I'm not flying yet, so I can't speak from experience!
I have installed the Dynon D100 EFIS and D120 EMS. The EFIS has a battery
backup, so if it all goes dark, I should have at least the flight
instruments.
I ave also a magnetic compass and ASI and Altimeter (both 2.25", so don't
take up much space).
Here in the UK we are limited to daytime/VFR anyway, so I always have the
option of looking outside to make sure I'm the right way up and above
ground.

My plane will fly in a year not yet determined. I'm planning to equip it for
night VFR and OTT. My current plan is to use a Dynon D100 as the primary
instrument, backed up by a lift reserve indicator, electric T&B, and GPS. My
thought is that if looking outside isn't enough in the circumstances, I
would maintain safe airspeed using the LRI, altitude using GPS, and wings
level from the T&B. It would be high stress flying!

I fly a 601XL with a Dynon D-180 on the left side of the panel and a Garmin
396 in the middle. I love everything about the setup (well, except the
price of the backup battery for the Dynon).
My mistake was in not putting a D-10A or some other form of attitude
indicator on the co-pilot's side. Motivated by a sad case of the "cheaps" I
assumed that the screen on the D-180 on the left would be big enough to
allow a pilot on the right side to use it. *Wrongo*. My pilot friends in
the right seat need something to look at. Sporty's backup AI would be an
option and it would give the "backup". But, for the difference in price
between the Sporty's AI and a separate D-10A the D-10A provides a much more
usuable picture with more information and independent backup that gives what
one person on this thread called "dispatch capability." (Assuming, I guess,
a separate pitot).
So, don't make my mistake. Put two screens in if you will ever have a pilot
in the right seat.

I have a Dynon D-100 and D-120. I also have installed a TruTrak Autopilot
that has a horizon and DG, this along with a small altimeter and ASI give m
a good backup. In addition the GPS can be of help. Is this overkill?
Probably. My main backup is this thing called a compass and a map.

This weeks EAA Hotline email had this. You do have to be an EAA member to get to

Q & A:
Question of the Week
Do you have a "release of liability" form for when you sell a homebuilt aircraft?
Answer:
Great timing! We have just posted a "hold harmless agreement" for you to use for
that very purpose. You must have it reviewed by an attorney before using it.
You can find the release on the EAA members only website.

| Subject: | Electrical question |
I think I already know that the answer to the following question is "NO" but there
are many of you guys out there who know more about electronics than me so
here goes.
I need to install an SPDT switch to select my right or left aux fuel pumps. The
EXP BUS power panel will provide the "on / off" switching for whichever pump
is selected by the SPDT switch. The problem is this...... the best area for the
switch would be centered directly above the fuel selector valve and in that
location, I have only 1/2" between the back of the panel and one of the fuel line
elbows on the valve. All of the 12VDC rated switches that I have found are
too bulky to fit in that restricted space. I have found several SPDT switches
rated for as much as 10 amps at 120VAC which would fit there easily but I remember
being told long ago that they will heat up too much if I use them for a
12VDC circuit.
Can an AC rated switch be used in this application? Bear in mind that we are talking
about boost pumps which are used for short periods of time and draw maybe
2 amps at 12VDC for a minute or two.
Okay all you electronics whizzes out there..... save a harmless lovable dentist
from himself.
Thanks,

| Subject: | Electrical question |
Any switch with an AC rating will have a DC rating - it is just a matter of
finding it. The reason a switch is rated lower for DC than AC AT THE SAME
VOLTAGE is because of the electrical arc formed when the switch is opened.
This is when a lot of the wear occurs. But in an AC circuit the voltage
drops to 0 as the voltage alternates (the "A" in AC) every 1/120 (60 Hz) or
1/100 (50 Hz) of a second. This extinguishes the arc. But you are switching
one tenth of 120 VAC so the arc is reduced.
Take a look at this article from Bob Nuckolls of AeroElectric fame (esp. the
chart at the top of page 2):
www.aeroelectric.com/articles/swtchrat.pdf
Here is the key quote:
"In a nutshell, 125 VAC ratings equate favorably and conservatively to 14
VDC ratings - as long as the switch has a healthy "snap" action . . . all
toggle switches and most rocker switches do. Just because the numbers
stamped on the side of the switch don't mention a DC capability doesn't mean
that the switch doesn't have one. Manufacturers are unable to put ALL of the
information from the chart onto the side of every product, the lettering
would be too small to read!"

It's not the steady current flow that causes problems when using AC
rated switches for DC circuits. It's the actual switching process.
Interrupting a DC current is harder on a switch contact than
interrupting AC current. That's why a switch with a 10A AC rating
usually has a much lower DC rating. Those 10A AC switches may work
for a 2A DC circuit but it would be nice if you can find out the DC
rating of those switches.

Hello All...
I am finally reaching the point of needing to purchase a spinner for
my 801 in preparation of making the cowl this summer. I tried
contacting UHS Spinners, but have been unable to get them to reply to my
queries.
For a 3 blade IVO magnum on an SAE 1 hub, what are the possible
options for purchase? Ideally, I'd like to purchase one which is
already cut out...
Any recommendations?
Thx...

Thanks for the responses regarding the DC rating of an AC rated switch.
Both relpies indicate that the problem point is the arcing that will
happen when the switch is opened or closed. That solved my dilemma. In
my proposed application the AC rated switch is a SPDT switch which will
be used to direct the 12VDC power to either the right or the left boost
pump (I have one facet pump mounted in each wing root next to the tank).
This "fuel pump selector switch" is fed by the fuel pump switch on the
panel, which in my case it is part of the EXP BUS 2V Tray system. So in
this application, the selector switch is activated before the "fuel pump
switch" on the panel is switched on. Therefore there should be no
opening or closing arc at the selector switch. That should make it safe
to use a 125VAC 10 amp switch as the selector switch without burning it
out or welding it closed at a ripe young age.
Thanks again,
Dred

Hi Bill,
I am looking at the same dilemma myself and have decided to just wait until my
engine mount attach
fittings are bolted on and then mark and drill the firewall. That way a couple
of mm one way or the other won't hurt. Good luck.

Perhaps I am getting this wrong, but I think the notion of where to
put the engine mount on the firewall has nothing to do with the
engine. After all, I am just a kit builder and put the holes for the
engine mount on the firewall according to the plans.
It seems to me the location of the firewall mounting bolts is
dictated by the longerons attached to the fittings on the other side
of the firewall from the engine. It is the longerons that dictate
the location of these holes.
Once the mounting position of the engine mount is fixed by the
fuselage design, it is the problem of the engine mount designer to
build a mount that fits these bolts to the engine itself.
Just my ideas on this subject . . . .
