3. At the desired point, HDG mode is used to initi-
ate the procedure turn. During the procedure
turn outbound, the deviation bar shows that the
aircraft is flying away from the localizer center-
line at a 45° angle on a selected heading of
283°.
4. Now you have reset the heading bug to 103°
and made a 180° turn to this heading. The
103° heading will intercept the front course of
058°. You must now select the approach mode
by depressing the APR button on the KFC 225.
Automatic capture of the localizer will occur.

1. The aircraft is heading 270° with heading and
altitude hold engaged. To intercept and fly the
ILS front course outbound, set the front course
on the HSI and depress the back course (REV)
button. The back course (REV) mode is
selected to go outbound on the front course.
The capture point is now being computed
based on closure rate.
2. When the computed capture point is reached,
HDG mode is cancelled and reverse localizer
mode is automatically activated and a left turn
outbound on the localizer is initiated by the
autopilot.
Note: The left-right deviations of the HSI course
needle operate just as though you were flying a
front course approach.
