🔍 Key Concepts

• Electronic Plotting Aid (EPA) operation and limitations • Typical manual radar plotting intervals used for collision avoidance (RML, maneuvering board, etc.) • Why EPA needs frequent position updates to maintain a reliable target vector

💭 Think About

• Think about how quickly a target’s relative motion can change and how often you normally update manual radar plots in close-quarters situations. • Consider what would happen to the accuracy of CPA/TCPA if you wait too long between manual plots on an EPA. • Compare the answer choices to the usual time intervals taught for manual radar plotting of targets on paper or plotting sheets.

✅ Before You Answer

• Check which interval is commonly used as the maximum safe gap between manual plots before the system considers the data too old to trust. • Eliminate any choice that seems too long to be safe for collision avoidance in a busy traffic situation. • Compare the options with the standard plotting intervals you learned in radar observer or ARPA/EPA training.
