B KLN 94
Rev. 4, Jan/2003 10599I04.CDL Page 2-79
The GPS is the selected sensor on the primary NAV indicator. The primary NAV indicator shows
the signals that the autopilot uses.
Turn the KLN 94 on to initiate its self-test sequence. While the KLN 94 performs its display test,
be ready to engage NAV mode on the autopilot, but do not engage the NAV mode yet.
When the NAV flag on the CDI/HSI moves out of view, immediately press the NAV button on the
KFC 225 computer to engage NAV coupled mode. If unsuccessful, the autopilot will only NAV
ARM and not show NAV coupled. If this happens, the KLN 94 must be turned OFF, then turned
ON again before the next attempt is made to engage the NAV coupled mode.
When the autopilot is in NAV coupled mode, then:
Turn OFF the KLN 94 cursor by pushing the CRSR button.
Push the KLN 94 PROC button.
Push the KLN 94 OBS button.
Push the KLN 94 PROC button.
Push the KLN 94 OBS button.
The KLN 94 should be outputting a signal equivalent to a 10 degree right bank. This should be
evident by the command bars indicating an approximate 10 degree right bank.
Push the KLN 94 CRSR button. The command bars should return to the wings-level state.

(where XXXX represents the last four digits of the KLN 94 Application Software 206- number and
DD MMM YYY represents the Day, Month and Year of the installation)
