Selecting an Approach
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 495 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 495 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 495 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.
A turn is 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.
To cancel the vectors and/or approach:
1. Press
Direct To
, and press
MENU
on the Go To Page.
OR
From the Active Go To (or Active Route) Page, press
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.
