Points to Remember for Localizer or VOR-
based Approaches
• The default factory setting allows the CDI output to
automatically switch from the GPS receiver to the
LOC receiver. This may be changed to manual in
some installations. If the “ILS CDI Selection” setting
is changed to “Manual”,
you must determine when
to select “GPS” or “VLOC” guidance during the
approach. Remember, “VLOC” is required for the
final course segment from Final Approach Fix (FAF)
to MAP.
If the ILS CDI Capture setting is changed to
“Manual”, you must select VLOC guidance
manually by pressing the CDI key.
NOTE:
Installations with certain autopilots, such as the
KAP 140 and KFC225, do not allow automatic ILS CDI
switching.
• If the CDI output has not automatically switched
from GPS to ILS upon reaching the FAF, you must
manually switch to the VLOC receiver by pressing
the
CDI key. Verify that “VLOC” is displayed directly
above to the CDI key.
• Automatic switching of CDI output is available
for ILS, localizer, SDF and LDA approaches. Auto-
matic CDI switching is
not available for backcourse
approaches or VOR approaches.
• When flying an approach with the autopilot-coupled,
you must monitor system functions at all times and
verify that the autopilot and external CDI (or HSI)
switch to the VLOC receiver with sufficient time to
capture and track the approach course. Switching
to “VLOC” late in the approach may not provide the
autopilot enough time to respond and intercept the
approach course prior to the FAF (depending upon
the performance characteristics of your autopilot and
aircraft). In such instances, you should manually fly
the approach or refer to the documentation provided
with your autopilot.
• When an ILS or VOR approach is first selected or
executed, the frequency is automatically checked.
If the frequency is correct, you will not receive a
message regarding the frequency. If the frequency
is incorrect, you will receive a message and you
must place the ILS or VLOC frequency in the active
frequency field.
When an ILS approach is first selected, the
ILS frequency is automatically placed in
the standby VLOC frequency field. Press the
VLOC flip-flop key to use this frequency.
• When flying a localizer-based approach
(other than backcourse) with automatic CDI
switching enabled:
1. “GPS” guidance may be used while flying
outbound and on the initial portion of the
procedure turn.
2. “VLOC” guidance is used on the remainder of
the approach from the time you turn inbound
on the procedure turn.
