Labels
The labels criterion specifies whether items are displayed on the
map with an associated label. The label generally contains the
identifier of the item being displayed.
Range
The range criterion specifies the maximum map range at which
items in the layer will be displayed. At or below that range, items
will be displayed. Above that range, they will not.
Detail
The detail criterion specifies the map detail level at or above
which items in the layer will be displayed. The symbol displayed
corresponds to the detail level symbol shown on the Nav LSK of
the Map page. If the selected nav detail level is at the same level
specified in the condition or higher (i.e. more filled in), then the
item will be displayed.
Altitude
The altitude criterion specifies a related altitude component
defining whether an item in the layer is to be displayed. The
meaning of the altitude criterion varies based on the layer being
processed.
In the case of an airspace layer, the altitude criterion specifies a
number of feet above the airspace ceiling. The airspace will be
displayed when the aircraft is less than the specified number of
feet above the airspace ceiling.
In the case of an obstacle layer, the altitude criterion specifies a
number of feet above the obstacle. An obstacle will be displayed
when the aircraft is less than the specified number of feet above
the obstacle.
In the case of an airway layer, the altitude criterion specifies an
MSL altitude. Victor airways will be shown when the aircraft is
below the specified altitude. Jet airways will be shown when the
aircraft is at or above the specified altitude.
In the case of power lines, the altitude criterion specifies an AGL
altitude. Power lines will be shown when the aircraft is below the
specified AGL altitude.
