Press the Nav button, select Map . In the Map menu
select Filter . In the filter menu you can scroll to the
desired navaid with the Up and Down arrows and
change the settings with the Left and Right arrows. When your
selections are complete you can back out of each section of menus
by pressing the Nav button.
The
Range setting in the menu allows you to set the distance
ahead of your aircraft that you want this type of navaid to be
displayed. The Zoom setting is the range, in miles, as shown in
the upper right hand corner of the moving map at which all of the
Navaids will disappear.
You can set the
Distance filter for public and private airports.
Airports do not have a zoom setting, but automatically determine
if they should be displayed at a given zoom range based on the
size of the facility.
The
Minimum Runway filter sets the minimum runway length
needed for an airport to display on the map or in airport lists.
Example - Setting VOR Distance to 200 miles and VOR Zoom to 500
miles would mean that you can see VOR’s up 200 miles ahead of you,
but if you increased the range of the compass ring out to 500 miles all
the VOR’s would disappear
