Geographic positions, given in degrees of latitude and longitude, used in defining instrument approach procedures (IAP) . Waypoints may be coded in aircraft navigation data bases and depicted on instrument approach charts as either fly-by waypoints (turn anticipation permitted) or fly-over waypoints (turn anticipation not permitted) . Waypoints that define the missed approach point (MAP) and the missed approach holding waypoint (MAHWP) shall be coded as fly-over waypoints.See also: Final Approach Course Fix (FACF) , Final Approach Waypoint (FAWP) , Fly-By Waypoint, Fly-Over Waypoint, Initial Approach Waypoint (IAWP) , Intermediate Approach Waypoint (IWP) , Missed Approach Holding Waypoint (MAHWP) , Missed Approach Turning Waypoint (MATWP) , Missed Approach Waypoint (MAWP) and Downwind Termination Waypoint (DTW)
