Nonstop flight route between Buka Island, Papua New Guinea and Changi, Singapore:

About this route:

A direct, nonstop flight between Buka Island Airport (BUA), Buka Island, Papua New Guinea and Singapore Changi Airport (SIN), Changi, Singapore would travel a Great Circle distance of 3,529 miles (or 5,679 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 Buka Island Airport and Singapore Changi 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 Buka Island Airport and Singapore Changi Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Buka Island Airport (BUA):

• Today the airport is the primary air portal into Bougainville, and even 60 years after the war, wreckage from the military use of the airfield by the Japanese and Americans is easily found in the area.
• Buka Island Airport (BUA) currently has only 1 runway.
• Because of Buka Island Airport's relatively low elevation of 11 feet, planes can take off or land at Buka Island 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.
• There is one navigational aid, the Buka NDB situated on nearby Sohano Island.
• The furthest airport from Buka Island Airport (BUA) is São Filipe Airport (SFL), which is located 11,781 miles (18,959 kilometers) away in Fogo, Cape Verde.
• The closest airport to Buka Island Airport (BUA) is Nissan Island Airport (IIS), which is located 71 miles (114 kilometers) NNW of BUA.

Facts about Singapore Changi Airport (SIN):

• Despite the airport opening in 1981, some sections were not completed.
• Singapore Changi Airport (SIN) has 3 runways.
• The furthest airport from Singapore Changi Airport (SIN) is Francisco de Orellana Airport (OCC), which is nearly antipodal to Singapore Changi Airport (meaning Singapore Changi Airport is almost on the exact opposite side of the Earth from Francisco de Orellana Airport), and is located 12,345 miles (19,868 kilometers) away in Coca, Ecuador.
• The closest airport to Singapore Changi Airport (SIN) is Paya Lebar Air Base (PLAB) (QPG), which is located only 6 miles (9 kilometers) W of SIN.
• Concerned that the existing airport was located in an area with potential for urban growth, which would physically hem it in on all sides, the government subsequently decided in 1975 to build a new airport at the eastern tip of the main island at Changi, at the existing site of Changi Air Base, where the new airport would be easily expandable through land reclamation.
• The first phase costing about S$1.3 billion opened on 1 July 1981 with the first flight, Singapore Airlines Flight 101, touching down at 0700 hours UTC with 140 passengers from Kuala Lumpur.
• In addition to being known as "Singapore Changi Airport", other names for SIN include "Lapangan Terbang Antarabangsa Changi Singapura", "新加坡樟宜机场(Xīnjiāpō Zhāngyí Jīchǎng)" and "சிங்கப்பூர் சாங்கி விமானநிலையம் (Ciṅkappūr Cāṅki Vimana Nilaiyam)".
• The master plan for the existing airport initially involved a dual-terminal and dual-runway configuration over two phases with provisions for another two passenger terminals in the near future.
• Because of Singapore Changi Airport's relatively low elevation of 22 feet, planes can take off or land at Singapore Changi 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.
• To prepare for the arrival of the Airbus A380, the airport put into place modifications works costing S$60 million, which it has planned for since the late 1990s.
