Basic Operation
6. When LOTKE (the FAF) becomes the active waypoint, the glideslope flag will be removed and the
glideslope will become active. Capture the glideslope as you would an ILS glideslope.
7. As you cross LOTKE, the destination sequences to the MAP (“RW31”, the runway threshold). With the
needle on the external CDI (or HSI) centered, fly toward the MAP, observing the altitude minimums
dictated by the approach plate.
8. When viewing the Map Page, you’ll note that the final course segment is displayed in magenta (the
active leg of the flight plan always appears in magenta).
9. As you approach the MAP, a waypoint message (“NEXT TRK 312°”) appears on the bottom of the
screen.
10. At the Decision Height/Decision Altitude (DH/DA), initiate the missed approach, if necessary. Once
the GNS 480 crosses the MAP (defined as the runway end waypoint), the GNS 480 will automatically
sequence to the first leg of the missed approach.
NOTE
: For missed approaches with heading legs, fly manually until the first active course leg is
reached, as described in earlier sections.
11. Fly the guidance provided by the GNS 480 to the ARTTY intersection and hold.
Flying the LP Approach
An LP approach is flown the same as an LPV approach, except that vertical guidance is not provided. Angular
scaling is similar to a localizer approach. Most LP approaches have step down altitudes associated with them.
1. Within 30 nautical miles of the destination, the GNS 480 switches from en route mode to terminal
mode and the CDI scale transitions from 2.0 to 1.0 nautical miles, full scale deflection.
2. As you approach the IAF, a turn direction message appears on the bottom of the screen.
3. As the distance (DIST) to the IAF approaches zero, the message is replaced by a time to turn advisory
that counts down 10 seconds prior to the turn.
