Databases
The G500/G600 Txi system utilizes databases to provide some system functions.
Database status information is available to the pilot at system startup on the
MFD splash screen and during normal operations on the MFD system status page
for units with an MFD, or PFD Menu for PFD only units. Controls are provided for
enabling database sync and chart streaming and for manually initiating a
database update. EIS-only units do not support database functions. System time
(as received from an interfaced GPS navigator or the internal backup GPS) is used
to determine if a database is within its effective period. On the splash screen,
databases are displayed in amber if they are expired, not yet effective, or if the
current date/time is unknown. Databases are displayed in white if they are
within their effective date range. All database status information is depicted in
white on the System Status page.
The GDU utilizes two sets of databases
–
those which are active, and standby
databases which are databases whose valid period has not yet begun. Upon
reaching the effective date of a standby database the pilot is prompted to update
the database in use.
Internal database validation prevents incorrect data from being displayed.
Databases can be updated using an SD card, by Syncing with other compatible
units, or using database concierge through a FS510 and PED. Databases are
stored internally on the GDU.
The terrain and basemap databases are updated periodically and have no
expiration date.
The Garmin or Jeppesen navigation database contains data associated with
navigation including airports, navigation aids, airways, airspaces, and other data.
The obstacle database contains data for obstacles and wires that pose a potential
hazard to aircraft. Obstacles 200 feet and higher are included in the obstacle
database. Wires which have been identified as a hazard to fixed wing aircraft are
included in the database. Coverage of the obstacle database includes the United
States and Europe. Wire coverage is limited to the United States. This database
is updated on a 56-day cycle.
