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, the
needle has returned to the on-screen CDI and your current position is less than 1.0 nm right of the
final approach course.

Flying a Vectored Approach

With "Vectors-To-Final" selected, the CDI needle
remains off center until you're established on the final

approach course. The Map Page displays an extension
of the final approach course in magenta (remember, ma-
genta is used to depict the active leg of the flight plan)
and "VTF" is annunciated in the lower left corner of the
screen (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. Within 30 nautical miles of KTOP, the GNS 480
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 VTF mode
and set the inbound course on the CDI. This allows the
GNS 480 to guide you to the final approach course.
Verify that "VTF" is annunciated.
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.
