Default Dual Vac (Pressure) failure in IMC, Night, yikes.

Last week, 3 of us where trying to get to Kissimmee from TN but Florida was
closed off due to a line of severe thundershowers across the state. Waited
in Waycross (great FBO, btw) then set off at 9pm into the night with XM
weather and a storm scope. Most of the stuff had dissipated but we did have
to do an end around some the remnants. During one of the trips thru the
clouds, the Gyro warning light came on and I looked over to see Zero
pressure. No prob. just hit the backup Standby Gyro and keep going. 5
minutes later, the light came back one and we had the same reading. What
are the chances? Went the rest of the way (better weather ahead rather than
behind) partial panel with both AI's covered up.



The last time I had an instrument failure, I lost my primary AI on takeoff from
Cincinnati in the middle of the night. My instrument scan then went from my
side of the panel to glances at the AI on the copilot's panel. This was in a
C-402B... I was glad to have it (the second panel)but it was really no big deal.
I might have had a different attitude (pardon the pun) about it if the air had
been rough.
