backup for vacuum pump/attitude indicator failure

Is this really true? I cannot mount an unapproved CD
player someplace
so that it won't flop around in flight?
yes

Actually, I spoke to our FSDO not too lona ago with this very question,
and the answer came back that it is legal to do so. The =installation=
needs to be approved (the installer can self-approve) but the device
being installed need not be an approved device, so long as it is not
powered directly by the aircraft system (cigarette lighter power is ok).

They are concerned that the installation not interfere with flight
controls and such. They are concerned that a non-approved device not
take the place of an approved instrument, but according to my FSDO, once
I explaned all we wanted to do (install an electric backup AI), they
were ok with it.

YMMV

yes

Not true in the slightest. You want to velcro your CD player to the top
of the glareshield or maybe to the floor have at it. I have my
satellite radio attached to the far left side of the panel with that two
sided 3M sticky tape they give you with the radio. That stuff is better
than screws because when I want to remove it you'll never know it was
there and if you've worked with that tape before you know how solid it
is. I run the power, antenna and audio out cables under the glareshield
and then out to where they need to go.

See the current "Tech Topics" article in CPA Magazine. It's not quite as
clear-cut an answer as this.
