Flying the Vectors Approach
With “vectors to fi nal” selected, the CDI
needle will remain off center until you’re
established on the fi nal approach course.
With the approach activated, the map page
will display an extension of the fi nal ap-
proach course in magenta (remember, ma-
genta is used to depict the active leg of the
fl ight 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-fi nal). In this example, we’ll
assume ATC vectors result in a rectangular
course to intercept fi nal, as follows:
1. Within 30 nautical miles of KTOP, the GNS 430
will switch from enroute mode to terminal mode
and the CDI scale will transition from 5.0 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
GNS 430 to guide you to the final approach
course. (See page 79.)
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 con-
verge with the final approach course the needle moves toward the center. (In the illustration at left, the
needle has not yet returned to the on-screen CDI, since your current position is still 1.7 nm right of the
final approach course.)
