Nonstop flight route between Port Protection, Alaska, United States and Xining, Qinghai, China:

About this route:

A direct, nonstop flight between Port Protection Seaplane Base (PPV), Port Protection, Alaska, United States and Xining Caojiabao Airport (XNN), Xining, Qinghai, China would travel a Great Circle distance of 5,243 miles (or 8,437 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 Protection Seaplane Base and Xining Caojiabao 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 Protection Seaplane Base and Xining Caojiabao Airport. You'll see that it will travel the same route of the red line on this map!

• Because of Port Protection Seaplane Base's relatively low elevation of 0 feet, planes can take off or land at Port Protection 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.
• Port Protection Seaplane Base (PPV) currently has only 1 runway.
• The furthest airport from Port Protection Seaplane Base (PPV) is Port Alfred Airport (AFD), which is located 10,611 miles (17,077 kilometers) away in Port Alfred, South Africa.
• The closest airport to Port Protection Seaplane Base (PPV) is Point Baker Seaplane Base (KPB), which is located only 2 miles (3 kilometers) NNW of PPV.
