🔍 Key Concepts

• Lambert conformal conic projection characteristics, especially how it represents rhumb lines vs great circles • How distance and course angles are normally measured on a Lambert conformal chart • The meaning of standard parallels on conic projections

💭 Think About

• Ask yourself: On a Lambert conformal chart, what kind of line appears as a straight line—rhumb line (loxodrome) or great circle? • Think about where on the chart you normally take the course angle for a long track: at the midpoint of latitude, midpoint of longitude, or somewhere else? • Consider whether standard parallels are limits where the chart becomes unusable, or simply where scale is most accurate.

✅ Before You Answer

• Verify how straight lines on a Lambert conformal chart relate to rhumb lines vs great circles • Confirm where scale is true on a Lambert conformal projection (at which latitudes) • Check standard practice for measuring distance and course on Lambert conformal charts used in high latitudes

When navigating in high latitudes and using a chart based on a Lambert conformal projection, which is TRUE?

The distance cannot be measured directly from the chart

The course angle is measured at the mid-longitude of the track line

A straight line drawn on the chart approximates a great circle

The chart should not be used outside of the standard parallels
