TruTrak Sorcerer – Outdated - Manual (Page 5)

Controls
Switches labeled
[NAV] [REV] [SEL] [VNAV]
when depressed enter the
respective lateral and vertical
mode setup screens. When the
desired setup screen is
displayed, the numerical data to
be entered will be underlined.
The data is then set by rotating
the encoder knob and entered
by depressing and then quickly
releasing the knob. This will be
referred to hereafter as “enter”.
The
[TRK] [ALT] [AP]
[GPSS] [GPSV] buttons do
not have setup screens; they
enter directly into the respective
modes.
Another means of entering
numerical data is the sequential
pressing of the vertical speed
rocker. Each time the rocker is
pressed, the vertical speed will
be changed in increments of
100 feet per minute. If the
vertical speed rocker is pushed
and held, the vertical speed will
slowly scroll up or down in the
desired direction. Still another
means of altering the display
presentation is engaging or
disengaging the autopilot. This
is accomplished by using the
[AP] switch on the
programmer. If GPS Steering
or Vertical GPS Steering is
available, the [GPSS] [GPSV]
switches will also engage the
autopilot. The control stick
switch located on the control
wheel or stick is yet another
means of engaging the
autopilot. The control stick
switch serves a dual purpose.
Momentary closure will
disengage the autopilot. If the
switch is held closed more than
two seconds, the autopilot will
engage upon release. This
means that in addition to
disengaging the autopilot, this
switch also provides the
function referred to as Control
Wheel Steering in that the
autopilot synchronizes to both
direction and vertical speed
upon being engaged.
Lateral Modes
Upon being engaged, the
autopilot will be in the basic
lateral mode, and it will be
synchronized to the track being
flown at the time. (See figure
on page 3.) Note: The number
following
SEL (Selected
direction) is underlined,
meaning that rotation of the
encoder will select a new
ground track. Rotation of the
knob when it is not depressed
will cause 5
° steps of
SEL and
when it is depressed the steps
will be 1
°.
If the autopilot is in another
lateral mode, pushing the
[TRK] button will enter the
basic track mode.
When an external heading
source (DG or HSI) is present,
pressing [TRK] will toggle
between the
EXT DG and the
track mode. When in the EXT
DG mode the heading “bug”
within the external DG or HSI
