TM 1-1510-225-10 3D-35 ² ² ² WPT   1 WPT  2 WPT  3 Figure 3D-43.  Turn Anticipation (2)   To use the turn anticipation feature, start the turn transitioning to the next leg in the flight plan at the  very  beginning  of  turn  anticipation.    This  occurs when  the  external  waypoint  alert  annunciator  or  the active  waypoint  identifier  on  the  Super  NAV  5  page stops flashing and goes on steady.  The KLN 90B will generate a message on the message page for the new desired  track  to  select  on  the  EHSI:  ADJ  NAV  IND CRS   TO   123^o.    A  message  will  not  be  given  if  the change in desired track is less than 5 or the KLN 90B is interfaced with an EHSI having a course pointer that is automatically slewed to the correct desired track. (3)   The desired track displayed on the NAV 3 page  also  changes  to  the  value  of  the  next  leg  at  the beginning    of    turn    anticipation.        Turn    anticipation becomes  inactive  when  transition  to  the  next  leg  has been made. (4)   The   KLN   90B   can   read   the   selected course  set  on  the  external  EHSI.    The  KLN  90B  will flash the value of the desired track on both the NAV 3 and  the  Super  NAV  5  pages  when  the  desired  track and the selected course differ by more than 10°.  Set the  selected  course  to  match  the  desired  track.   This will   ensure   that   the   orientation   is   always   pictorially correct. (5)   If    desired,    turn    anticipation    may    be disabled, or enabled, on the SET 6 page. i.    Viewing the Waypoint Pages for the Active Flight Plan Waypoints.   The waypoint pages for each of   the   waypoints   in   the   active   flight   plan   may   be displayed by selecting  the  Active  Waypoint  page  with the right outer knob.  Refer to Figure 3D-44.  When the ACT page is first selected, the waypoint page for the active   waypoint   will   be   displayed.      The   sequence number     of     the     waypoint     in     the     flight     plan     is annunciated with a number to the left of the identifier.   An arrow to the left of the waypoint number designates the  active  waypoint.    The  letter  to  the  far  right  of  the identifier designates the type of waypoint:  A – airport, V – VOR, N  – NDB, I  – intersection, S – supplemental, or T  – terminal.  For VOR’s having DME capability, the letter  D  is  displayed  between  the  VOR  identifier  and the V.

When  DIRECT  TO  operation  to  a  waypoint  on the   active   flight   plan   is   selected,   the   system   will provide navigation to the waypoint and then automatically  resume  navigation  along  the  flight  plan when the DIRECT TO  waypoint is reached.   Waypoints that exist prior to the DIRECT TO  waypoint in  the  active  flight  plan  are  bypassed.    Navigation  on the active flight plan will not be resumed if the  DIRECT TO operation is to a waypoint that is not in the active flight plan. (1)   Any of the methods previously described for  initiating  direct  to  operation  may  be  used.    The following procedure is the easiest for this application. 1.   Select the FPL 0 page on the left side. 2.   Press  the  left  CRSR  button  and  then use the left outer knob to position the cursor    over    the    desired    waypoint.   Refer to Figure 3D-45. 3.   Press the   D      button.    The  waypoint page for the selected waypoint will be displayed  on  the  right  side.    Refer  to Figure 3D-46.
