Looks like they are coming out with a miniature transponder also.

Robin,
No I don't have the safety trim. I will check that out.
Thanks, Jim C

Robin, I had managed to miss the Safety Trim notes. That will be ordered
soon!
Tim, Great write up.

According to Mid-Continent, turn coordinators run between .28 and .35
amp (brushless vs. ...brushed? brushful?).
I use a TCW power supply to backup my GPS/Comm, Autopilot, and trim.
With any sort of power burble in IMC, I intend to immediately declare
an emergency and get to VMC before I loose Comm and AP. That doesn't
cover the "sudden and complete all-electronics failure", so hopefully
the TC and mechanical instruments would help out there.
Since transmitting is probably my biggest backup power draw, and trim
depends on conditions, so it's pretty hard to say how long the power
would last.

because he's relieved of separation responsibility; you'll be happy because
you're still in the system, so if the weather goes below VFR just call them

If there's any question of how long the backup battery will last, I'd skip the
radio call. It might cost you 15 minutes of TC time. Turn off all the radios;
turn on the nav and check position as needed.
I've practiced flying a VOR approach with no radios except a handheld nav/com.
The com makes you feel warm and fuzzy but is useless. The VOR is what you want.
A handheld aviation GPS is even better.
With all the talk about lightning's effect on avionics, I'm more worried about
its effect on me. Inside a metal cage I'm pretty safe. But with the upper half
of my body surrounded by non-conducting fiberglass, I wonder if the lightning's
path of least resistance would't be thru my salt water filled body!
