erection. On one mildly bumpy
flight (fortunately in severe clear
conditions), the gyro suddenly
rolled upside down. To get the
airplane fixed as quickly as
possible without breaking the
bank, my mechanic recommended
swapping the gyro for a
remanufactured one. When this
was done, I took the airplane for
a test flight and all was fine ...
until I engaged the autopilot. The
airplane promptly began a roll to

the left, which continued until I
switched the autopilot off.
A trip to the gyro shop
ensued, and it turned out that
the remanufactured gyro had
a defective roll potentiometer.
Once it was fixed, everything
worked fine.
Today, I'm a partner (with
four other pilots) in another
piston single, which has a typical
analog panel with vacuum-driven
attitude indicator and directional
gyro. We've experienced one
vacuum pump failure in the past
couple of years, and precession in

the directional gyro has required
it to be sent for overhaul in the
same period. The upshot is we're
spending several hundred dollars
per year, on average, for vacuum
system and gyro maintenance.
An alternative that interests
me - and I suspect many other
owner/operators - would
be digital gyros. For piston
applications, the Evolution from
Aspen Avionics seems to make
a great deal of sense. More than
a digital replacement for basic
gyros, the Evolution provides
"glass panel" primary flight
