Understanding Vectors
The Vectors? option, which appears after you select an approach,
determines how you navigate to the final approach waypoint.
If you select Yes, the GPSMAP 396 creates an extension of the final
course, beyond the final approach waypoint in the database (final
approach fix [FAF]). On the Active Route Page, a Vector to Final
symbol appears beside the first approach waypoint.

Using vectors in the approach
The GPSMAP 396 provides no guidance to the inbound course.
The course deviation needle on the graphic HSI remains off-center
until you are established on this final approach course. The HSI
automatically slews (rotates to show the direction) to the inbound
course. The Map Page shows an extension of the final approach
course using a bold magenta line.
If No is selected for the Vectors? option, the GPSMAP 396 creates
a straight-line course directly to the first waypoint in the approach
(from wherever you are when you initiate the approach). This works
much like any other route with course guidance from point to point
and a turn usually required as you cross each waypoint.
CAUTION:
Steep Turns are not allowed on an IFR (Instrument
Flight Rules) approach. Follow the approach plate or air traffic
control instructions to complete the approach without a steep turn.
If air traffic control clears your approach to an airport, loading the
approach cancels your Direct To and initiates a route to the FAF.
Load the approach only when cleared by air traffic control.
You can cancel an approach and/or vectors several ways:
• Press Direct To
, and press MENU on the Go To Page.
• From the Active Go To (or Active Route) Page, press
MENU.
To cancel the
vectors and/or approach:
1. Press Direct To to show the Go To Page.
OR
Open the Active Route Page. Press MENU to open the
options menu.
2. Highlight Cancel Approach, and press ENTER to cancel
the entire approach. If you enabled Vectors, highlight Cancel
Vectors, and press ENTER to navigate directly to the FAF.
