| Quote: | Here are a few questions from my buddy who is building an RV-10 and will be using Z13/8 for his all electric panel. He is trying to use zero or as few circuit breakers on the panel as possible. He will be using fuse blocks for the main and endurance buses, so most of the usual CBs will not be needed.
|
Questions:
| Quote: | 1. "ALT FLD" wire protection z13/8: can that be a fuse or does it need to be a circuit breaker on the panel?
2. Is it feasible to think someone could react fast enough on run away trim scenario to pull the circuit breaker before it ran its full course? If not - use fuse instead of CB?
3. In z13/8, Can both shunts be hooked up to one ammeter? Would the shunt attached to the SD8 alternator indicate a load even if the aux alt switch was off? Suggestions for best way to proceed with only one ammeter?
4.If your goal was to minimize as many warning lights, switches, and CBs on the panel, what would your short list be of these items to remain? Using Dynon Skyview that will be booted up prior to start-up that will have plenty of warnings to display.
|
Thanks for the input.

If he is using crowbar ov protection, a CB is
called for . . .

Put it on the SD-8 only. That's the one
most useful for shedding loads in flight.
You're never going to overload the main
alternator.

"Plenty" ought to be enough. I've been flying in TC
aircraft for over 60 years that have zero 'warnings'.
They have gages that give you the big picture and
for nearly a century, it has been quite sufficient
to let the pilot do the pilot-thing and be aware
of the big picture.
Engines and other systems have only become more
reliable over the years while digital instrumentation
has offered us ways to raise flags, flash lights,
sound alarms and otherwise lull us to sleep in
a cockpit that makes less demands.
If you've got an electro-whizzy with warning
features not included on a 1980 A-36 Bonanza,
I suspect that will be "plenty".

Bob,
He is using the crowbar. Is there any reason that the CB should be on the panel or can it be placed out of sight?
Thanks for the help!

I am trying to do the same thing in my RV10 with a Z14. FWIW, below is
|
what I did...
| Quote: | > Questions:

I have 2 for my 2 voltage regulators - req'd per Bob.
|
| Quote: | > 2. Is it feasible to think someone could react fast enough on run away trim scenario to pull the circuit breaker before it ran its full course? If not - use fuse instead of CB?
I opted for the Safety Trim product which does 2 things; 1) limits trim
|
activation to 3 seconds per switch actuation, 2) it includes a 3
position locking switch that offers Trim on, Trim off, and Trim reverse

I have 4 CBs; 2 for volt regulators, 1 for the AP (as an emergency off),
|
and 1 for the flaps (I was imagining a scenario where flap actuation at
high speeds (why?) might blow a fuse and how I'd like to be able to
reset it (flaps not absolutely required). Next to the CBs I have the
Safety Trim switch and a switch for ADI battery backup.
Mounted the fuse block on right hand side panel and had Flightline
interiors put a cutout in the panel. A transparent panel will be
velcro'd over the panel so it can be easily accessed.
Good luck to your friend,
Bill "ready to fly" Watson

Depends on whether or not he wants the popped CB
to be the annunciating feature for an ov shutdown.
Suggest you review the philosophy and functionality
of the crowbar ov protection system. The nature of
the questions suggests that this system is not
well understood.

Bill,
Thanks for the reply. I'll pass it on my buddy.
