Once a departure is activated, the G1000 Course Deviation Indicator (CDI) full scale deflection is set to 0.3 

nm.  The CDI scale changes to 1.0 nm (terminal mode) then ramps up to 2.0 nm (enroute mode) at 30 nm 
from the departure airport.  When 31 nm from the destination, the CDI scale smoothly transition from 2.0 nm  
back to 1.0 nm (terminal mode).  At 2.0 nm before the FAF during an active approach, the CDI scale transitions 
down further based on the type of approach activated (LNAV, LNAV/VNAV, LPV).  When  a missed approach is 
activated, the CDI is set to 0.3 nm.  See the Flight Instruments Section for more details on CDI scaling.

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.

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.

Do not attempt to reactivate the current approach prior to crossing the missed approach point 

(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.
