Vectors-To-Final Approach
Flying the Vectors Approach
With “vectors to final” selected, the CDI needle
will remain off center until you’re established on the
final approach course. With the approach activated,
the
map page will display an extension of the final
approach course in magenta (remember, magenta is
used to depict the active leg of the flight plan) and
“VTF” will appear as part of the active leg on the
default NAV page (as a reminder that the approach was
activated with vectors-to-final). In this example, we’ll
assume ATC vectors result in a rectangular course to
intercept final, as follows:

1. When VTF is activated, the 500W-series unit
switches from en route mode to terminal mode
and the CDI scale transitions from 2.0 to 1.0
nautical miles, full scale deflection.
2. If you haven’t already done so, activate the
approach (with vectors-to-final). This allows
the 400W-series unit to guide you to the final
approach course.
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 not
yet returned to the on-screen CDI, since your
current position is still 1.9 NM right of the final
approach course.)
