TM 1-1510-225-10 3A-53 appear    30    seconds    prior    to    entering    the    holding pattern.        The    display    message    will    change    to HOLDING  after  crossing  the  holding  fix  the  second time. 3   PARALLEL  ENTRY.    This  display message  indicates  that  the  system  will  use  a  parallel entry   into   the   holding   pattern.      This   message   will appear    30    seconds    prior    to    entering    the    holding pattern.        The    display    message    will    change    to HOLDING  after  crossing  the  holding  fix  the  second time. 4   HOLDING.          This     message     is normally displayed while holding. 5   EXIT HOLD. This message indicates  that  the  system  will  exit  the  holding  pattern the next time over the holding fix.  The estimated time en route to the holding fix is also displayed. (f)    DIS.    This  line  displays  the  distance in nautical miles and tenths of nautical miles from the aircraft's present position to the holding fix. (g)   ETE. This line displays the estimated  time  en  route  until  the  next  time  over  the holding   fix   based   on   the   path   around   the   holding pattern. (h)   INBOUND  CRS.    This  line  displays the    inbound    holding    course    (INBOUND    CRS)    in degrees. (i)    GS.      This  line  displays  the  current groundspeed. (j)    WIND.   This line displays the current wind   direction   referenced   to   true   north,   and   wind speed in knots. NOTE The  leg  change  mode  (AUTO  or  MANUAL) will not be displayed while holding. (3)   Navigation   2/4   Page.      Refer   to   Figure 3A-27. (a)   FR,  DIRECT,  HOLD,  PROCEDURE TURN, DME ARC, or PSEUDO VORTAC Line.  Same as in Navigation 1/4 page. (b)   TO, AR, HP, or PT Line.  Same as in Navigation 1/4 page. (c)   NX,  HDG  SELECT,  or  INTERCEPT HDG Line.  Same as in Navigation 1/4 page. Figure 3A-27.  FMS Navigation 2/4 Page (d)   WIND.   The first field in the wind line displays headwind or tailwind in knots preceded by an up   arrow    for    a    tailwind    or    a    down    arrow    for    a headwind.    The  second  field  displays  the  crosswind component in knots followed by a right pointing arrow for  a  left  crosswind  or  a  left  pointing  arrow  for  a  right crosswind. (e)   ETA. This line displays the estimated  time  of  arrival  at  the  last  waypoint  on  the active flight plan. (f)    FUEL. This line displays the estimated fuel that will be remaining at the destination. (g)   TKE.        Track    error    (TKE)    is    the difference  between  the  desired  track  and  the  actual track   in   degrees.      R   (right)   or   L   (left)   is   displayed preceding   the   track   error   in   degrees   to   show   the direction of error in relation to the desired track. (h)   XTK.    Crosstrack  (XTK)  distance  is the lateral displacement of the aircraft in nautical miles and  tenths  of  a  nautical  mile  to  the  left  or  right  of  the desired  track  (125  NM  maximum).    TRMNL,  APRCH, or  ENRTE  will  be  displayed  following  XTK  to  indicate the approach mode that the system is presently using. 1   TRMNL.   TRMNL will be displayed following  XTK  to  show  that  the  system  is operating in the terminal approach mode. 2   APRCH.  APRCH will be displayed following  XTK to show that the system is operating in the approach mode.
