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).
The most common application for using the OBS Softkey is the missed approach. The G1000 suspends
automatic waypoint sequencing (indicated by a ‘SUSP’ annunciation 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 designation changes to SUSP . Selecting
the SUSP Softkey reactivates automatic waypoint sequencing. The OBS Softkey then resumes its normal
functionality.
Why might the g1000 not aUtomatically seqUence to the neXt Waypoint?
The G1000 only sequences flight plan waypoints when automatic sequencing is enabled (i.e., no ‘OBS’ or
‘SUSP’ annunciation on the HSI). For automatic sequencing to occur, the aircraft must also cross the bisector of
the turn being navigated. The bisector is a line passing through the waypoint common to two flight plan legs
at an equal angle from each leg.
hoW can a Waypoint Be skippeD in an approach, a DepartUre, or an arrival?
The G1000 allows the pilot to manually select any approach, departure, or arrival leg as the active leg of
the flight plan. This procedure is performed on the MFD from the Active Flight Plan Page by highlighting the
desired waypoint and selecting the ACT LEG Softkey then the ENT Key to approve the selection. The GPS
then provides navigation along the selected flight plan leg.
When Does tUrn anticipation Begin?

30°)andprovidesthreepilotcuesforturnanticipation:
