TM 1-1510-225-10 3B-76 The  bank  command  limit  is  used  by  the  FMS guidance  function  to  limit  FMS  commanded  banks  to the  entered  threshold.    Turn  anticipation  for  waypoint sequencing along the flight plan is adjusted according to the limit specified to minimize overshoot conditions. 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,   first   press   the   mission (MSN)   function   key   on   the   CDU.      Then   select   the Oceanic   line   key   to   display   the   Oceanic   Reporting page.    Refer  to  Figure  3B-39  and  Table  3B -30.  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.
