• Dangerous targets (ones causing Range or Approach Time alarm), colored red
• Active targets (within Active range)
• All other targets
AIS Report lists the following parameters of AIS targets in a table: Vessel name or MMSI id, Target
Speed (SOG), Target Course (COG), Range for Closest Approach to a Target (CPA), Time for Closest
Approach to a Target (TCPA). The following actions are available via soft-keys:
Sort AIS Targets can be sorted by Vessel Name, MMSI id, Radio Call Sign, SOG, COG, CPA
and TCPA in Ascending or Descending order; default is: CPA, Ascending; current sort
mode is displayed by triangle in corresponding column title.
Locate (also ENTER key) centers the map on current AIS target, puts cursor over it so AIS Quick

A.1.8 AIS Tracks
A very useful feature of AIS, is the ability to store and display exactly where certain AIS Target has
been. This feature, referred to as AIS Tracking, can provide invaluable visual information about past
route of AIS target.
NOTE
It is important to separate Own Track (a line connecting past GPS positions of own vessel / boat) and
AIS Track – a line connecting positions of certain AIS target.
A.1.9 AIS Track List window
AIS Track List is full-screen window similar to Track List window; but AIS Track List contains tracks for
AIS Targets selected by the user – and not track data for own vessel. Here in the table user can see a
list of 10 most recent AIS Targets, for which user enabled Track function: number of track, AIS vessel
name or MMSI callsign (if name was not available), track type (default: recorded by distance, step is
0,05 Nm) and color (default: color of AIS Target, refer to par. 3.7.1a).
