z The basic target data display for a TT consists of the following information:
• TT no. Target numbering starts from "1". When a target is erased the number will
not be reused until the power is re-set or more than 100 targets are acquired.
• Bearing (BRG) and distance (RNG) of the target from own ship
• True speed over the ground (SOG) and true course over the ground (COG) of
the target
• CPA and TCPA. A negative TCPA value means that you have already passed
the closest point and the TT is going away from own ship.
• Bow Closest Range (BCR) and Bow Closest Time (BCT)
