TM 1-1510-225-10 3D-12 Figure 3D-7.  Nearest Airport Page NOTE The  capability  to  display  nearest  airports exists  only  when  the  KLN  90B  is  actually operating in the primary database coverage  area.    For  example,  if  the  KLN 90B contains a North American database it will  not  display  the  nearest  airports  while operating in South America. In    the    event    of    an    emergency,    a    special procedure exists to very quickly get to the beginning of the nearest airport list. 1.   MSG button – Press. 2.   ENT button  – Press. The waypoint page for the nearest airport is now displayed  on  the  right  side.    The  right  inner  knob  may now be used in the normal manner to scan the other nearest airports,  knob  in  the  "out"  position,  or  to  view all eight airport pages for a specific airport, knob in the in position. When     the     nearest     airport     page     is     initially displayed,  NR  1  is  displayed  in  the  upper  right  hand corner  of  the  page  to  designate  this  airport  as  the nearest  airport.    However,  if  flight  is  continued  along the flight plan with this page selected, the same airport will be displayed and its position in the nearest airports list will change from NR  1 to NR 2, NR  3 … NR 9 until it won’t be on the nearest airport list.  The reason for this is that in the event of an actual emergency, once an   airport   has   been   selected,   the   list   won’t   update while  maneuvering  or  looking  up  data  on  other  airport pages.      To   have   the   NR 1  continuously  change  to reflect the nearest airport, perform the following steps. 1.   Display     the     nearest     airport     page     by pressing    the    MSG    button    followed    by pressing the ENT button. 2.   Press the right CRSR button. 3.   Rotate  the  right  outer  knob  clockwise  to position the cursor over NR 1.  As long as the cursor is left in this position, this page will  update  so  that  the  nearest  airport  is always shown as the flight progresses. c.   Selecting Waypoints by Name or City.  For VOR's and NDB's, the navaid name may be used.  For airports,  the  airport  name  on  the  APT  1  page  or  the city name on the APT 2 page may be used. 1.   Turn  the  right  outer  knob  to  display  the VOR, NDB, or airport type waypoint.  For the   airport   type   waypoint,   use   the   right inner   knob   to   select   APT 1,   for   airport name,   or   APT 2,   for   airport   location,  as appropriate. 2.   Press the right  CRSR button.  Make sure the right inner button is pushed to the "in" position. 3.   Rotate the right outer knob clockwise until the cursor is over the first character in the VOR  name,  NDB  name,  airport  name,  or airport city name. 4.   Turn  the  right  inner  knob  to  display  the first character. 5.   Turn    the    right    outer    knob    one    step clockwise   and   then   use   the   right   inner knob to enter the second character. 6.   Use   the   right   outer   and   inner   knob   as before to select the remaining characters. 7.   Press the right CRSR button to turn off the cursor function. (1)   Instead     of     an     entire     name,     a     few characters  may  be  entered  and  then  the  waypoints that begin with those characters may be scanned. 1.     Turn  the  right  outer  knob  to  display the VOR, NDB, or airport type waypoint. For the airport type waypoint,  use  the  right  inner  knob  to select APT 1 or APT 2 as appropriate.
