Figure 3B-47. Automatic Cancellation of Parallel Course Offsets
(3) Waypoint Transition with Parallel Offsets.
The parallel offset flight plan may result in severe
geometry at waypoints with large course changes. To
resolve this condition the offset pseudo-waypoint is
never displaced along the inbound leg track by more
than two times the width of the offset. Figure 3B-48
shows an offset definition where the along track shift of
the pseudo - waypoint is less than two times the offset
width, resulting in a continuous offset flight plan.
If a leg course change is greater than 127, a
course discontinuity is created. Upon reaching the
switch point the new offset course for the next leg
becomes active. Figure 3B -49 shows examples with
the offset on both the inside and outside of the
required turn.
