I have had an in flight fuel starvation event that was not resolved
until after a no power landing which was successful. I know from that
experience that a fog of confusion came over me and after replaying the
event in my mind, I could not recall the point that the aux fuel pump
was turned on. I had been through the drill many times to simulate an
engine out emergency but I know for me when it actually happened, I did
not perform as well as I could/should have. An automatic switching to
the aux fuel pump could potentially take care of a problem without me
having to remember to do it in the event of the fog. Of course I would
want some indication of the switch occurring.

| Subject: | intercom noise (was radio noise) |
When my (Rotax 912) engine goes over 3800 RPM it breaks the squelch on the
radio, the radio goes in RX mode and I hear a bunch of white noise, which
for all intents and purposes makes receiving transmissions very difficult.
I have been through several iterations of this problem (see previous posts,
involving a noisy Autopilot on the 130Mhz which is our local frequency) but
yesterday I realized that if I turn the intercom off the problem disappears
(the radio doesn't go into RX mode).
So it appears that there is some kind of noise source which makes its way
into the Intercom (it's a GMA 240). What steps can I take to get rid of
this problem? I have already shielded the magneto wires.

With FlyEFII's Bus Manager/Relay system when a loss of pressure is detected
(because of a voltage drop from the pressure sensor) the main pump is
switched off and the auxiliary pump is switched on, along with their
corresponding indicator lights.
I would be interested in Robert Nuckoll's evaluation of this system with
regards to reliability of keeping the fuel pumps pumping. PDF attached.

When I say "white noise" I mean interference noise that seems related to
engine RPM.

I'm not associated with any avionics manufacturer, but I know from
experience with several Garmin audio panels that they just don't reject
noise as well as PS Eng audio panels. In several cases, changing to a PS
got rid of whines, buzzes, static, etc. that extra shielding and ground
loop witch hunts just didn't fix. What you're hearing may just not be
resolvable with a Garmin. I really like a lot of their other products, but
the audio panels aren't as good.

Why not just put in a 12v socket and purchase a plug in car charger from a retailer?

Because some are very noisy, and some don't charge ipads.
There was some interest in such a device here a few weeks/months ago.

I have a griffin charger that will charge my iPad and my phone simultaneousl
y.
Hasn't caused any noise in any certified aircraft that I have flown.

I received the following from the RV-12 owner:
> during Pre-start: LEDs ON steady(with the alarms on the D180 indicated, the LEDs
should be blinking until the 1-6 alarms are cancelled)
>From that it seems that the D-180 dimmer output is NOT set up correctly to flash
when alarm conditions exist. The RV-12 owner is out of town until Sept 3,
so troubleshooting is on hold.
Bob, you may have hit the nail on the head when you asked, "Do I presume correctly
that he has gone through the set up screen for managing the output of this
pin?"
