About this route:
A direct, nonstop flight between Metlakatla Seaplane Base (MTM), Metlakatla, Annette Island, Alaska, United States and Chimbu Airport (CMU), Kundiawa, Papua New Guinea would travel a Great Circle distance of 6,303 miles (or 10,143 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 Metlakatla Seaplane Base and Chimbu 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 Metlakatla Seaplane Base and Chimbu Airport. You'll see that it will travel the same route of the red line on this map!

- Because of Metlakatla Seaplane Base's relatively low elevation of 0 feet, planes can take off or land at Metlakatla 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.
- Metlakatla Seaplane Base (MTM) has 2 runways.
- The closest airport to Metlakatla Seaplane Base (MTM) is Annette Island Airport (ANN), which is located only 6 miles (10 kilometers) S of MTM.
- The furthest airport from Metlakatla Seaplane Base (MTM) is Port Alfred Airport (AFD), which is located 10,621 miles (17,093 kilometers) away in Port Alfred, South Africa.
Facts about Chimbu Airport (CMU):

- The closest airport to Chimbu Airport (CMU) is Goroka Airport (GKA), which is located 29 miles (47 kilometers) E of CMU.
- Because of Chimbu Airport's high elevation of 4,974 feet, planes must typically fly at a faster airspeed in order to takeoff or land at CMU. Combined with a high temperature, this could make CMU a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
