The ARPA term CPA refers to:

🔍 Key Concepts

• CPA (Closest Point of Approach) in ARPA and radar plotting • How ARPA uses CPA and TCPA to assess collision risk • Difference between a position on your bow and the minimum distance between two vessels

💭 Think About

• Ask yourself what information you really need from ARPA to judge collision risk: is it about angle, processing, or minimum distance between vessels? • Think about what the words in the abbreviation CPA most likely stand for in collision-avoidance context. • Which option describes a value that can be compared to your vessel’s safety distance (e.g., 1 mile, 0.5 mile) rather than a direction or process?

✅ Before You Answer

• Verify which choice clearly describes a distance of minimum approach rather than a bearing or a system function. • Eliminate any option that talks about direction instead of a specific closest distance. • Check that the choice you select could reasonably be shown as a numerical range in miles or cables on an ARPA display.
