TM 1-1510-218-10 3-48   8:LAS   9:DAG V25L-KLAX 10 ELMOO-i 11 LAX18 17:KLAX CRSR ENR - LEG Figure 3-62.  FPL 0 with Approach   8:LAS   9:DAG CHANGE APR? 10 ELMOO-i 11 LAX18 17:KLAX CRSR ENR - LEG Figure 3-63.  Change the Approach 3.   If   the   CLR   button   is   pressed   while   the cursor  is  over  the  approach header, it will change  to  read  DELETE  APR?.    Refer  to Figure  3-64.  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 3-64.  Delete the Approach ar.    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. (2)   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. (3)   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. (4)   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 3-65. Figure 3-65.  Super NAV 5 Page (5)   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 HSI.  If DTK is shown on the screen, this value will  flash  when  the  external  selected  course  does  not match the DTK within 10. 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.
