W CDI
HEN DOES THE
When 30 nm from the destination, the G1000 begins a smooth CDI scale transition from 5.0 nm (en route
mode) to 1.0 nm (terminal mode). When 2 nm from the FAF during an active approach, the CDI scale
transitions to 0.3 nm (approach mode). When executing a missed approach, the CDI can be returned to the
1.0 nm scale by selecting the SUSP Softkey. The CDI is also set to 1.0 nm (terminal mode) within 30 nm of
the departure airport.
W HSI
HY DOES THE NOT RESPOND LIKE A
Unlike a VOR, the CDI scale used on GPS equipment is based on the crosstrack distance to the desired
course, not on the angular relationship to the destination. Therefore, the CDI deflection on the GPS is constant
regardless of the distance to the destination and does not become less sensitive when further away from the
destination.
W
HAT IS THE CORRECT MISSED APPROACH PROCEDURE
To comply with TSO specifications, the G1000 does not automatically sequence past the MAP. The first
waypoint in the missed approach procedure becomes the active waypoint when the SUSP Softkey is selected
after crossing the MAP. All published missed approach procedures must be followed, as indicated on the
approach plate.
To execute the missed approach procedure prior to the MAP (not recommended), select the Active Flight Plan
Page and use the ACT LEG Softkey to activate the missed approach portion of the procedure.

FTER A MISSED APPROACH
?
ACTIVATED
Do not attempt to reactivate the current approach prior to crossing the missed approach point
NOTE:
(MAP). If an attempt to do so is made, an alert message "Are you sure you want to discontinue the current
approach?" appears. The G1000 directs the pilot back to the transition waypoint and does not take into
consideration any missed approach procedures, if the current approach is reactivated.
After flying the missed approach procedure, the pilot may reactivate the same approach for another attempt by
pressing the PROC Key. Once the clearance is given for another attempt, activate the approach by highlighting
'ACTIVATE APPROACH' using the large FMS Knob and pressing the ENT Key. The G1000 provides navigation
along the desired course to the waypoint and rejoins the approach in sequence from that point.
To activate a new approach for the same airport, select the new procedure by pressing the PROC Key. Choose
'SELECT APPROACH', select the desired approach from the list shown, and press the ENT Key. Select the
desired transition, then activate the approach using the ENT Key.
To activate a new approach to a different airport, press the Direct-to Key and select the desired airport using
the FMS Knobs. Press the ENT Key to accept the selected airport, then follow the steps in the preceding
paragraph to select an approach for the new airport.
