commands a vertical speed
climb in which the aircraft
slows to the minimum airspeed,
the aircraft will maintain that
airspeed and will flash
MIN AS
on the display.
Likewise if the pilot commands
a vertical speed descent in
which the aircraft accelerates to
the maximum airspeed, the
autopilot will not fly the
selected vertical speed, but will
maintain the maximum airspeed
and flash
MAX AS
.
Gyro Set
When the initializing has
been done correctly, the gyros
should already be centered at
the time of take off. If
confirmation of this is desired,
with the aircraft stationary on
the runway and the autopilot
disengaged, pressing and
holding the encoder knob will
put the gyros in the fast
centering mode. The knob
should be depressed for
approximately 15 seconds
during which time the words
GYRO SET
will be displayed.
Power Loss
If there is a momentary
loss of electrical power, the
autopilot will disengage and
repower up. The autopilot gyros
may need to be manually re-
initialized using the
GYRO SET
operation. Manually fly the
aircraft in a straight line as
steadily as possible, while
holding in the knob for at least
ten seconds after the words
GYRO SET
appear in the
display. Continue to hold for
approximately ten seconds,
release the knob. The autopilot
may now be re-engaged, and
any residual gyro offset will be
slaved away automatically.
