GPS 500 Pilot’s Guide and Reference
SECTION 5
PROCEDURES
5-3
Another Procedures Page option allows the pilot to
activate the final course segment of the approach. This
option assumes the pilot will receive vectors to the final
approach x (FAF) and provides guidance to intercept the
nal course, before reaching the FAF.
Activating the approach, with vectors to
final:
1) Press the PROC Key to display the Procedures
Page.
2) Turn the large right knob to highlight ‘Activate
Vector-To-Final?’ (Figure 5-6) and press the
ENT Key.
Figure 5-6 Procedures Page
3) A confirmation window will appear with ‘Yes?’
highlighted, press the ENT Key.
In many cases, it may be easiest to ‘Load’ the full
approach while still some distance away, enroute to the
destination airport. Later, if vectored to final, use the
steps above to select ‘Activate Vector-To-Final’—which
makes the inbound course to the FAF waypoint active.
Otherwise, activate the full approach using the ‘Activate
Approach?’ option.
5.2 NON-PRECISION APPROACH
OPERATIONS
The GPS 500 provides non-precision approach guidance
using its built-in GPS receiver. The GPS receiver can also
be used as a supplemental aid for precision approaches
(and for non-precision localizer-based approaches), but
localizer and glideslope receivers must be used for primary
approach course guidance.
Approaches designed specically for GPS are often
very simple and don’t require overying a VOR or NDB.
Many non-precision approaches have ‘GPS overlays’ to
let the pilot y an existing procedure (VOR, VOR/DME,
NDB, RNAV, etc.) more accurately using GPS.
Many overlay approaches are complex (in comparison
to GPS-only approaches). The GPS 500 displays and
provides guidance through each leg of the approach,
automatically sequencing through each of these legs, up
to the missed approach point (MAP). Approaches may
be own ‘as published’ with the full transition using any
published feeder route or initial approach x (IAF), or
may be flown with a vectors-to-final transition.
NOTE: The following approach examples are
intended for instructional use only and are not
to be used for navigation.
