Line 33: Chartplotters may be programmable, and can be set to generate audible and visual alarms for conditions such as a potential collision, deviating significantly from the planned course, etc. == Related ~~Application~~Applications== The principal function of a classic chartplotter is assisting a human pilot to plot and follow a course. Safety-related [[Automatic Identification System\|Automatic identification systems (AIS)]], required on all passenger vessels and vessels of 300 tons and over, also assist in piloting, and can display on the chartplotter. AIS have collision avoidance, and avoidance of known hazards such as reefs, as their primary function. AIS depend on cooperative data communications among ships. [[Vessel Traffic Service\|Vessel traffic services (VTS)]] go even farther as safety systems, being analogous to the proactive function of air traffic control systems. VTS assist vessel traffic control in routing vessels in busy waters. Other vessel-based safety collision avoidance functions are [[Automatic Radar Plotting Aid\| Automatic Radar Plotting Aids (ARPA)]], usually a component of the radar system or an accessory to it, and coupled with the radar system input to the chartplotter. ==External links==
