DESCRIPTION/FUNCTION 1 Select FPLN. 2 Sequencing mode toggles between AUTO, FLYOVER, and MAN sequencing modes. 3 Waypoint attached attribute. 4 Waypoint sequence number. 5 Outbound    course    and    distance    to    next waypoint. 6 Active waypoint. 7 Course at active waypoint. (b)   When a waypoint becomes a history waypoint, a  # following the waypoint number indicates that   the   waypoint   is   no   longer   an   active   or   future waypoint. (3)   Flight Plan Waypoints. (a)   Numbering of Waypoints. A maximum   of   60   active   waypoints   and   39   history waypoints are allowed in the flight plan at a time.  The flight   plan   waypoints   are   numbered   sequentially   in increments of one, from 01 to 99, with waypoint 00 as the initial history waypoint.  If a waypoint is added past 99,   the   numbering   starts   at   01   and   uses   the   first available  waypoint  number  not  used  by  a  history  or active    waypoint.        Non-SID,    STAR,    approach,    or alternate    flight    plan    waypoints    that    are    inserted between   existing   waypoints   receive   an   alphabetical suffix.    If  a  SID,  STAR,  approach,  or  alternate  flight plan  is  inserted  into  the  flight  plan,  no  alphabetical suffix    is    used.        The    SID,    STAR,    and    approach waypoints  are  numbered  in  the  normal  method  with subsequent waypoints automatically renumbered.   These  features  prevent  the  duplication  of  a  waypoint number within the flight plan.   (b)   Inserting   Waypoints   in   Sequence.   When the flight plan has been erased, the Start 1 page starting position is inserted as the first history waypoint and the Flight Plan page indicates  *END in lieu of the active     waypoint.          Refer     to     Figure     3C-33     and Table 3C-24. When a waypoint is inserted before ^H END, when ^HEND    is    on    the    last    line,    the    Flight    Plan    page automatically  scrolls  as  necessary  to  keep  the ^H END indicator  in  view  on  the  bottom  line.    This  permits  the pilot to enter a long sequence of points without having to    manually    scroll    the    page.        The    FPLN    FULL message  will  appear  in  the  scratchpad  if  there  is  an attempt to load a 61^st waypoint. (c)   Inserting   and   Deleting   Intermediate Waypoints.      In   most   cases,   the   waypoints   may   be inserted  or  deleted  between  any  two  waypoints  in  the flight  plan.   When  waypoints  are  inserted,  succeeding waypoints   are   automatically   moved   down   the   list.   Upon    insertion,    the    new    waypoint    assumes    the number  of  the  immediately  preceding  waypoint  and adds  an  alphabetical  suffix  (e.g.,  03A,  03B,  etc).    An exception to this would be when a waypoint is inserted between  waypoints  that  already  have  an  alphabetical suffix.  The next character in sequence would be used as  the  next  suffix.    If  lettering  goes  as  high  as  Z  and there   is   an   attempt   to   insert   another   waypoint,   the RENUMBER  FPLN  scratchpad  message  will  occur.   When    the    waypoints    are    deleted,   the    flight    plan automatically eliminates all holes by moving waypoints up  the  list  as  required.    The  waypoint  numbers  being out   of   the   normal   sequence   can   identify   deleted waypoints.    There  are  three  exceptions  to  the  above waypoint   statements.      Refer   to   Figure   3C-34   and Table 3C-25.
