🔍 Key Concepts

• Plan Position Indicator (PPI) displays your ship in the center with bearings shown around the scope • The sweep line represents the rotating radar beam showing which direction the antenna is pointing at any instant • A heading flash is tied to the ship’s own heading, not to targets or depth

💭 Think About

• On a PPI, what does the fixed reference direction need to show so the operator can align contacts with the ship’s bow? • Does the heading flash change location with every rotation of the antenna, or does it stay at a specific bearing relative to the ship? • Which answer choices talk about external conditions (targets, depth, antenna direction) versus a constant reference for the operator?

✅ Before You Answer

• Identify which option describes a constant reference line on the screen, not something that comes and goes with conditions • Eliminate choices that depend on targets appearing or disappearing • Eliminate choices that depend on water depth or on whether the antenna is pointed forward or aft
