Vectors-To-Final Approach
2. The unit suspends automatic waypoint
sequencing in this case, because VTF was
activated while on the “From” side of the Final
Approach Fix.
3. ATC instructs you to turn left to a heading
of 025°. This places you parallel to the final
approach course in the opposite direction. CDI
needle deflection is to the left.
4. ATC instructs you to turn right to a heading of
115°.
5. ATC instructs you to turn right to a heading of
175° to intercept the final approach course. As
you converge with the final approach course
the needle moves toward the center. (In the
illustration below, the needle has returned
to the on-screen CDI and your current posi-
tion is less than 0.5 NM right of the final
approach course.) Once the aircraft is within
the approach course and the CDI is active,
automatic waypoint sequencing resumes and
SUSP is removed.
6. As the CDI needle centers, make any remaining
course corrections to establish yourself on the
final approach course.

NAVIGATION
7. As you approach the FAF, a waypoint alert in
the lower right corner (“Next DTK 214° in xx
sec”) appears. Make any course adjustments
necessary for the final course segment (FAF to
MAP). After the FAF, VLOC guidance should be
used for this approach. LNAV remains annunci-
ated to indicate on-screen CDI sensitivity.
