Question

You are planning a voyage by great circle from the mouth of the Delaware River (LAT 38&deg;40'N, LONG 75&deg;00'W) to Lisbon, Portugal. Which statement is TRUE? (Use gnomonic tracking chart WOXZC 5274.)

Accepted Answer

Option A: You will reach the northernmost latitude of the voyage in the vicinity of LONG 42&deg;30'W.. Gnomonic charts represent great circles as straight lines. On a Northern Hemisphere great circle track, the vertex is the highest latitude point. For a Delaware to Lisbon voyage, the track arcs northward, reaching its maximum latitude near 42°30'W, as dictated by the geometry of the Earth's sphere.
