NOTE: Following sequence of WPT, the FMS turns to capture the final
approach course. The FMS is not flying a defined ground track during
this maneuver. Depending on speed and teardrop geometry, the FMS
can roll wings level on a 45_ intercept to the final approach course.
Typically, the aircraft banks until the final approach course is captured.
