Page 31: Selecting An Approach
Selecting an Approach CAUTION: The approaches provided in the Jeppesen database are for monitoring purposes only. The GPSMAP 496 is not an IFR-approved instrument and should not be used as a primary source of navigation guidance in instrument conditions. When you select an approach, it replaces the destination airport with the sequence of waypoints for the selected approach.
Page 32: 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 496 creates an extension of the ﬁnal course, beyond the ﬁnal approach waypoint in the database (ﬁnal approach ﬁx [FAF]).
