Nonstop flight route between College Park, Maryland, United States and Challis, Idaho, United States:

About this route:

A direct, nonstop flight between College Park Airport (CGS), College Park, Maryland, United States and Challis Airport (CHL), Challis, Idaho, United States would travel a Great Circle distance of 1,943 miles (or 3,126 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 College Park Airport and Challis Airport, the route shown on this map most likely still appears to be a straight line.

Facts about College Park Airport (CGS):

• Because of College Park Airport's relatively low elevation of 48 feet, planes can take off or land at College Park 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.
