IFR Avionics Preflight Checklists

Does anyone use a separate Avionics Checklist prior to departing IFR?
I am in the process of developing my own and would appreciate seeing
what others are doing. Please cut and paste a posting to the group or
email me directly.
Thanks.

I don't have a copy of our checklist here at home, but I'll try to do it
from memory.

1. GPS - Go through whatever function checks you have for your GPS. They
should be in the manual that came with the unit.

2. VORs
a. Tune both nav radios (if you have more than one) to a VOR.
b. Center both course needles with a TO indication and compare them.
c. Change both CDIs (if you have two) more than 10 degrees and check
for full-scale deflection of the needles. Then move the CDIs past 90
degrees and check for TO/FROM change. Center both needles with a FROM
indication and compare them. If you only have one CDI, insure that the
centered indications are more or less correct, depending on the distance
from the station.
d. Set the CDIs to the desired course.
e. Identify the station with the audio, and if you have a
VALID/INVALID light, tune the VOR off the station and check for an INVALID
light with no signal.

3. ADF - check the bearing pointer, see that it points in the right
direction for the station tuned, and moves with a new station.

4. DME - Check that it's operational, and giving correct information, if
you can receive a signal.

5. Marker Beacon - test.

6. Radar Altimeter - test.
