VTS targets (targets derived by means other than AIS)

Introduction/Additional information: 

This IFM should be used to transmit VTS targets. This message should be variable in length, based on the amount of VTS targets. The maximum of VTS targets transmitted in one IFM 16 should be seven (7). Because of the resulting effects of VDL channel loading, the transmission of IFM 16 should be no more than necessary to provide the necessary level of safety.

A VTS target should only be used when the position of the target is known. However, the target identity and/or course and/or time stamp and/or speed over ground may be unknown.
