TM 1-1510-225-10 3D-47 available,     and     RAIM     is     currently     available,     the KLN 90B   will   change   the   GPS   APR   annunciator   to read   ACTV   and   the   status   line   will   indicate   APR.   Refer  to  Figure  3D-66.  At this time, the KLN 90B will also start to change the CDI scale factor.  By the time the  aircraft  reaches  the  FAF,  the  GDI  scale  factor  will be down to ± 0.3 nm full-scale deflection. NOTE Some approach procedures require adding up several along track distances to be able to identify a step down fix. (7)   A  step  down  fix  may  not  be  included  in the   list   if   waypoints   are   provided   in   the   database.   Identify  this  point  by  using  the  along  track  distances given    in    the    profile    view    of    the    approach    plate.   Remember, in the leg mode, the distance given by the KLN 90B is the distance to the next point (in this case, the  MAP),  not  the  distance  from  the  last  point  (the FAF). Figure 3D-66.  GPS Approach Mode Active (8)   The KLN 90B will again provide waypoint alerting as the missed approach point is approached.   This is shown on the Super NAV 5 page as a flashing active   waypoint   identifier,   as   well   as   the   external flashing waypoint annunciator.  If the auto scale factor was  chosen  for  the  Super  NAV  5  page,  the  airport diagram will be visible when the aircraft is within 5 nm of the airport.  More detail is shown as the aircraft gets to within 1 nm of the airport. NOTE If ATC instructions for the missed approach  are  different  from  the  published procedure, it is always possible to select a different   DIRECT   TO   waypoint   from   the default DIRECT TO waypoint. (9)   If a missed approach is required, the KLN 90B  will  not  automatically  sequence  past  the  missed approach   point.      To   perform   the   published  missed approach procedure, press the   D    button to bring up the  Direct  To  page.    The  default  waypoint  will  be  the first    waypoint    of    the    published    missed    approach procedure.    Confirm  this  waypoint  as  the  DIRECT  TO waypoint and press the ENT button. (10)Upon reaching the first point, the KLN 90B will   sequence   to   the   next   waypoint   in   the   missed approach procedure. g.  Off Airport Navaid Approach. 1.   Load  the  approach  into  the  flight  plan.  If there  is  only  one  IAF,  the  KLN  90B  does not  give  the  option  to  choose  an  IAF.    If there is no active flight plan (i.e., direct to navigation is being used without an active flight  plan),  the  KLN  90B  will  ask  to  add the  airport  and  the  approach  to  FPL  0.   Refer to Figure 3D-67. V22-KCVN PRESS ENT TO ADD KCVN AND APPR TO FPL 0   APPROVE? CRSR ENT Figure 3D-67.  Loading the Approach 2.   If ATC then clears the  aircraft  to  the  IAF, with the Super NAV 5 page displayed, pull out the right inner knob and scan through the   active   flight   plan.      Once   the   IAF   is displayed  in  the  scanning  window,  press the    D    button and then the   ENT button to initiate a direct to operation to the IAP. 3.   At a distance of 4 nm to the IAF, the KLN 90B will give the message, IF REQUIRED SELECT OBS. (1)   This message provides a reminder that to fly   a   course   reversal,   the   OBS   mode   needs   to   be selected.  If the aircraft is approaching the IAF from  an area   where   there   is   no   need   to   perform   a   course reversal, ignore the message.  A NoPT arrival sector is not stored in the database, so it is not possible for the KLN   90B   to   know   that   the   course   reversal   is   not required.  Therefore, the KLN 90B will always give the message  whenever  a  waypoint  could  be  used  for  a course  reversal.    If  the  aircraft  is  approaching  from  a
