Nonstop flight route between Port Alexander, Alaska, United States and Qingshan, China:

About this route:

A direct, nonstop flight between Port Alexander Seaplane Base (PTD), Port Alexander, Alaska, United States and Xichang Qingshan Airport (XIC), Qingshan, China would travel a Great Circle distance of 5,735 miles (or 9,230 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 Port Alexander Seaplane Base and Xichang Qingshan 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 Port Alexander Seaplane Base and Xichang Qingshan Airport. You'll see that it will travel the same route of the red line on this map!

• The furthest airport from Port Alexander Seaplane Base (PTD) is Port Alfred Airport (AFD), which is located 10,640 miles (17,123 kilometers) away in Port Alfred, South Africa.
• Because of Port Alexander Seaplane Base's relatively low elevation of 0 feet, planes can take off or land at Port Alexander Seaplane Base 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.
• The closest airport to Port Alexander Seaplane Base (PTD) is Point Baker Seaplane Base (KPB), which is located 40 miles (64 kilometers) E of PTD.
• In addition to being known as "Port Alexander Seaplane Base", another name for PTD is "AHP".
