mation from the current database to define the waypoints.
If the database is changed or updated, the G1000 system
automatically updates the information, provided the pro-
cedure has not been modified. Should an approach, de-
parture, 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 in-
stallation. 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 Aeronau-
tical 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 ac-
tive-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 auto-
matically 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 is 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 pub-
lished 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 pat-
terns. The OBS softkey is used to suspend waypoint se-
quencing and select the desired course along the waypoint
side of the hold. For many approach operations, setting
and resetting of waypoint sequencing is automatic. Hold-
ing 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 soft-
key. An example of this operation is an approach which
begins with a holding pattern at the initial approach fix
(IAF).
The most common application for using the OBS soft-
key is the missed approach. The G1000 suspends au-
tomatic waypoint sequencing (indicated by a “SUSP” an-
nunciation placed on the HSI) when the missed approach
point (MAP) is crossed. This prevents the G1000 from
automatically sequencing to the missed approach holding
point (MAHP). During this time, the
OBS softkey desig-
nation changes to
SUSP
. Pressing the
SUSP
softkey reac-
tivates automatic waypoint sequencing. The OBS softkey
then resumes its normal functionality.
WARNING: The G1000 does not provide guid-
ance to the missed approach hold point (MAHP).
Always follow published missed approach proce-
dures when flying a missed approach.
