TM 1-1510-218-10 3C-100 On the Navigation Configuration page, the crew may enter parameters for the waypoint alert and cross track   deviation   threshold.      Entering   the   number   of seconds    for    the    waypoint    alert    will    set    an    alert anticipation that activates external waypoint annunciations   on   capsule   lights   or   flight   instrument displays the specified time before a waypoint transitions. For    cross    track    alerts,    entering    a    value    (in nautical   miles)   for   the   cross   track   annunciation   will trigger an XTK ALERT when the cross track deviation exceeds  the  entered  threshold  value.    This  alert  is inhibited during turns from one leg to the next. (e)   Selection   of   Flight   Mode.      On   the Navigation   Configuration  page,  the  current  mode  of flight can be selected.  The mode selection affects the lateral  steering  scaling  and  integrity  determination  of the  GPS  and  INU/GPS  navigation  solutions.    When powered  up,  the  FMS  defaults  to  TERMINAL  mode until  the  aircraft    has   left   the   30   nm   terminal   area around  the  origin  airport.    When  the  aircraft  comes within   30   nm   of   the   destination   airport,   the   FMS automatically transitions back to the TERMINAL mode.   When   the   aircraft   reaches   the   Final   Approach   Fix (FAF) of an approach,     the     FMS     automatically transitions to the APPROACH mode.  Each flight mode can     be     manually     overridden     on     the     Navigation Configuration page. (7)   Oceanic  Reporting  Function.    The  FMS- 800  provides  an  oceanic  flight  position  reporting  and trip  log  function  to  simplify crew procedures for these tasks. (a)   Data  Access  and  Display.    To  view the  Oceanic  Mission  page,  press  the  mission  (MSN) function key on the CDU.  Select the Oceanic line key to   display   the   Oceanic   Reporting   page.      Refer   to Figure 3C-45  and  Table  3C-36.  This page shows the current  flight  plan  waypoints  in  sequence  with  each waypoint’s   respective   ETA   (for   future   waypoints)   or Actual  Time  of  Arrival  (ATA)  (for  history  waypoints).   These  may  be  read  and  reported  without  additional paging.      A   typical   position   report   includes   the   time passing the most recent reporting point and the ETA’s of    the    next    three    reporting    points    in    UTC.        The calculation  of  the  active  waypoint’s  ETA  is  based  on current    true    airspeed    and    wind.        All    subsequent waypoint ETA’s are calculated using current airspeed and either the current default or pilot-entered leg wind for subsequent legs. Each time a waypoint is passed into history, the ATA is recorded by the FMS.  To view this trip log of waypoint passage times, scroll the list upward to view the  history  waypoints  and  their  ATA’s.    If  waypoints have been bypassed via a Direct-To operation, dashes are displayed for the ATA.
