TM 1-1510-225-10 3D-46   8:LAS   9:DAG CHANGE APR? 10 ELMOO-i 11 LAX18 17:KLAX CRSR ENR  -  LEG Figure 3D-63.  Change the Approach 3.     If  the  clear  button  is  pressed  while the     cursor     is     over     the     approach header, it will change to read DELETE APR?.  Refer to Figure 3D-64.  If  ENT is   pressed   now,   the   KLN   90B   will remove the entire approach procedure from the active flight plan.  If the KLN 90B  was  in  the  approach  arm  or  the approach  active  modes,  deleting  the approach  will  cause  the  KLN  90B  to change  back  to  the  en  route  mode.   This  means  the  CDI  scale  factor  will change  back  to  the  default  ±  5.0-nm scale.   8:LAS   9:DAG DELETE APR? 10 ELMOO-i 11 LAX18 17:KLAX CRSR ENR - LEG Figure 3D-64.  Delete the Approach f.    No Procedure Turn Approach. This example    will    show    how    the    KLN    90B    sequences through an approach that does not require a procedure turn.    It  will  remain  in  the  LEG  mode  throughout  the approach. (1)   Load the approach into the flight plan.  At 30    nm    the    KLN    90B    will    automatically    arm    the approach   mode   and   provide   the   message,   PRESS ALT TO SET BARO.  Press the ALT button to bring up the  ALT  page  and  verify  that  the  altimeter  setting  is correct.  At this time, the KLN 90B will change the GDI scale factor to ± 1.0 nm.  The external approach mode annunciator  will  indicate  that  the  approach  is  in  the ARM mode. (2)   As the initial approach fix is approached, the   KLN   90B   will   provide   waypoint   alerting   on   the external   waypoint   annunciator,   as   well   as   on   the screen of the KLN 90B.  Once the IAF is passed, the KLN  90B  will  sequence  to  the  next  waypoint  on  the approach. (3)   Use    of    the    Super    NAV    5    page    is recommended  because  of  its  graphic  presentation  of the aircraft location and the approach course.  Refer to Figure 3D-65. (4)   As    the    aircraft    approaches    the    next waypoint,  the  KLN  90B  will  again  provide  waypoint alerting.  Each time the aircraft passes a waypoint and sequences   to   the   next   waypoint,   the   KLN   90B   will provide  a  message  annunciating  the  new  value  to  set on  the  EHSI.    If  DTK  is  shown  on  the  screen,  this value   will   flash   when   the   external   selected   course does not match the DTK within 10. Figure 3D-65.  Super NAV 5 Page NOTE If the KLN 90B is interfaced with EFIS or an electrically driven mechanical indicator (HSI),  the  external  indicator  will   be driven to  the  correct  value  when  leg  sequencing occurs.  (5)   As    the    aircraft    approaches    the    final approach fix, verify that the LEG mode is selected and that GPS is selected as the primary navigation source. (6)   Two nautical miles from the final approach  fix,  the  KLN  90B  will  make  a  prediction  to see if integrity will be available at the FAF and MAP.  If the prediction indicates that integrity monitoring will be
