to
"ON" position. To
turn,
rotate
console ROLL knob in desired direction. (Maximum angle of bank should not exceed 30°.)
(2)
For heading mode, set directional
gyro
with magnetic compass. Push directional gyro HDG
knob in, rotate bug to
aircraft heading. Push console heading rocker (HDG) switch
to
"ON"
position.
To select a new aircraft heading, push D.G. heading knob "IN" and rotate, in

(1)
VOR Navigation
a.
Tune and identify VOR
Station. Select
desired course by rotating
CRS
knob of H.S.I.
b. Select
OMNI mode on Radio Coupler.
c.
Select
HDG mode on autopilot console
to
engage coupler. Aircraft will
turn to
a 45°
intercept
angle
to
intercept
the
selected VOR course. Intercept angle magnitude
depends on radio needle
off course magnitude, 100% needle deflection
will result in
45° intercept with
the intercept
angle diminishing as
the
needle off set diminishes.
d. NAV mode
-
NAV mode provides reduced VOR sensitivity for
tracking weak, or noisy
VOR signals. NAV mode should be selected after the aircraft is established on course.
(2)
ILS-LOC Front Course
a.
Set inbound, front, localizer course on H.S.I.
b. Select LOC-Normal non-Radio Coupler to intercept and track inbound on
the localizer.
Select LOC-REV
to
intercept and
track outbound to the procedure
turn
area.
c.
Select
HDG Mode on autopilot
console
to
engage coupler.

ILS
-
Back Course
a.
Set
inbound, front localizer course on H.S.I.
b.
Select LOC-REV on radio coupler
to

track
inbound on
the
back
localizer
course.
Select LOC-NORM
to
intercept and
track
outbound
on the back course to the
procedure
turn
area.
c.
Select HDG mode on autopilot console
to
engage coupler.
(e)
Radio Coupling
-
VOR/ILS
with Standard directional
gyro.
(Optional)
Radio Coupler operation
in conjunction with a standard directional gyro and VOR/LOC
display differs from operation with an integrated display (H.S.I.) only in one respect. The HDG
bug is used as
the
radio course datum and therefore must be set
to
match
the
desired VOR course
as selected on the O.B.S.
(1)
For VOR Intercepts and Tracking:
Select the desired VOR course and set
the
HDG bug
to the
same heading. Select
OMNI mode on the coupler and HDG Mode on the autopilot console.
(2)
For ILS
Front Course Intercepts and Tracking:
Tune the localizer frequency
and place the
HDG bug on
the inbound, front
course
heading. Select LOC-NORM mode on
the coupler and HDG mode on
the autopilot
console.
(3) For LOC Back Course Intercepts and Tracking:
Tune
the
localizer frequency
and place the HDG
bug
on
the inbound
course
heading
to the airport. Select LOC-REV mode
with coupler and HDG mode
on
the
autopilot console.
