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!

Facts about Naval Air Station Patuxent River (NHK):

• 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.
• 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.
• In 1937, the Navy's Bureau of Aeronautics sought to consolidate aviation test programs, previously being conducted at several stations, including Dahlgren and Norfolk, the Washington Navy Yard, Naval Air Station Anacostia in Washington, D.C., and the Naval Aircraft Factory in Philadelphia, Pennsylvania.
• Naval Air Station Patuxent River (NHK) has 3 runways.
• A highway extension to the new air station was required by the project—250,000 tons of material were transported by either truck or water routes during a year of construction.
• Research and development at NAS Patuxent River forged ahead in the 1970s.
• 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.
• On 1 April 1976, Patuxent River's air field was named after pioneering aviator VADM Frederick M.
• "Pax River" redirects here.
• In addition to being known as "Naval Air Station Patuxent River", other names for NHK include "Trapnell Field" and "KNHK - FAA: NHK".

• Jiuzhai Huanglong Airport (JZH) currently has only 1 runway.
• Jiuzhai Huanglong Airport, also known as Jiuzhaigou Airport and Jiuhuang Airport, is an airport in Songpan County, Sichuan province, China.
• The closest airport to Jiuzhai Huanglong Airport (JZH) is Mianyang Nanjiao Airport (MIG), which is located 116 miles (187 kilometers) SSE of JZH.
• The furthest airport from Jiuzhai Huanglong Airport (JZH) is Viña del Mar Airport (KNA), which is nearly antipodal to Jiuzhai Huanglong Airport (meaning Jiuzhai Huanglong Airport is almost on the exact opposite side of the Earth from Viña del Mar Airport), and is located 12,156 miles (19,563 kilometers) away in Viña del Mar, Chile.
• Due to the elevation of 3,448 m, some passengers may experience symptoms of altitude sickness.
• Because of Jiuzhai Huanglong Airport's high elevation of 11,312 feet, planes must typically fly at a faster airspeed in order to takeoff or land at JZH. Combined with a high temperature, this could make JZH a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• In addition to being known as "Jiuzhai Huanglong Airport", other names for JZH include "九寨黄龙机场" and "Jiǔzhài Huánglóng Jīchǎng".
