APPENDIX A: DATA CARD USE
The Jeppesen NavData Card, and the Terrain Data
Card (if applicable) supplied with the GNC 420 can be
installed or removed when the GNC 420 is on or off. If the
NavData Card is not present when the unit is turned on, a
‘No Jeppesen Aviation Database - Limited to user defined
waypoints’ message appears on the Database Confirmation
Page. If the NavData Card is removed during operation,
a ‘Data card removed - Unit will restart in 30 seconds’
warning is displayed. A counter begins to count down
and, if the card is not replaced within 30 seconds, the
GNC 420 automatically re-initializes. Pressing the ENT
Key will manually re-initialize the unit.
