The Great Routes are the routes that take the aircraft over the northern (or southern) hemisphere and sometimes close to the North Pole. This routes are flown on long-distance flights from USA to Japan or USA to Europe. The reason these flights are flown is that it is shorter. Also, the Earth is not a perfect sphere and it is a shorter distance to fly these Northern routes. Try this. Look at a flat map and layout a direct route from Chicago to Paris, France. Then use a globe and a string and layout a route that is the shortest (using the least amount of string). See how much the northern route is shorter than the "direct route".

Do pilots fly a certain path to get to a place quicker?

Yes, they fly the great circle route.


An imaginary line that follows the curve of the earth and is the shortest route for pilots?

The imaginary line that follows the curve of the Earth and is the shortest route for pilots is called a great circle route. This route is the most efficient way to travel between two points on the Earth's surface, as it represents the shortest path over the Earth's surface, given its spherical shape. Pilots often use great circle routes to save time and fuel during long-distance flights.


What does the great-circle route represent?

It is the shortest distance between two points on a sphere, where the sphere in question is the earth. Particularly long airline flights follow great circle routes.


Compare a straight route with a great circle route?

A straight route is the path taken in a straight line while the shortest distance between two points on a circle is known as the great circle route. However, while travelling the great circle around the globe, the path ahead will look like the straight route.


What type of map projection is used by airline pilots?

The type of map projection used by pilots is called a Polar Projection. It shows the Earth from one of the two poles, which helps show what is known as The Great Circle Route. This states that if you live on a rounded object such as the Earth, you travel on a curved line. This makes a Polar Projection the best choice and most commonly used map projection used by pilots.
