How to Use Flight GPS
Use a flight Global Positioning System to navigate direct to a destination or waypoint. For more complex flight routing, program the flight GPS to fly to multiple waypoints by using the flight plan option. Certified GPS units are appropriate for use with flying an instrument approach into certain airports. Flight GPS units use the array of GPS satellites orbiting the Earth to navigate with precision accuracy.

Turn the "Master Avionics" switch on to provide power to the GPS unit. The flight GPS will go through an automatic self-check procedure to verify the receiver is working properly, acquiring multiple GPS satellites and checking the navigation database. Verify that the flight GPS database is current and legal for your type of flight.

Select the "Flight Plan" button to program multiple waypoints into the flight GPS. "Direct To" navigation is great with one destination and straight line routing. However, a pilot often will have multiple destinations or non-linear routing. In such cases, use the "Flight Plan" menu to enter multiple waypoints to have the flight GPS navigate seamlessly from one waypoint to another.

Enter the "Procedures" button to select an instrument approach at a specific airport. Instrument-rated pilots flying instrument-certified aircraft and instrument-approach certified GPS units can use their flight GPS to fly a GPS approach, when on an instrument flight plan in instrument meteorological conditions.
