
Any ideas or suggestions from people who have made them work would be
appreciated,
Thanks,
Bob Jackson

Chris,
Since my V is all electric also, I wanted a way to manage possible
inadvertent switching. I used AeroElectric as a guide for most of my wiring,
and then
made it fit my needs.
I put the 2 electric fuel pump switches up high on the pilot side of the
panel, above the Mixture control. You can't touch it with your hand on the
mixture, but they are close enough to be quick to reach if you need it.
I laid out my switches (toggles) at the bottom of the panel in the "normal"
place.
The far right is the dual ignition switch. I wired it so that either 1 is
on.. or the other (no off). I also made it so that one side of the switch
could
fail (from a burned contact or such) but the other side would still remain
operable. The only way for the idgnition switch to fail would be if it
totally
fell apart. If that switch gets bumped, it just switches to another ignition
system.
The next switches left are the 2 Battery Switches. Up is on, Down is off. at
that point you are getting right by my knee... I'm pretty sure I'd notice
something/someone that close. Still, you can turn one off and everything
will
still run. The 4th switch from the right is the "Master" It has a "hat" on
it so
that it is different from the rest.
I have my V set up so that: If you turn off the "Master".. everything is off
except Ignition. Fuel pumps, backup gauges and panel lights. That way, If I
have a smoke or wire problem I can shut down everything with one switch
except
critical engine stuff. (to shut off the rest, just turn the ignition key,
which
is hiding underneath the arm rest where it cannot be bumped)
The rest of the switches across the bottom are for the Pitot heat, Prop
controls, etc. My "emergency" switch placement is all switches up. That
will
switch from my starting ignition (down position) to the other, all batteries
on,
master on, prop fine, pumps on. etc.
As you know, it takes a lot of paper to fiddle with this stuff until you
rationalize a decent "end". :) Sure is fun though. I thought I'd work by
design
instead of by fix. At least that was the theory :0

I have some toggle switches in my panel that must be pulled out before
they can be flipped. That should protect against bumping.
