approach:
a) Make sure GPS is the selected navigation
source (use
CDI Softkey to change navigation
source).
b) Load the Runway 29R LPV approach for KFAT
into the flight plan.

2) Press the APR Key once clearance for approach
has been acquired. GPS Approach Mode is
activated (provided the crosstrack error is less
than 2 nm) and Glidepath Mode is armed.
3) Once the glidepath is captured, Glidepath Mode
becomes active.
4) There are two options available at this point, as
the autopilot flies the approach:
• Push the AP DISC Switch at the Decision
Height and land the aircraft.
• Use the
GA Switch to execute a missed
approach.
