Query Options
The Chart Query Options control allows you to
set the following query options:

Filter - search by geometry type (points,
lines, areas, and/or 3D and cluster
points)

Area Size - search area as a factor of
scale (small, medium, large)
To include the basic geometry types in chart
queries tick their check box. At least one check
box must be ticked in order to receive query
results.
The Query Area Size control allows you to select from three different sizes
of query region, all three of which are based on the current selected scale
ratio of the chart display.
The default values for query area size are as follows:

Small = 10% of the scale ratio

Medium = 20% of the scale ratio

Large = 30% of the scale ratio
Chart Query on AIO Data
When the AIO checkbox is ticked in Chart Settings Symbology, AIO objects
that are associated with one or more AVCS ENC chart in the current
display will be rendered when accessed from Chart Query. Chart filtering
modes will not affect the display of AIO objects.
AIO data is provided as temporary notices, preliminary notices or No
Information objects. Details of AIO data may be displayed in either a
secondary window, either as text or pictorial representation.
Displayed AIO data is listed in the Update tab of Chart Legend, providing
detail about the AIO objects that were added and removed during each
weekly update.
