Rather than stay on a constant heading, pilots must regularly adjust their course to stay on the arc and for this, great circle routes are created. Great circle routes are the lines of a great circle. To make some types of transport faster, great circles step in to help in the form of great circle routes. Thus, great circle routes are routes that make certain ways of transport faster and efficient.
