3.12 NAV Indicator Interface
3.12.1 Applicable Part Numbers
All part numbers and software revisions perform all NAV indicator functions. The comosite indicator
interface is only available in KSN 7x0 models.
interface is only available in KSN 7x0 models.
3.12.2 Function
The NAV indicator displays the lateral deviation from selected course, TO/FROM indications, and NAV
flag (both meter level and superflag). In addition, the KSN 7xx includes outputs for vertical deviation,
meter flag, and superflag.
flag (both meter level and superflag). In addition, the KSN 7xx includes outputs for vertical deviation,
meter flag, and superflag.
The KSN 7xx has the ability to read selected course from the NAV indicator. The selected course is used
by the KSN 7xx in both the leg and OBS modes. In OBS mode, the NAV indicator selected course is
input as the GPS selected course, eliminating the need for the pilot to select the course on both the
indicator and the KSN 7xx. In Leg mode, the KSN 7xx notifies the pilot when there is a discrepancy of
5 degrees or more between the KSN 7xx magnetic desired track and the NAV indicator selected course.

An input called GPS DISPLAYED tells the KSN 7xx whether its navigation information is presently being
displayed on the NAV indicator and consequently whether the NAV indicator selected course must be
used by the KSN 7xx.
displayed on the NAV indicator and consequently whether the NAV indicator selected course must be
used by the KSN 7xx.
The KSN 7xx provides selected course drive capability for EFIS. Slewable NAV indicators (XYZ or
SIN/COS drive) may be driven by the KSN 7xx. When interfaced with nonslewable NAV indicators, the
pilot is directed with messages to manually move the course selector to match the selected course
displayed on the KSN 7xx.

3.12.3 Requirements and Limitations
IFR certified installations of the KSN 7xx are required to have a NAV indicator installed, and it must be
located in the pilot’s primary scan area. RS-232 receivers may not be used as the primary flight display
for the KSN 7xx.
located in the pilot’s primary scan area. RS-232 receivers may not be used as the primary flight display
for the KSN 7xx.
Selected course may be input as OBS SIN/COS, RS 422, or ARINC 429. Only one of the three possible
interfaces can be connected in the aircraft.

GPS DISPLAYED must be connected if the selected course is input as OBS SIN/COS or RS 422.
GPS DISPLAYED is not required if selected course is input as ARINC 429 into the EFIS RECEIVER. In
addition, the Maintenance page must be configured for OBS RESOLVER: Y, for the OBS SIN/COS
inputs to be used.

KPI 552, KPI 553, and KPI 553A units which interface with Bendix/King KNR-665A or KNR-615 units
do not have course selection knobs. Some certification agencies require entry of OBS selected course
on the CDI/HSI.

NOTE: In the cases of the following ports, unused pins must be configured as “None” or “N” on the
Maintenance pages for proper operation. Open pins configured as being used will flag data and
may generate failure messages:
