TM 1-1510-218-10   3C-29 If FMS 1 is selected as the primary source, the FMS mode is annunciated in white below the primary navigation  source.    The  FMS  1  modes  are    NONE, APPR,  ENRT, OCNC, or  TERM.    The  FMS  mode  will flash     for     10     seconds     starting     1     mile     prior     to transitioning   into   APPR   mode.      When   the   mode   is NONE or ENRT, the annunciation field will be blank. If  the  FMS  2  course  is  selected  as  the  primary source, the FMS mode is annunciated in white below the  course  source.    The  FMS  2  course  modes  are ENRT, APPR, or TERM.  The FMS mode will flash for 10 seconds during the transition from TERM to  APPR.   When the mode is ENRT, the annunciation field will be blank. (9)   FMS  Flight  Modes.    If FMS 1 is selected as the primary source, the FMS mode is annunciated in white   below  the  primary  navigation  source.    The FMS  1  modes  are   NONE,  APPR,  ENRT,  OCNC,  or TERM.      The   FMS   mode   will   flash   for   10   seconds starting 1 mile prior to transitioning into APPR mode.   When the mode is NONE or ENRT, the annunciation field will be blank. If  the  FMS  2  course  is  selected  as  the  primary source, the FMS mode is annunciated in white below the  course  source.    The  FMS  2  course  modes  are ENRT, APPR, or TERM.  The FMS mode will flash for 10 seconds during the transition from TERM to  APPR.   When the mode is ENRT, the annunciation field will be blank. (10)   Data Selection Display (Navigation Data). The    DATA   switch   on   the   control   panel   provides sequential  selection  of  OFF,  GS,  TAS,  TTG,  ET,  or OFF  (no  navigation  data  displayed)  from  the  onside FMS.    The  selected  data  is  displayed  in  white  in  the lower right-hand corner of the display.  When the data is invalid, the digital value is replaced with red dashes.   If the data is unavailable, the data value is blanked. (a)   FMS -800  Operation.  OFF, GS, AS, TTG, and ET are valid data displays for the FMS-800. (b)   KLN  90B  Operation.  OFF, GS, and TTG are valid data displays for the KLN 90B. (11)   Course  Pointer.    The  selected  course  is shown by the relationship of the solid single bar arrow (pointer)   with   respect   to   the   compass   card   and  is repeated  numerically  in  the  upper  right  corner.    The course pointer is white for all navigation sources.  The digital course readout and course needle change by 1 increments   and   rotate   such   that   the   needle   head points to the selected primary course on the compass. (12)   Wind  Direction.    The  MFD  displays  wind velocity  (knots)  and  direction  (degrees)  on  the  bottom of the MFD in green below the label WIND.  If no wind data  is  available,  the  data  will  be  blank.    If  the  wind data is invalid, the data will be dashed red. (13)   Compass   Rose   (360°).      The   compass rose provides a graphical representation of the current heading    of    the    aircraft.        It    is    a    full    360    rose approximately 3 inches in diameter with   N,  E,  S, and W designating the cardinal points and numerics at the 30 points.  Aircraft heading is read against the lubber line.    Major  division  marks  are  every  10  and  minor division marks are every 5 on the compass rose.  The compass  card,  lubber  line,  and  reference  lines  are white. (14)   Bearing  Pointer.    The  bearing  source is selected  by  the  bearing  switch  on  the  control  panel.   The  bearing  arrow  is  a  solid  cyan  line  with  an  open arrow   extending   through   the   aircraft   symbol   to   the minor  tick  marks  on  each  side  of  the  compass.    The arrowhead points to the compass location corresponding to the bearing of the station. (15)   Compass Benchmark. A     compass benchmark    surrounds    the    compass    rose.        The benchmarks   are   white   triangle   marks   located   every 45  except  at  360 along the outside of the compass rose. (16)   Distance    of    Bearing    Source.        When distance  is  available  for  the  selected  bearing  source, the distance source and the distance in nautical miles to   the   NAV   source   are   displayed   in   the   upper   left corner of the MFD.  When the bearing source is FMS, the   active   waypoint   is   displayed   as   the   distance source.    If  the  bearing  source  is  VOR,  DME  will  be displayed as the distance source. NOTE If  an  offside  FMS  is  selected  for  bearing data/distance and it is not activated as the primary   NAV   source   on   the   off-side,  the distance/bearing   information   will   not   be displayed.  This is caused by the method of data importation into the EHSI displays.  If the    offside    FMS    data    is    required,    the offside    primary    NAV    source    must    be selected. The distance readout displays tenths of a mile up to 99.9 nm, and above 99.9 nm it displays whole miles.   If VOR is the selected course source and the VOR is in  DME  hold  mode,  a  cyan   H  is  annunciated  to  the right of the DME distance.
