Nonstop flight route between Changi, Singapore and Challis, Idaho, United States:

About this route:

A direct, nonstop flight between Singapore Changi Airport (SIN), Changi, Singapore and Challis Airport (CHL), Challis, Idaho, United States would travel a Great Circle distance of 8,493 miles (or 13,668 kilometers).

A Great Circle is the shortest distance between 2 points on a sphere. Because most world maps are flat (but the Earth is round), the route of the shortest distance between 2 points on the Earth will often appear curved when viewed on a flat map, especially for long distances. If you were to simply draw a straight line on a flat map and measure a very long distance, it would likely be much further than if you were to lay a string between those two points on a globe. Because of the large distance between Singapore Changi Airport and Challis Airport, the route shown on this map most likely appears curved because of this reason.

Try it at home! Get a globe and tightly lay a string between Singapore Changi Airport and Challis Airport. You'll see that it will travel the same route of the red line on this map!

• Because of Singapore Changi Airport's relatively low elevation of 22 feet, planes can take off or land at Singapore Changi Airport at a lower air speed than at airports located at a higher elevation. This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
• A new parallel runway 02R/20L was built 1.8 km to the east of 02C/20C, currently used only by Republic of Singapore Air Force aircraft as part of Changi Airbase.
