(4) Direct-To
Impromptu
Waypoints.
Impromptu waypoints may be inserted into the flight
plan interrupting execution of the current flight plan
leg. The impromptu point may be any valid waypoint
format. Refer to Figure 3B -42 and Table 3B-33 and
Figure 3B-43 and Table 3B-34 for an illustration of the
two methods of executing Direct-To operations to
impromptu waypoints. When performing a Direct-To
the scratchpad waypoint, the active waypoint will be
pushed
one
waypoint
into
the
future
and
the
scratchpad
waypoint
becomes
the
new
active
waypoint. When the MAP is the active waypoint,
executing a Direct-To the scratchpad waypoint will
move the MAP into history (not future), allowing
departure
into
a
missed
approach
procedure.
Waypoint insertion between the FAF and the MAP is
prohibited, even when the FAF is in history.
