TM 1-1510-225-10 3B-67 pressing   its    adjacent   line   key   and   the   CDU   will immediately    return    to    the    original    page    with    the waypoint inserted in the desired location.  A frequency or station channel will only be displayed if the waypoint identifier is associated with a navigation radio beacon.   Possible   types   of   waypoints   include   VOR,  V /T   (for VORTAC),  TCN  (for  TACAN),  V/D (VOR-DME), NDB, N/D (for NDB-DME), FIX, APT (for Airport), and DME. Figure 3B-31.  Waypoints With Duplicate Identifiers Table 3B-22.  Waypoints With Duplicate Identifiers NO. DESCRIPTION/FUNCTION 1 NAV   aid   Frequency   or   channel   (if   an NDB, VOR, DME, or TACAN). 2 Signifies   that   the   displayed   waypoints are numbers 13-14 of a total of 17. 3 Line   Select   Keys   1   and   3   enter   the adjacent    waypoint    into    the    originating page. 4 Selects the waypoint and enters it on the originating page. 5 Waypoint’s latitude and longitude. 6 Waypoint ID, Country code and type. The  title  line  displays  the  number  range  of  the displayed duplicate identifiers (i.e., 1-2, 3-4, 5-6, etc.) and  the  total   number  of  duplicate  identifiers  for  the entered  waypoint.    The  scratchpad  retains  the  original waypoint   identifier   entry   until   a   duplicate   waypoint identifier has been selected. The   information   line   will   display   SEARCH   IN PROGRESS   when   a   search   for   duplicates  is  being conducted.        If    a    search    is    interrupted,    SEARCH FAILED  will  be  displayed.   An  interruption  of  a  search can  be  caused  by  removal  of  the  cartridge,  a  data receptacle failure, or bus controller swap. A listing of the country codes is provided in Table 3B-23.  This list is not meant to be comprehensive or current,     because     the     country     identifiers     change frequently.        Refer    to    ICAO    Document    No.    7910, Location  Indicators,  for  a  current  listing.    The  country code ** is used for used defined waypoints. (g)  Flight Plan Waypoint Attribute Indicators.    The  right  side  of  the  FPLN  page  shows any   special   attributes   that   have   been   assigned   to waypoints  in  the  flight  plan.    These  provide  a  quick reference  for  the  pilot  and  are  also  indicated  on  the individual  FPLN  WPT  pages  where  selection  of  the adjacent   line   key   provides   instant   access   to   the respective  pattern  or  other  defined  function.    These attributes   may   be   deleted   by   entering   a    –   in   the scratchpad   and   selecting   the   line   key   next   to   the attribute to be deleted.   This feature enables the crew to  delete  maneuvers  without  leaving  the  FPLN  page.   If  more  than  one  attribute  is  displayed,  the  right-most attribute  will  be  deleted  first  (e.g.,  if  VH  is  displayed, the   H   will   be   deleted   first).      Table   3B-24   lists   the attribute designators and their meanings.
