scope:

This document specifies the minimum operational and performance requirements, methods of testing and required test results and the effect on extant standards, that are recommended to be complied with for optional equipment conforming to Interim Operational Guidelines not inferior to those adopted by the IMO in SN/Circ.217 (11 July 2001) - Interim guidelines for the presentation and display of AIS target information. The scope is further restricted to requirements for superimposition of selected parts of AIS information on radar systems. All text of this standard, which is identical to that in IMO SN/Circ.217 is printed in italics and the Circular and paragraph numbers are indicated in brackets, for example - (C.217/3.3) The interim guidelines deal with the graphical presentation, alphanumeric information and the display of AIS target data in standalone or integrated navigational aids or systems and are considered as an interim performance guideline. They should be replaced by the appropriate performance standards after experience has been gained. (C.217/2) The fusion of AIS and radar plotting (RP) data and information is not detailed in this guideline as it is only permitted when the functionality meets the requirements of an "Integrated Navigation System", as specified in the relevant IMO Performance standards.
