Nonstop flight route between Patuxent River, Maryland, United States and Songpan County, Sichuan, China:

About this route:

A direct, nonstop flight between Naval Air Station Patuxent River (NHK), Patuxent River, Maryland, United States and Jiuzhai Huanglong Airport (JZH), Songpan County, Sichuan, China would travel a Great Circle distance of 7,521 miles (or 12,105 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 Naval Air Station Patuxent River and Jiuzhai Huanglong 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 Naval Air Station Patuxent River and Jiuzhai Huanglong Airport. You'll see that it will travel the same route of the red line on this map!

• Because of Naval Air Station Patuxent River's relatively low elevation of 39 feet, planes can take off or land at Naval Air Station Patuxent River 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 Naval Air Station Patuxent River (NHK) is St. Mary's County Regional Airport (LTW), which is located only 8 miles (12 kilometers) WNW of NHK.
• The furthest airport from Naval Air Station Patuxent River (NHK) is Margaret River Airport (MGV), which is located 11,728 miles (18,874 kilometers) away in Margaret River, Western Australia, Australia.
