*** Don't those have Terrain? I am reminded of my CFI Bob, who flew a
Baron into a mountop in May. At the time, a friend mentioned that he
had "one of those fancy new Terrain-mapping GPS's". I didn't think much
of it at the time. Now I think that Bob was using the GPS to wend his way
though the mountains, and it backfired on him. Let us be careful that
superior equipment does not tempt us into inferior judgement.

*** I bought one of these with high hopes. There is alas no AC at the
tiedown. So I got the kind with a big solar cell. Left the solar cell on
the glareshield with the control unit hanging under the airplane and
clipped onto the external power connector. Alas, it rained, and water ran
down the wires into the control unit, which died. Back to the Ole drawing
board.

I find the idea of electronic desulphators fascinating. Have purchased
and scrounged parts to build one, but haven't got around to it.

*** I just replace the ship's battery once a year. Sigh.

*** My backup/reliability strategy is about like this:

* Overhaul the gyros every 500 hours.
* Replace the vacuum pump every 500 hours
* Replace the main battery once a year
* "Do" the mags every 500 hours
* Keep my partial panel skills sharp: In fact, I don't look at the AI
much even when it works. A side effect of having spent my first 300
hours in airplanes that didn't have one. I suspect that I fly
IFR less well than I would if I had the "AI habit", but it helps
with the partial panel stuff no end.
* vetical-card compass, so it's easy to read ( even though it has ALL
the error modes of the wet compass )
* KX-99 transceiver in the flight bag. Battery pack is separated from
the transceiver so it is always fresh. Learned the hard way that if
I leave it installed, the volume knob will always somehow get jogged
on. Backup COM and NAV.
* Little Magellan "backpacker" GPS in the flight bag. No batteries in
it. ( otherwise they'd be dead when I needed them )
* Block of plastic-wrapped AA cells in the flight bag.
