Unnamed turn points, intersections, andbearing/distance waypoints: Idents for unnamed turnpoints, intersections, or bearing/distance waypoints(other than VHF navaid distance/bearing), that arenot coincidental with named waypoints, areconstructed by using the ident of the nearest navaidtogether with the distance (rounded to whole miles).If the distance is less than 100 nm, the distancefollows the navaid ident. If the distance is 100 nm ormore, the last two digits of the miles are placed infront of the navaid ident. For example:NAVAID DISTANCE IDENTINW 18 INW18CSN 106 06CSNTCS 89 TCS89These are most often used for identifying bends inairways that occur at unnamed positions and other enroute uses. It is unlikely that you will often see thisconvention used to name any approach waypoints,but you will occasionally.Phase II GPSApproachesGPS equipment may be used as the primary IFRflight guidance during a non-precision approachwithout actively monitoring the applicable navaid(s)which define the approach being used. However, thetraditional ground-based navaid(s) required for thepublished approach and alternate should beoperational and the associated avionics installed andoperational. The approach should be requested andapproved by its published name, such as “NDBRunway 24.” Modification of the publishedinstrument approach name is not required.9-89Approach Notes
