Many pilots who use sophisticated GPS-based navigators have difficulty consistently loading and flying approaches. As I’ve noted elsewhere, pilots who use the vectors-to-final option may find themselves scrambling to comply with a clearance that directs them to a specific fix in the approach. Other pilots fumble with activating an approach, a process that sometimes leads the airplane in an unexpected direction.
Many instructors, myself included, have long advocated using the flight plan page on your navigator to simplify flying instrument approaches (and SIDs and STARs). In fact, the flight plan page or menu is typically the most misunderstood and least-utilized feature of most GPS navigators.
I’ve created a short presentation that guides you through the process of loading (and “activating”) an approach on the Garmin GTN 750. The presentation, Flying an Approach with the GTN 750, is available as a free PDF that you can download from the Aviation Documents folder at my OneDrive page. You can find many more useful, free references there.
The basic technique and principles described in the presentation apply to most IFR-approved GPS navigators, but you should, of course, review the handbook and AFM supplement applicable to the unit in the aircraft that you fly.
After reviewing the presentation, practice with the free simulators available from Garmin and fly with an instructor or safety pilot in VMC before you launch on an actual IFR flight.
