When flying a GPS approach with your students, build upon what you taught about GPS approach designs. Flying a GPS approach is challenging; however, your students will realize more potential of GPS and be better prepared for GPS approaches when you have briefed them on a variety of important GPS approach information. You’ll familiarize yourself with the critical information that you need to share with your students by exploring the following:
- Understanding Alternate Airport Navigation
- Understanding GPS Monitoring an Approach
- Simulating a GPS Approach
Understanding Alternate Airport Navigation
When using a non-WAAS GPS for primary navigation, you must also have approved and operational alternate means of navigation appropriate for the flight. In other words, you must be able to complete the flight, start to finish, using non-GPS navigation. If you file an alternate destination airport, the alternate must include a non-GPS approach, and the aircraft must be equipped to fly that approach. In contrast, if you are using a WAAS GPS, the alternate airport can just have GPS approaches.
WAAS GPSで無い場合は、最初から最後案で、そしてAlternateまで、GPS以外でも飛行が可能で有る必要があります。
Understanding GPS Monitoring an ILS Approach
The GPS capability of some units can be used to monitor the progress of ILS approaches. To activate and fly an ILS approach with vectors-to-final:
- Ensure that the localizer is tuned in and identified, even if the GPS navigation system does it automatically.
- Change the navigational source from GPS to localizer. The localizer, not the GPS, is now your HSI navigation source.
Navigate using the localizer and glide slope. The GPS unit continues to provide helpful GPS information, such as distance and time to the outer marker or MAP.

Simulating a GPS Approach
The following simulation guides you through the steps used to fly a GPS approach. In this simulation, you will learn how to:
- Recognize when LPV minimums are available on a given instrument approach chart.
- Ensure that the GPS approach waypoints match those on the instrument approach chart.
- Recognize how the GPS changes from enroute mode to terminal mode to approach mode before and during an approach.
This simulation consists of five parts:
- Recognizing LPV Minimums within a Chart
- Matching Flight Plan Data
- Recognizing Approach Mode
- Recognizing LPV and ILS Approaches
- Simulating a GPS Missed Approach
