l.
CONTROL UNIT - Provides the primary switches and controls for operating the
autopilot.
2. PITCH CONTROL - Controls pitch attitude of airplane. When rotated toward UP,
a irplane will pitch up. When rotated toward DWN, airplane will pitch down. Pitch
a ttitude depends on displacement of control from level flight position.
3.
PULL-TURN CONTROL KNOB - When pulled out and turned, aircraft will bank
right (R) or left (L). When in detent and pushed in intercepts and maintains
selected heading (HDG). When pulled out and in detent, acts as wing leveler.
4. LATERAL TRIM CONTROL (TRIM) - When PULL-TURN knob is pulled out and
centered , control is used to trim aircraft for wings level attitude.
5.
AUTOPILOT ON-OFF SWITCH (AP/ ON) - Controls primary power to turn bn or
off the Navomatic 400B. When the AP/ON switch is turned off, the autopilot
disengage horn will produce a short tone lasting from 1 to 2 seconds with
decreasing amplitude and autopilot disconnect light will illuminate.
6.
NAVIGATION ENGAGE SWITCH (NAV) - When PULL-TURN knob is pushed
in, selects automatic VOR radial or localizer intercept and tracking operation.

8. ACCESSORY
UNIT - Provides the pilot w-ith an automatic autopilot disconnect
warning light, an autopilot disconnect system self-test button for use prior to
flight, a reverse sense (back-course) selector switch and a navigation receiver
selector switch.
9. BACK COURSE REVERSE SENSE (REV SNS) LOC 1 OR LOC 2 SELECTOR
SWITCH - Used with LOC operation only. With AP switch OFF or ON, and when
navigation receiver selected by AP switch (on autopilot accessory unit) is set to a
localizer frequency, it reverses normal localizer needle indication on a course
deviation indicator (CDI) and causes localizer reversed (BC) light to illuminate.
With AP switch ON (on autopilot flight controller), reverses localizer signal to
autopilot.
CAUTION
When an optional horizontal situation indicator (HSI) is insta lled,
the omni deviation bar does not reverse. However, with AP SWITCH
ON ( on autopilot flight controller), selection of either LOC 1 or LOC
2 will always cause the localizer signal to the autopilot to reverse
for back-course operation.
10. AUTOPILOT (AP) NAV 1 OR NAV 2 SELECTOR SWITCH - Selects a ppropriate
signals from the desired navigation receiver.
11. AUTOPILOT DISCONNECT WARNING INDICATOR LIGHT (DISC WARN)
Whenever the autopilot is disengaged by any means, other than the control wheel
