SWITCHING
It is possible to obtain an optional NAV
1/NAV 2 switching system for the KFC 150,
KAP
150
or
KAP
100
to allow the autopilot
to fly sensor information from either the
Number
1
VOR/ILS/RNAV navigation radio
or the Number
2
VOR/ILS/RNAV navigation
radio.
With the switch installed on the cock-
pit panel,
the
pilot merely flips the switch
if
he wants to have the autopilot fly informa-
tion from the Number 2 radio. This may be
particularly helpful if either the Number
1
or
Number
2
radio should fail.
When installed with a
100
series flight
control using the KCS 55A compass sys-
tem, a special status KI 525A PNI and
a
special status CDI are required. When
using the number
2
system always set the
OBS
to the desiied course. This includes
setting the front course heading for either
ILS Front or Back Course approaches.
When installed with a
100
series flight
control using the KG
107.
no special status
CDl's are necessary.
