outbound ends of the holding pattern. When flying             overlay and early stand alone procedures may have
published GPS overlay or stand alone procedures               timing specified. (See FIG 5-3-5, FIG 5-3-6 and
with distance specified, the holding fix will be a            FIG 5-3-7.) See paragraph 1-1-17, Global Position-
waypoint in the database and the end of the outbound          ing System (GPS), for requirements and restriction
leg will be determined by the ATD. Some GPS                   on using GPS for IFR operations.


                                                       FIG 5-3-5
                                              Inbound Toward NAVAID




NOTE-
When the inbound course is toward the NAVAID, the fix distance is 10 NM, and the leg length is 5 NM, then the end of the
outbound leg will be reached when the DME/ATD reads 15 NM.


                                                       FIG 5-3-6
                                          Inbound Leg Away from NAVAID




NOTE-
When the inbound course is away from the NAVAID and the fix distance is 28 NM, and the leg length is 8 NM, then the end
of the outbound leg will be reached when the DME/ATD reads 20 NM.


                                                       FIG 5-3-7
                                                 GPS/RNAV Holding




NOTE-
The inbound course is always toward the waypoint and the ATD is zero at the waypoint. The end of the outbound leg of the
holding pattern is reached when the ATD reads the specified distance.
