What are the two benefits of using the great circle route?
1)All meridians of longitude are great circles. Great circle are of importance to navigation and aviation. 2)The shortest route between any two places is along the arc of the great circle which passes through them.
What is the most significant use of great circle?
navigation The most famous use of great circles in geography is for navigation because they represent the shortest distance between two points on a sphere. Due to the earth's rotation, sailors and pilots using great circle routes must constantly adjust their route as the heading changes over long distances.
Why are great circles used for air and sea travel routes?
Planes travel along the shortest route in 3-dimensional space. This route is called a geodesic or great circle. While map projections distort these routes confusing passengers, the great circle path is the shortest path between two far locations. This is why pilots fly polar routes saving time and distance.
How do you navigate a great circle route?

In what circumstances does great circle provide the most convenient route?
Great circle routes, which require constantly changing headings, are most useful beyond the equatorial regions and for distances greater than several hundred miles. Long-distance air traffic uses great circle routes routinely, saving time and fuel. Navigational radio signals also follow great circle paths.
What is great circle sailing in navigation?
noun Navigation. sailing between two points more or less according to an arc of a great circle, in practice almost always using a series of rhumb lines of different bearings to approximate the arc, whose own bearing changes constantly unless it coincides with a meridian or the equator.
What is great circle track in navigation?
great circle route, the shortest course between two points on the surface of a sphere. It lies in a plane that intersects the sphere's centre and was known by mathematicians before the time of Columbus.
What are the advantage and disadvantage of the great circle sailing?
The advantage of a great circle is obvious, the shorter distance. The disadvantages, depending on latitude, could be quite a few. Colder weather, stronger winds, higher seas and perhaps even icebergs.
What is the advantage of a great circle?
Great circles are also useful in planning routes. The shortest path between two points on the surface of a sphere is always a segment of a great circle. Plotting great circles comes in very handy for airplane pilots trying to fly the shortest distance between two points.
What is the advantage of great circle sailing?
The advantage of a great circle is obvious, the shorter distance. The disadvantages, depending on latitude, could be quite a few. Colder weather, stronger winds, higher seas and perhaps even icebergs.
Why great circles are the shortest route?
(iii) Great Circles are the shortest routes between two places as we can connect any two places on the earth's surface by the curvature line of the great circle. And this curvature is the smallest possible route between those two places, because this curvature directly connects those places or points.
