ok, there it is, plain and simple straight out of the AIM. it says to go outbound for the specified distance instead of time. I am not sure why but it seems to depend on who you talk to at my school, but some say 1min outbound (not sure why the AIM says otherwise) and others like myself say go for the distance.5. Distance Measuring Equipment (DME)/ GPS Along-Track Distance (ATD). DME/GPS holding is subject to the same entry and holding procedures except that distances (nautical miles) are used in lieu of time values. The outbound course of the DME/GPS holding pattern is called the outbound leg of the pattern. The controller or the instrument approach procedure chart will specify the length of the outbound leg. The end of the outbound leg is determined by the DME or ATD readout. The holding fix on conventional procedures, or controller defined holding based on a conventional navigation aid with DME, is a specified course or radial and distances are from the DME station for both the inbound and outbound ends of the holding pattern. When flying published GPS overlay or stand alone procedures with distance specified, the holding fix will be a waypoint in the database and the end of the outbound leg will be determined by the ATD. Some GPS overlay and early stand alone procedures may have timing specified. (See FIG 5-3-5, FIG 5-3-6 and FIG 5-3-7.) See paragraph
1-1-19, Global Positioning System (GPS), for requirements and restriction on using GPS for IFR operations.
i don't know why some people get so confused on this one
