TM 1-1510-225-10 3B-93 (3)   Flight     Director     and     Autopilot     Lateral (Bank) Steering.  Using the Flight Director or autopilot, the  FMS  can  steer  the  aircraft  directly  through  all  of the  possible  flight  plan  maneuvers  including  holding patterns, MFP’s, SID’s, STAR’s, and FMS approaches.   This    interface    also    enables    the    FMS    to    limit    the commanded  bank  angle  to  the  value  specified on the Navigation Configuration page. The   FMS   provides   a   heading   submode   (FMS heading)   that   allows   the   crew   to   temporarily   fly   to selected    headings    while    still    using    FMS    waypoint navigation.  For those aircraft equipped with Electronic Flight Instrument Systems (EFIS), select FMS heading mode  by  pressing  the  HDG  knob  and  adjusting  the knob  to  the  desired  heading.    The  FMS  will  provide commanded bank to the selected heading indefinitely or until the heading is adjusted in such a way as to re- intercept the previous course. (a)  Additional     Displays     on     Electronic Flight  Instrument  Systems.    For  those  aircraft  which are  equipped  with  an  electronic  flight  display  system (EFIS or FDS), additional displays may be provided as shown in Figure 3B -57.  The following  additional data is  available  for  display  from  the  FMS  on  the  primary flight instruments: 1.   Eight  future  flight  play  waypoints (including the active) to give advance  notice  of  impending  leg changes and relative distances to future waypoints when the electronic HSI is in MAP mode. 2.   Identification of the type of waypoint  (i.e.,  NAV  aid,  intercept, standard    waypoint,    airport,    etc.) and label identifier. 3.   Ground speed. 4.   True Airspeed. 5.   Wind direction and speed. 6.   Time to go. 7.   Bearing to Waypoint. 8.   Elapsed Time. (4)   FMS    Heading    Mode    Overview.        The FMS-800 provides heading guidance for radar vectoring   to   intercept   a   final   approach   course   of   a published  GPS  approach,  without  the  pilot  needing  to deselect  and  reselect  the  flight  control  system  NAV mode. (a)  Activation    of    FMS    Heading   Mode.   When commencing a published GPS approach, if ATC gives  instructions  to  follow  radar  vectors  to  intercept the final approach course, select DIRECT TO the FAF.   The   message   FINAL   CRS   XXX  will  appear  in  the CDU  scratchpad.    Select  line  key  L1  on  the  CDU to insert   that   final   approach   course   extension   as   the currently displayed FMS course.  Press the  HDG knob on the FDS control panel to activate the FMS Heading Mode, and select the desired heading to intercept the final  approach  course.    The  FMS  roll  command  will guide  the  aircraft  to  acquire  and  hold  the  displayed heading and any subsequent desired heading entered by   the   pilot   on   the   FDS   control   panel.      The   FMS Heading   Mode   will   continue   to   guide   to   the   FDS selected  heading  as  long  as  the  heading  is  steering away  from  the  flight  plan  course.    When  the  selected heading is steering towards the flight plan course, the FMS Heading Mode will automatically cease when the course    can    be    captured    by    normal    FMS    lateral guidance. (b)  Termination  of  FMS  Heading  Mode.   With no further action on the part of the pilot, the FMS will  automatically  drop  the  FMS  Heading  mode  and recapture   the   final   approach   course   when   the   final course is intercepted, without overshoot.  To manually terminate  the  FMS  Heading  mode,  select   DIRECT  / TO  the  FAF  or  any  other  waypoint.    The  FMS  will immediately resume FMS course guidance.
