Turn and Pitch Controller
The turn and pitch controller (Figure 16-62)
consists of a pitch wheel and turn knob.
Pitch Wheel
Rotation of the pitch wheel results in a change
of pitch attitude proportional to the rotation of
the pitch wheel and in the direction of rotation
during autopilot operations. The pitch wheel
provides either rate limited pitch commands in
pitch mode or vertical reference commands
for vertical flight guidance modes that refer to
the air data command function. The pitch thumb
wheel provides dual tachometer outputs that
apply to both flight guidance computers.
NOSE DN–NOSE UP WHEEL
MOVING THE NOSE DN–NOSE UP PITCH WHEEL CHANGES
THE PITCH ATTITUDE PROPORTIONAL TO THE ROTATION
OF THE PITCH WHEEL AND IN THE DIRECTION OF THE
ROTATION. WHEN FLIGHT DIRECTOR VNAV AND APP
(GLIDE-SLOPE CAPTURED) MODES ARE USED, THE NOSE
DN–NOSE UP WHEEEL OPERATION IS CANCELED.

TURN KNOB
PROVIDES BANK COMMANDS TO THE AUTOPILOT (FGC 1
AND FGC 2) PROPORTIONAL TO KNOB DISPLACEMENT. WHEN
ROTATED OUT OF DETENT (CENTER POSITION), THE LATERAL
MODE SELECTED ON THE FLIGHT DIRECTOR IS CANCELED
AUTOMATICALLY. WHEN RETURNED TO THE DETENT POSITION,
A LATERAL MODE CAN BE SELECTED. THE AUTOPILOT CANNOT
BE ENGAGED IF THE TURN KNOB IS OUT OF DETENT.

Turn Knob
Rotation of the turn knob out of seated detent
with the autopilot engaged results in a roll
command. The rollangle is proportional to
and in the direction of the TURN knob rota-
tion. The TURN knob controls dual detent
switches to provide identical roll commands
to both flight guidance computers. The TURN
knob must be in detent (center position) be-
fore the autopilot can be engaged. Rotation of
the TURN knob cancels any lateral flight di-
rector mode selected.

NOTE:
THE PITCH WHEEL CAN BE USED FOR
VERTICAL REFERENCE ALTERATIONS
RELATED TO IAS/MACH, VS, AND AIR
DATA MODES WHEN THE AUTOPILOT
IS ENGEGED.
