Nonstop flight route between Challis, Idaho, United States and Shearwater, Nova Scotia, Canada:

About this route:

A direct, nonstop flight between Challis Airport (CHL), Challis, Idaho, United States and Shearwater Heliport (YAW), Shearwater, Nova Scotia, Canada would travel a Great Circle distance of 2,454 miles (or 3,950 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 relatively short distance between Challis Airport and Shearwater Heliport, the route shown on this map most likely still appears to be a straight line.

• The furthest airport from Challis Airport (CHL) is Pierrefonds Airport (ZSE), which is located 10,728 miles (17,265 kilometers) away in Saint-Pierre, Réunion.

• Because of Shearwater Heliport's relatively low elevation of 144 feet, planes can take off or land at Shearwater Heliport 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.
• Beginning in the 1970s, CFB Shearwater began hosting an Armed Forces Day every fall, typically on the weekend following Labour Day, and included an air show where the long and wide runways at Shearwater hosted some of the largest aircraft in the world, including the U.S.
