Databases
The GI 275 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 Menu → System →
Databases (or DB) menu. Controls are provided for manually initiating a
database update. EIS units only use a Nav database. System time (as received
from an interfaced GPS navigator or the internal VFR GPS) is used to determine
if a database is within its effective period. Databases are displayed in yellow 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.
Databases can be updated using the USB port, by syncing with other compatible
units, or using database concierge through a PED. Databases are stored
internally on the GI 275s.
The terrain and basemap databases are updated periodically and do not expire.
The Garmin or Jeppesen navigation database contains data associated with
navigation including airports, navigation aids, airways, airspaces, and other data.
This database is updated on a 28-day cycle.
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.
CAUTION
Not all obstacles or wires are included in the databases.
The Garmin SafeTaxi™ database contains airport diagrams for selected airports.
This database is updated on a 56-day cycle.
The magnetic variation model contains data about variations in the earth’s
magnetic field based on location. This database is included with the navigation
database and is updated on a five-year cycle.
Crew Profiles
The crew profile function is provided for all units to allow the retention of pilot-
selectable configurations and settings. If the aircraft is operated by multiple
pilots, each pilot can recall their individual settings for use. These profiles
include settings from all displays in the system.
If an MFD is installed, the splash screen provides the option for the pilot to
select a crew profile upon power up. Otherwise the crew profile can be set in the
System → Crew Profile Menu. If no selection is made, the GI 275 will default to
