4.2. OPERATING FROM THE ACTIVE FLIGHT PLAN
4.2.1. GENERAL PROCEDURES
Everything you have learned in this Pilot’s Guide thus far is
applicable to using the KLN 89(B) for flight plan operation. The
following rules and considerations apply for flight plan operation while
the KLN 89(B) is in the Leg mode:
• Always verify that you are viewing the active flight plan page
(FPL 0) and not one of the other numbered flight plan pages.
• The active leg of the flight plan is designated with a symbol.
A leg is defined as the course line between a pair of waypoint (a
“from” waypoint and a “to” waypoint). The head of the arrow is
positioned to the left of and points to the active “to” waypoint. In
figure 4-28, SLC (Salt Lake City VOR) is the “to” waypoint. The
tail of the symbol is positioned to the left of the “from” way-
point. KPVU (Provo Municipal) is the “from” waypoint in figure
4-28. The symbol is not dis-
played unless the KLN 89(B) is
actually receiving GPS signals
suitable for navigation. (Note: If
the unit is in the take-home mode,
it has been “tricked” into thinking
it is receiving signals and there-
fore the symbol can be
displayed). Also, the symbol
will not be displayed if Direct To
navigation is occurring and the
Direct To waypoint is not in FPL
0. If in doubt as to whether or not
Direct To operation is occurring,
view the NAV 1 page. If the top
line shows the symbol (figure
4-29) instead of a “from” waypoint
(figure 4-30), then Direct To navi-
gation is occurring. If it is desired
