What is NOT an advantage of the rhumb line track over a great circle track?

A Does not require constant course changes
B Negligible increase in distance on east-west courses near the equator
C Easily plotted on a Mercator chart
D Plots as a straight line on Lambert conformal charts
AI Explanation

The correct answer is D) Plots as a straight line on Lambert conformal charts. The rhumb line track, which maintains a constant compass bearing, does not plot as a straight line on Lambert conformal charts, unlike the great circle track. This is because Lambert conformal charts are designed to preserve shapes and angles, but not distances, making rhumb lines appear curved on this projection. In contrast, great circle tracks, which represent the shortest distance between two points, will plot as straight lines on Lambert conformal charts. The other answer choices are advantages of the rhumb line track over the great circle track, such as not requiring constant course changes, having a negligible increase in distance on east-west courses near the equator, and being easily plotted on a Mercator chart.
