Electronic Plotting Aid (EPA) has which built in functions?

A Plots at least 20 targets simultaneously
B Trial maneuvering
C Target CPA and time of CPA (TCPA)
D Automatic target tracking
AI Explanation

The correct answer is C) Target CPA and time of CPA (TCPA). Electronic Plotting Aids (EPAs) are required to have the capability to display target course, speed, closest point of approach (CPA), and time to CPA (TCPA). This is a key function of EPAs, as it allows the navigator to assess potential collision risks and take appropriate action. The other options, while potentially useful features, are not mandatory requirements for EPAs based on the applicable regulations and standards.
