Approach Notes

Unnamed turn points, intersections, and bearing/distance waypoints: Idents for unnamed turn points, intersections, or bearing/distance waypoints (other than VHF navaid distance/bearing), that are not coincidental with named waypoints, are constructed by using the ident of the nearest navaid together with the distance (rounded to whole miles). If the distance is less than 100 nm, the distance follows the navaid ident. If the distance is 100 nm or more, the last two digits of the miles are placed in front of the navaid ident. For example:

Phase II GPS Approaches

These are most often used for identifying bends in airways that occur at unnamed positions and other en route uses. It is unlikely that you will often see this convention used to name any approach waypoints, but you will occasionally.

GPS equipment may be used as the primary IFR flight guidance during a non-precision approach without actively monitoring the applicable navaid(s) which define the approach being used. However, the traditional ground-based navaid(s) required for the published approach and alternate should be operational and the associated avionics installed and operational. The approach should be requested and approved by its published name, such as “NDB Runway 24.” Modification of the published instrument approach name is not required.
