Question 1 of 27070

Which of the following would not be considered an input to the computer of a collision avoidance system?

🔍 Key Concepts

• Basic purpose of a collision avoidance (ARPA/RADAR) computer • Difference between ship motion data (for tracking) and environmental data (for navigation judgment) • Typical sensor inputs: position, course/heading, speed made good/speed through water

💭 Think About

• Ask yourself: What minimum data does the system need to calculate closest point of approach (CPA) and time to CPA (TCPA)? • Which of these choices directly describe own ship’s movement in relation to the earth or water? • Which choice describes a condition of the environment rather than the vessel’s motion or orientation?

✅ Before You Answer

• Identify which options provide position, heading/course, or speed information needed to plot and predict tracks. • Check which option describes wind rather than vessel motion; think about whether the collision-avoidance computer needs that to do CPA/TCPA math. • Recall that collision avoidance systems mainly use navigation sensors (GPS, gyro, log, etc.), not general meteorological sensors.
