WARNINGS, CAUTIONS, AND NOTES
NOTE : When operating the G1000 in DG Free Mode (GRS 7800 installations only), the heading information
used by some system components (e.g. GTS 8000, AFCS, and GWX) will be different from the heading
displayed on the GDU by an amount equal to the difference between the current Magnetic Field Variation
Database (MV DB) value, and the MV DB value when DG Free Mode was activated. Due to the convergence
of isogonic lines, this condition is most noticeable at or near the North and South poles.
NOTE : System navigation utilities may not reliably calculate range and bearing information when the
aircraft is operating north of 80° North latitude or south of 80° South latitude. This may result in the system
displaying small gaps in racetrack holding pattern depictions (GRS 7800 installations only).
NOTE : The Terrain Awareness and Warning System (TAWS) may not operate reliably north of 89º North
latitude and south of 89º South latitude. This is due to limitations present within the Terrain database and
the system’s ability to process the data representing the affected areas (GRS 7800 installations only).
NOTE : The FAA has asked Garmin to remind pilots who fly with Garmin database-dependent avionics of the
following:
• It is the pilot’s responsibility to remain familiar with all FAA regulatory and advisory guidance and information
related to the use of databases in the National Airspace System.
• Garmin equipment will only recognize and use databases that are obtained from Garmin or Jeppesen. Databases
obtained from Garmin or Jeppesen are assured compliance with all data quality requirements (DQRs) by virtue
of a Type 2 Letter of Authorization (LOA) from the FAA. A copy of the Type 2 LOA is available for each database
and can be viewed at http://fly.garmin.com by selecting ‘Type 2 LOA Status.’
• Use of a current Garmin or Jeppesen database in your Garmin equipment is required for compliance with
established FAA regulatory guidance, but does not constitute authorization to fly any and all terminal procedures
that may be presented by the system. It is the pilot’s responsibility to operate in accordance with established
AFM(S) and regulatory guidance or limitations as applicable to the pilot, the aircraft, and installed equipment.
NOTE : The pilot/operator must review and be familiar with Garmin’s database exclusion list as discussed
in SAIB CE-14-04 to determine what data may be incomplete. The database exclusion list can be viewed at
www.flygarmin.com by selecting ‘Database Exclusions List.’
NOTE : The pilot/operator must have access to Garmin and Jeppesen database alerts and consider their
impact on the intended aircraft operation. The database alerts can be viewed at www.flygarmin.com by
selecting ‘Aviation Database Alerts.’
NOTE : If the pilot/operator wants or needs to adjust the database, contact Garmin Product Support to
coordinate the revised DQRs.
NOTE: Garmin requests the flight crew report any observed discrepancies related to database information.
These discrepancies could come in the form of an incorrect procedure; incorrectly identified terrain, obstacles
and fixes; or any other displayed item used for navigation or communication in the air or on the ground. Go
to FlyGarmin.com and select ‘Report An Aviation Data Error Report.’
