NOTE
The Altitude Hold may be overpowered
manually, however, upon release of the
controls, the airplane will again fly to the set
altitude, unless Altitude Hold is disengaged
before changing altitude.
3. Omni Lock
a. To Engage Omni Lock
After takeoff and at a safe altitude, engage the
Basic Autopilot as above.
Tune in Omni Station and set Omni Bearing
Selector to the desired course.
Set the Directional Gyro Course Card to match the
Omni Bearing Selector and engage the Heading
Lock.
Engage the Omni Lock by Pulling out "Omni-Pull"
knob.
b. Operation of Omni Lock
4 of 5
If the Omni needle indicates 5° or more from the
selected bearing, the airplane will turn until the
Directional Gyro heading is within 30° to 45° of
the selected bearing. This heading will be main-
tained until the needle indicates approximately 5°.
At this point the intercept angle will gradually
decrease until the needle is centered and the
airplane heading is the same as the selected Omni
Bearing.
If the intercept angle should exceed 45°, this can
be reduced and performance improved by use of
the T-3 Roll Trim Lever.
