Nonstop flight route between Challis, Idaho, United States and Sisimiut, Greenland:

About this route:

A direct, nonstop flight between Challis Airport (CHL), Challis, Idaho, United States and Sisimiut Airport (JHS), Sisimiut, Greenland would travel a Great Circle distance of 2,659 miles (or 4,280 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 Challis Airport and Sisimiut 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 Challis Airport and Sisimiut Airport. You'll see that it will travel the same route of the red line on this map!

• Because of Challis Airport's high elevation of 5,072 feet, planes must typically fly at a faster airspeed in order to takeoff or land at CHL. Combined with a high temperature, this could make CHL a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• In addition to being known as "Challis Airport", another name for CHL is "LLJ".
• The closest airport to Challis Airport (CHL) is Lemhi County Airport (SMN), which is located 45 miles (72 kilometers) NNE of CHL.
