CHAPTER 6 MAP OPERATIONS
Overview
MAP operations allow you to display navigation information in the
form of a “moving map” directly on the SN3500 display. You have
extensive control over what kinds of navigation information are
displayed on the map:
•
Airports
and
Runways
•
Controlled and Special Use Airspace
•
VORs
•
NDBs
•
Intersections
•
GPS Flight Plans and Approaches
Within each of these classes of map objects you may fine-tune
exactly which items you want displayed. For example, you may
choose to exclude military or private airports, or those with unpaved
runways or runways shorter than a particular length. Similarly, you
may elect not to display terminal VORs or low-powered NDBs, or to
display Class B airspace and Restricted Areas but exclude Class C
airspace and MOAs. As you will see, the SN3500 offers great
flexibility in how you configure your moving map display.
Finally, you may store up to four different map configurations, and
then quickly switch from one to another as appropriate to your
phase of flight. For instance, when cruising at FL180 or higher, you
might want to display only high-altitude VORs, Special Use Airspace
and airports with paved runways of 6,000 feet or longer. The
SN3500 allows you to save such a map configuration in one of four
map memories and then recall it as needed.
All the airports, navaids and intersections on the moving map,
except for the GPS/FMS flight plan waypoints, come from the
internal database of the SN3500 and are color-coded cyan.
Controlled and Special Use Airspace also comes from the SN3500’s
internal database and are color-coded according to its type (Class B
and Class C in green, MOAs in purple, Restricted and Warning
Areas in yellow, and Prohibited Areas in red.) The GPS/FMS flight

plan waypoints and course line come from the database in the
GPS/FMS and are color-coded magenta or white.
Note: The SN3500 requires a connection to a GPS/FMS receiver in
order to display the moving map. The map display, including the
flight plan from the GPS1 receiver, will also be shown when NAV1
or NAV2 is selected as the primary NAV source.
Internal Database
Non-flight plan data including airspace is referred to as the “internal
database” and is stored in the SN3500’s internal memory. The
internal database can be periodically updated from a Windows-
based PC. The expiration date of the internal database is shown
during the power on sequence. Database updates are available
directly from Sandel Avionics, and may be purchased at
www.sandel.com
by your dealer. As this database is for
supplemental use only and not intended for primary navigation,
there is no requirement to update it.
Map Controls and Displays
Information associated with control of the map is displayed as
follows:
•
The map status bar is shown just to the right of the MAP
button and shows icons for the currently enabled map
items.
•
The map memory location currently being displayed is
shown at the top of the map status bar as “1”, “2”, “3”, “4” or
“S”.
