Question 110Navigation General
70% to passAll straight lines represent great circle tracks on a chart based on a(n) _______________.
A
Mercator projection
B
orthographic projection
C
polyconic projection
D
gnomonic projection
AI Explanation
The correct answer is D) gnomonic projection. On a gnomonic projection, all straight lines represent great circle tracks, which are the shortest distance between two points on the Earth's surface. This is because the gnomonic projection is centered on a point, and great circles appear as straight lines when viewed from that central point. The other projection options are incorrect because they do not have this property - Mercator, orthographic, and polyconic projections all distort the representation of great circles, which appear as curved lines on those chart types.
