TM 1-1510-218-10 3A-41 6.   Vary the TILT control manually between  0  and  up  15°  and  observe that  close  in  “ground  clutter”  appears at   lower   settings   and   that   any   local rain appears at higher settings. 7.   Repeat the manual tilt adjustment, this time   between   the   0   and   down   15° positions. 8.   Function switch   –  Return  to   TST  or SBY before taxiing. 9.   Function switch, before or after takeoff – ON and operate as required. 3A-30.  RADAR GRAPHICS. a.   Description.    The  KGR-358  radar  graphics unit interfaces with the weather radar system (RDR 2000),   and   receives   navigation  data  from  the flight management system, KLN 90B.  Refer to Figure 3A-24.    The  unit  can  display  NAV  1  or  NAV  2  or  both in a weather overlay, or as navigation information only display.  In addition, NAV information can be viewed in a   360°   (circle)   display  with  weather  in  the  top  90° sector.    Two  checklist  modes  are  also  provided  for complete checklist capability when utilizing the pocket terminal. With the KGR-358 in any of the NAV modes, the radar screen will display a normal weather picture plus the  location  of  the  waypoints  listed  in  the  active  flight plan.    Data  referenced  to  NAV  1  is  displayed  in  the lower left portion of the radar display.  Data referenced to  NAV  2  will  display  in  the  lower  right  portion  of  the display.    Included  in  the  data  are  the  active  waypoint name,  the  selected  course  bearing,  and  the  aircraft position    (radial    to,    and    distance)    from    the    active navigation fix.  Aircraft magnetic heading is displayed in the upper left section of the radar display. A  line  representing  the  course  selected  by  the flight    management    system    is    drawn    through    the corresponding    active    waypoint.        Selected    course bearing  for  each  NAV  system  is  displayed  with  NAV data  on  each  side  of  the  screen.    A  waypoint  line  will also     be     displayed     connecting     the     waypoints     in numerical  sequence.    An  R  on  the  left  side  of  the screen  indicates  all  visible  NAV  aids  selected  by  the flight management system will be displayed.  The level of  NAV  aids  displayed  is  indicated  by  one,  two,  or three dots on the left side of the R. A joystick control is provided to move a waypoint to any position on the screen.  The coordinates for this new   waypoint   will   appear   in   the   lower   left   or   right corner    depending    upon    which    NAV    is    selected replacing   the   active   waypoint   data.      If   both   NAV systems   are   selected,   the   new   coordinates   will   be displayed    corresponding    to    NAV    1,    and    may    be switched  to  NAV  2.    Pressing  the  check  button  will cause  the  data  to  transfer  to  the  flight  management system and be fixed as a position on the earth.  Once the   data    is    transferred    to    the    flight    management system, the pilot may enter it, as he desires. 1.  Mode Selector Knob 2.  Left / Right Cursor Buttons 3.  Joystick 4.  CANCEL Button 5.  PAGE Button 6.  Up / Down Cursor Button 7.  Input Jack 8.  Checklist Button 9.  Index Button Figure 3A-24.  Radar Graphics A track line enables a quick determination of how many   degrees   deviation   left   or   right   of   a   present heading is needed to provide for a clear path through weather or to a new fix.  The number of degrees and a L  or  R  is  shown  in  the  upper  left  corner  replacing the magnetic heading when track mode is in operation.
