🔍 Key Concepts

• Lambert conformal conic projection properties (how meridians and parallels are shown) • Definition of a bearing (where is the angle actually formed and measured?) • Effect of meridian convergence at high latitudes on how you reference directions

💭 Think About

• On a Lambert conformal chart, ask yourself: where is the point at which the bearing angle actually exists – at the ship, at the object, or somewhere in between? • Think about what a bearing physically is: the angle between the line of sight and which ‘north’ at which location? • In high latitudes, meridians converge. Which meridian best represents the correct directional reference for the navigator taking the bearing?

✅ Before You Answer

• Recall that a bearing is defined at the observer’s position – verify where the observer is in this problem. • On a Lambert chart, meridians are straight but converging lines; confirm which meridian is relevant for the angular reference. • Eliminate any option that suggests an angle is measured at a point other than where the bearing is actually taken.
