(c)
Roll Section:
(1)
To engage, center roll knob, push A/P “ON-OFF” switch 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
desired direction of turn, to the desired heading.
(d)
Radio Coupling VOR-ILS with H.S.I. (Horizontal Situation Indicator) Type Instrument Display -
(Optional)
(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 offset 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 on radio coupler to intercept and track inbound on localizer.
Select LOC-REV to intercept and track outbound to the procedure turn area.
c.
Select HDG mode on autopilot console to engage coupler.
(3)
ILS - Back Course
a.
Set inbound, front localizer course on H.S.I.
b.
Select LOC-REV on radio coupler to intercept and 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 OBS.
(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.
