Have you planned on static wicks? If you are really going to plan on IFR, IMHO
they are a must. I had both comms fail in the clouds prior to installing them
on my current plane. After 19 years, I have never since had an issue. I am
planning on installing them on our current RV-10 project.
I agree with Robin, I went through the failure mode analysis, and the steam gauges
are not really necessary. Use a Dynon D6 or such and free up some space.
It comes with an internal backup battery that will last you well over an hour.
Put it on the left side were you have the AH.
I don't understand your comment regarding trim issues and using the VPX-pro. I
have the VPX setup, and I have the trim running through the VPX. The only issue
I could see would be a total VPX failure, which would kill the trim servo.
The VPX has the stuck switch feature and will allow operation of the trim from
the EFIS.

Well, my current plane is well equipped with 1990s and older radio
equipment, without static wicks, is within 15 mph of the RV-10 in cruise,
and has never had static wicks in its 47 years. Has not had any sort of in
flight radio failure in the 14 years I've owned it. So I'm not so sure
about the "must". Maybe if that IFR is in high static producing
conditions. If installed, there needs to be bonding strap at the hinges of
control surfaces and control surfaces need to be balanced with the wick
installed.

Hi Bill
I am not sure about static wicks at this time. I wont be painting the aircraft
until about a year after I start flying which is hopefully this fall so I have
some time to decide.
As far as the VPX, itdoes a great job protecting you from a relay failure as its
not only solid state with the higher reliability but its using the equivalent
of two "relays" in series with both having to commend a trim change for it to
occur.
As far as switch failure, I think the timed activation feature provide by another
vendor is better. The VPX literature states that for switch failure all you
have to do is give opposite trim and the trim motor will stop. Well if the
switch is broken maybe its stuck and wont operate in the opposite direction.
So I would have to realize I have a runway trim then try opposite trim, and if
that doesnt work go for the copilot stick or try to bring up the menues in the
VPX to shut the trim off as the forces on the stick are getting larger and larger.
Doesnt sound like a good plan to me and by the time it gets turned off
I will probably be at max trim condition.I prefer a trim off switch on the panel,
no thinking necessary. I dont want to get to the max trim condition to
begin with, the fact that I can bring the trim back to neutral after the max trim
condition occurs is nice but not sufficient by itself.

The risks of lightning strike causing multiple panel failures of glass equipment
in an all-metal plane like an RV are extremely low. Your fuel tank is more likely
to explode, in which case your instruments are the least of your worries!
[Shocked]
The beauty of a properly constructed metal-skinned plane is that the electric charge
in the highly conductive aluminium until it exits back to the atmosphere
an instant later. They might flicker briefly, but having been hit by lightning
multiple times in a big aircraft, I've never seen a glass instrument fail. They
barely skip a heartbeat (more than I can say for myself!)
"Glass" redundancy is the norm for the big jets now. They generally have a backup
PFD, much like the Trutrak "Gemini", which is totally independently powered.

Mike,
I agree with your post, except that the -10 is not an "all metal" plane. The top
half - including where my head resides - is non-conducting fiberglass. I would
hope a lightning strike on the cabin top would find the path of least resistance
down the center post. But if the strike is off center it might think my
body is the way to go!

With the VPX system, when it detects a stuck switch, it disables the mechanical

Kind of a wash. You pay shipping to send one back and get new correct
wheel(and highly recommend axle) or you get credit for wheel at less than
1:1 if you delete from order. I think the latter is less hassle.

Hey Bill,
Maybe I am missing something but I dont think the VPX can detect a stuck switch.
I don't believe it has a way to detect if a switch is on because you are commanding
it or its on because its stuck, it also has no timer to detect how long
a switch has been on. It fact I don't think there is a way to detect that
at all. It has no circuitry inside the switch, so all it knows is the switch
is on or off. If you know otherwise please point me to the pertinent section
in the manual.
Thanks
Niko

Mike,
Extremely low risk is a relative term.
I don't know how you have reached that conclusion but I don't think its true.
On non-certified equipment its anyones guess as to how tolerant these computers
are to lightning As I have stated earlier, I believe your statement is true
for large cockpits with certified equipment, i.e. airliners, but not true for
the small craft we are flying. There are document cases in RVs where lightning
took out the EFIS, there are also document cases of damage to instruments due
to lightning in many aircraft.

If you know anything about the electrical standard DO-160, most of the
non-TSO EFIS meet this DO-160 standard which is the same as TSO
electronics meet. It is a standard as to withstanding voltage spikes and
other system disruptions. I really don't see that the size of the
cockpit has anything to do with it, since the length of electrical path
has little to do with transmission of a lightning discharge.

I reached that conclusion because although there may have been RVs hit by lightning
I'm not aware of any which have been "brought down" by it, or where pilots
have been fried by it. This fact leads me to conclude that the chances of a
lightning strike causing your premature demise while you're out flying are very
low. [Wink]

I disagree. If the uncertified equipment from certain manufacturers is not at least
crafted with fault-tolerant design principles and DO160 in mind, I'd be a
little disappointed and openly wonder why they're inflicting it on the OBAM community
(and why people are buying it).
> There are document cases in RVs where lightning took out the EFIS, there are

I guess my whole point is: how far do you want to take this? I mean, fighter pilots
don't have metal roofs over their heads either. I've known of accidents where
the pilot has been killed by a birdstrike, a "tree" strike, a heart attack,
GLOC, even by the ricochet of their own explosive ordnance, but never a lightning
strike, even though aircraft get hit now and again. From the instrument
perspective, backup basic flight instruments of some form (electronic or otherwise)
are essential for sure, with an independent power supply of course. But
how far do you want to take it?[/quote]
