On a non-overlay approach, such as a localizer back-course, can the Garmins be used legally for waypoint reference?
For example, onthe runway 11 localizer back-course at Alton IL (ALN), which I happen to be flying this evening on some recurrent training, the FAF is determined either by a radial from the STL VOR or DME from the ILS “end” (I-ALN). I’d assume that the Garmin will track (for reference) when I come to the FAF. However, my assumption is that to be legal, I’d still have to use the VOR radial, or do a direct-to the ILS (I-ALN) waypoint if that can be done.
- Am I correct on this?
- Will the Garmins do a direct to the ILS waypoint? (On the simulator, it seems willint to do that - calls it an intersection.)
Any help and resulting avoidance of embarrasment with my instructor would be greatly appreciated.
