The KLN 90B is capable of storing in its memory 25  flight  plans  plus  an  active  flight  plan.    Flight  plans are  numbered  0  through 25.    Each  of  the  flight  plans may  contain  up  to  30  waypoints.    These  waypoints may consist of any combination of published waypoints from the database or user created waypoints. The   active   flight   plan   is   always   FPL   0.      The standard procedure is to create a flight plan in one of the flight plans numbered as 1 through 25.  When one of these numbered flight plans is activated, it becomes FPL  0,  the  active  flight  plan.    If  desired,  a  flight  plan may  be  created  directly  in  the  active  flight  plan.    This avoids creating the flight plan in a numbered flight plan and then having to activate it.  The  disadvantage is the flight plan is not stored and retained for future use.  It can, however, be stored. Modifications   may   be   made   to   FPL   0   without affecting the way it is stored as a numbered flight plan.   Unless  direct  to  operation  is  being  used,  the  active flight plan must contain at least two points. a.   Creating Flight Plans.  1.   Rotate   the   left   outer   knob   to   select   the flight  plan  type  pages.    Refer  to  Figure 3D-35.
