2.4.4.6 Moving Map Interface
If the KLN 94 is interfaced to a moving map display, verify operation by moving the aircraft out to
an open location to acquire a satellite position. Enter an active flightplan or active waypoint to
develop a presentation on the map.
Some moving maps require 2 kts of ground speed to display, as the sense track angle is used
instead of the heading. The KLN 94 does not output track angles when the groundspeed is below
2 kts.
2.4.4.7 External Annunciators
Recycle the power on the KLN 94 which will cause the Self Test Page to be displayed. Verify that
all external annunciators are energized. Cycle the KLN 94 display past all initialization pages.
Verify all external annunciators are extinguished. If the message light comes on, view the
Message Page to verify that there is a message. If any other annunciator remains lighted, review
the status of the KLN94 to determine if the lighted annunciator is justified.
NOTE
Annunciators should be checked one at a time in order to verify that the correct
one lights.
