BACK COURSE
APPROACH - (REV)
If a back course approach is
required, it can be accomplished
as easily as a front course
approach. The course arrow
should always be set on the front
course inbound localizer course.
This will result is conventional pic-
torial deviation sensing even on
3
back course. The KI 525A display
gives you an accurate picture of
where you are at all times during
the approach and procedure turn.

1. You are outbound on the back localizer
course, having already set the course
pointer to the inbound front course at 238°.
The heading bug is preset at 193° for the
procedure turn. (Since there is usually no
glideslope signal on a back course, the
glideslope pointers are out of sight.)

3. Now you've reset the heading bug to 013°
and made a 180° turn to this heading. This
013° heading will intercept the back course.
The KI 525A clearly pictures the course you
are to intercept and the angle of intercep-
tion.

2. During the procedure turn outbound, the
deviation bar shows pictorially that the air-
craft (as represented by the symbolic air-
craft in the center of the KI 525A) is flying
away from the localizer centerline at a 45°
angle when the heading bug is under the
lubber line. Note that left-right deviations of
the course bar give "fly-to" indicators, just
as on the front course.
GS GS

4. You have smoothly intercepted the back
course. Since the course arrow is set on the
front course (238°), the KI 525A shows a
true picture of the situation - flying inbound
on the back course. You may reset the
heading bug to 058° for easy reference.
Note: For system limitations refer to your
Flight Manual Supplement.

General Emergency Procedures

Autopilot Malfunction

An autopilot, autopilot trim or manual electric trim malfunction may be recog-
nized as an uncommanded deviation in the airplane flight path or when there
is abnormal control wheel or trim wheel motion. The primary concern in react-
ing to an autopilot or trim malfunction, or to an automatic disconnect of the
autopilot, is in maintaining control of the airplane. Immediately grasp the con-
trol wheel and press and hold down the A/P DISC/TRIM INTER switch
throughout the recovery. Manipulate the controls as required to safely main-
tain operation of the airplane within all of its operating limitations.
CAUTION: Refer to the Airplane Flight Manual or the Airplane Flight Manual
Supplement for your particular aircraft for pertinent emergency procedures.
