Flying the Vectors Approach
With“Vectors-To-Final”(VTF)selected,theCDI
needle remains off center until you’re established on
the final approach course. With the approach acti-
vated, the Map Page displays an extension of the final
approach course in magenta (remember, magenta is
used to depict the active leg of the flight plan) and
“VTF”appearsaspartoftheactivelegontheDefault
NAVPage(asareminderthattheapproachwas
activated with vectors-to-final). In this example, we’ll
assume ATC vectors result in a rectangular course to
intercept final, as follows:
DO NOT USE FOR
NAVIGATION
1. When VTF is activated, the 500W-series unit
switches to approach mode and course guid-
ance is given along the final approach course.
CDI full-scale deflection is as shown in Appen-
dix C.
2. The unit suspends automatic waypoint
sequencing in this case, because VTF was
activated while on the “From” side of the Final
Approach Fix.
If the approach is loaded, but not yet
activated, press PROC and select “Activate
Vectors-To-Final?”.
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 following illustration, the needle has
returned to the on-screen CDI and your current
position 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.
