Flying a RNAV GPS approach with vertical guidance (SBAS Only):
1) Arm flight director modes for a RNAV GPS approach with vertical guidance:
a) G3X: Press the CDI SRC Softkey until GPS is the selected navigation
source.
b) EXTERNAL NAVIGATOR: Select the Runway 35R LPV approach for
KCOS. Load and activate the approach into the flight plan.
2) GMC 305: Press the APR Key once clearance for approach has been
received. GPS Approach Mode is activated and Glidepath Mode is armed.
Or: Press the AP APPR Softkey once clearance for approach has been received.
GPS Approach Mode is activated and Glidepath Mode is armed.
3) Once the glidepath is captured, Glidepath Mode becomes active. The flight
director now provides guidance to the missed approach point.
4) There are two options available at this point, as the autopilot flies the
approach:
• Push the AP DISC Button at the decision height and land the aircraft.
• Use the TO/GA Button (GMC 305 only) to execute a missed approach and
apply TO/GA power.
• Push the AP DISC Button at the decision height to execute a missed
approach and apply go-around power.
