TM 1-1510-218-10 3-45 If  any  of  these  conditions  are  not  met,  the  KLN 90B will not transition to the approach active mode and a missed approach will be required if the conditions do not  change  before  reaching  the  FAF.    If  all  of  these conditions  are  met,  the  CDI  scale  factor  will  start to change  to  ±  0.3  nm  and  the  external  annunciator  will indicate ACTV. (5)   At  the  FAF  (position  D),  the  CDI  scale factor will be at ± 0.3 nm and will remain at this scale factor until the approach mode is canceled by pressing the external  GPS  APR button to  change to the  ARM mode, by initiating a direct to operation, or by changing to the OBS mode. It   is   not   approved   to   conduct   the   final portion  of  the  approach  unless  the  KLN 90B is in the approach active mode. (6)   Fly to the missed approach point (position E).  The  KLN  90B  will  not  automatically  sequence  to the  next  waypoint,  it  must  be  manually  selected.    By default, the KLN 90B will nominate the first waypoint of the  published  missed  approach  procedure  when  the     D        button  is  pressed  and  the  active  waypoint is the MAP. (7)   If necessary, conduct the missed approach  procedure.    Always  refer  to  the  approach chart when conducting a missed approach.  The KLN 90B does not include headings and altitude restrictions common  to  missed  approach  procedures.    The  OBS mode is usually needed at some point during a missed approach   and   is   always   required   to   fly   a   holding pattern (position F). ao.  Selecting   An   Approach.    Approaches  are selected   from   the   APT   8   or   ACT   8   page   for   the destination airport. NOTE Approaches  can  only  be  entered in FPL 0, the  active  flight  plan.    If  the  KLN  90B  is turned   off   for   more   than   5   minutes,   the approach is deleted when power is turned back on. 1.   Turn to the APT or ACT pages and select the    destination    airport    using    the    right cursor inner and outer knobs. 2.   Use the right inner knob to turn to the APT or  ACT  8  page.    The  APT  8  page  can  be reached   by   turning   the   right   inner   knob one step counterclockwise from the APT 1 page. 3.   Turn  the  right  cursor  on.    The  right  cursor comes up on the first approach in the list of  approaches.    Use  the  right  outer  knob to     move     the     cursor     to     the     different approaches.      Refer   to   Figure   3-57.      If there are more than five approaches to an airport, move the cursor down to scroll the other  procedures  into  view  by  rotating  the right inner knob clockwise.
