Question 430Navigation General70% to pass
On a gnomonic chart, a great circle track between Los Angeles and Brisbane will appear as a _______________.
AI Explanation
The correct answer is A) straight line.
On a gnomonic chart projection, which is a type of map projection centered on a point, great circle tracks appear as straight lines. This is because a great circle is the shortest distance between two points on the surface of a sphere, and on a gnomonic chart, great circles are represented as straight lines.
The other answer choices are incorrect because: B) a loxodromic curve is a rhumb line, which appears as a curved line on any map projection; C) a curved line concave to the equator would not be the representation of a great circle on a gnomonic chart; and D) a spiral approaching the poles is not the correct representation of a great circle on a gnomonic chart.
