TM 1-1510-218-10 3C-88 2   No    waypoints    can    be    inserted between any two-history waypoints. 3   The last history waypoint (waypoint 00) cannot be deleted. Sixty    waypoints    is    the    maximum    number    of waypoints allowed in the active flight plan.  The FPLN FULL   message   will   appear   in   the   scratchpad   if   an insertion of a 61^st waypoint is attempted. (d)   Renumbering Flight Plan Waypoints.   After inserting or deleting waypoints, there becomes a requirement  to  renumber  the  flight  plan  to  remove waypoints with alphabetical suffixes.  Access the Flight Plan   Edit   2   page   and   select   the   RENUMBER  line select   key   (requires   confirmation).      This   causes   all future    flight    plan    waypoints    to    be    renumbered    in sequence  without  alphabetic  suffixes,  starting  at  the active waypoint number.  The active waypoint and the history waypoints are not renumbered. (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  3C-35   and   Table  3C-26.    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   3C-36   and   Table 3C-27.    In  either  of  the  two  cases  stated  above,  the new waypoint can now be inserted into the flight plan.   If the original waypoint needs to be deleted, follow the procedure in Paragraph 3C-25.e.(3)(c). Figure 3C-35.  Modifying Waypoint Locations Table 3C-26.  Modifying Waypoint Identifier Location Procedure NO. DESCRIPTION/FUNCTION 1 Enter   the   bearing/distance   offset   into   the scratchpad. 2 Apply the offset to BRL. 3 Ensure  that  there  is  a  new  waypoint  offset to the desired bearing/distance displayed in the scratchpad.  It may be inserted into the flight plan as desired. Figure 3C-36.  Modifying Latitude / Longitude Locations Table 3C-27.  Modifying Latitude / Longitude Location Procedure 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.
