TM 1-1510-225-10 3B-66 (e)  Modifying  Waypoint   Locations.    If  a bearing/distance (e.g., 050/23)     is     inserted     at     a waypoint    identifier,    that    waypoint    is    offset    by    the bearing and distance, and displayed in the scratchpad with the bearing and distance offset applied.  Refer to Figure  3B -29   and   Table   3B-20.    If  the  bearing  and distance  is  applied  at  any  other  type  of  waypoint  (e.g. latitude/longitude),  the  FMS-800  computes  the  offset latitude and longitude of the position and displays it in the   scratchpad.      Refer   to   Figure   3B -30   and   Table 3B-21.  In either  of the two case stated above, the new waypoint can now be inserted into the fight plan.  If the original    waypoint    needs    to    be    deleted,    follow    the procedure in Paragraph 3B -19e(3)c. Figure 3B-29.  Modifying Waypoint Identifier Locations Table 3B-20.  Modifying Waypoint Identifier Locations NO. DESCRIPTION/FUNCTION 1 Enter   the   bearing/distance   offset   into   the scratchpad. 2 Apply the offset to BRL. 3 Ensure there is a new waypoint offset to the desired   bearing/distance  displayed  in  the scratchpad.      It   may   b e  inserted  into  the flight plan as desired. Figure 3B-30.  Modifying Latitude / Longitude Locations Table 3B-21.  Modifying Latitude / Longitude Locations NO. DESCRIPTION/FUNCTION 1 Enter    the    bearing/distance    offset    in    the scratchpad. 2 Apply the offset to a lat-long. 3 The  computed  lat-long  is  displayed  in  the scratchpad  and  available  for  insertion  into the   flight   plan   (original   waypoint   may   be deleted manually if desired). The bearing is referenced to the Station declination,  for  a  waypoint  that   is  a  VOR,  VORTAC, VOR-DME, or TACAN, and for all other waypoints. (f)   Waypoints   with   Duplicate   Identifiers.   If a waypoint identifier is entered which is duplicated in another area of the world, the Select Waypoint page is automatically accessed and displays the data for up to 20  waypoints  having  that  identifier.    Refer  to  Figure 3B-31 and Table 3B-22.  If more than two do exist, the pages can be scrolled for viewing.  Up to 19 duplicate identifiers   will   be   searched   from   the   primary   ICAO database on the cartridge.  One duplicate identifier will be    searched    from    the    User    Waypoint    list.        The identifiers are ordered from closest to present position to  furthest  from  present  position  when  the  navigation solution   is   valid.      Select   the   desired   waypoint   by
