activated. When storing flight plans with an approach, a departure, or an arrival, the G1000 uses the waypoint
information from the current database to define the waypoints. If the database is changed or updated, the
G1000 System automatically updates the information, provided the procedure has not been modified. Should
an approach, departure, or arrival procedure no longer be available, the flight plan becomes locked until the
procedure is deleted from the flight plan.
CAN “SLANT GOLF” (“/G”) BE FILED USING THE G1000?
“/G” may be filed for a flight plan. The G1000 System meets the requirements of TSO-C129 Class A1 or A2
installation. Non-precision GPS approaches are not to be flown with an expired database. See the approved
Aircraft Flight Manual Supplement (AFMS) as well as the Aeronautical Information Manual (AIM) for more
information.
WHAT DOES THE OBS SOFTKEY DO?
The OBS Softkey is used to select manual sequencing of waypoints. Activating OBS mode sets the current
active-to waypoint as the primary navigation reference and prevents the system from sequencing to the next
waypoint in a flight plan. When OBS mode is cancelled, automatic waypoint sequencing is continued, and
the G1000 automatically activates the next waypoint in the flight plan once the aircraft has crossed the present
active waypoint.
Normal (OBS not activated)
• Automatic sequencing of waypoints
• Manual course change on HSI not possible
• Always navigates ‘TO’ the active waypoint
• Must be in this mode for final approach
course
OBS
• Manual sequencing - ‘holds’ on selected
waypoint
• Manually select course to waypoint from
HSI
• Indicates ‘TO’ or ‘FROM’ waypoint
• Cannot be set for final approach course or
published holding patterns
When OBS mode is active, the G1000 allows the pilot to set a desired course to/from a waypoint using the
CRS/BARO Knob and HSI (much like a VOR).
One application for the
OBS Softkey is holding patterns. The OBS Softkey is used to suspend waypoint
sequencing and select the desired course along the waypoint side of the hold. For many approach operations,
setting and resetting of waypoint sequencing is automatic. Holding patterns that are part of an approach
automatically disable waypoint sequencing, then re-enable waypoint sequencing after one time around the
holding pattern. To fly the holding pattern a second time, press the
OBS Softkey. An example of this operation
is an approach which begins with a holding pattern at the initial approach fix (IAF).
WARNING : The G1000 does not provide guidance to the missed approach hold point (MAHP). Always
follow published missed approach procedures when flying a missed approach.
