Question 1 of 27070

When using a radar in an unstabilized mode, fixes are determined most easily from __________.

🔍 Key Concepts

• unstabilized radar mode vs stabilized mode (what changes with your own ship’s heading) • difference between bearing information and range information on radar • how own-ship turns affect what you can trust for plotting a fix

💭 Think About

• Ask yourself: In an unstabilized display, which quantity stays reliable when your ship changes heading—bearing or range? • Consider which type of radar measurement (bearing vs range) is less affected by small course changes, roll, and yaw. • Think about which kind of measurement is usually preferred for accurate plotting of positions or lines of position from radar.

✅ Before You Answer

• Verify what ‘unstabilized’ means: the display’s zero bearing reference moves with the ship’s head instead of being tied to true or gyro north. • Check which option(s) depend heavily on accurate bearing versus which depend mainly on distance. • Before choosing, ask: If my ship is constantly altering course slightly, which type of radar line of position would remain the most dependable for a fix?
