The most common application for using the OBS Softkey is the missed approach. The G1000H suspends
automatic waypoint sequencing (indicated by a ‘SUSP’ annunciation placed on the HSI) when the missed
approach point (MAP) is crossed. This prevents the G1000H 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 DOes the g1000h nOt aUtOmatically seqUence tO the neXt wayPOint?
The G1000H only sequences flight plan waypoints when automaticsequencingisenabled(i.e.,no“OBS”or
‘SUSP’ annunciation). 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 G1000H 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?
The G1000H smooths adjacent leg transitions based on a normal 15° bank angle (with the ability to roll up
to 30°) and provides three pilot cues for turn anticipation:
•Awaypointalert(‘NextDTK###°in#seconds’or‘NextHDG###°in#seconds’)appearsonthePFD10
seconds before the turn point and flashes as it counts down to zero.

is displayed when the pilot is to begin the turn and the HSI (GPS mode) automatically sequences to the next
DTK or HDG value.
