Nonstop flight route between Asmara, Eritrea and Hanoi, Vietnam:

About this route:

A direct, nonstop flight between Asmara International Airport (ASM), Asmara, Eritrea and Nội Bài International Airport (HAN), Hanoi, Vietnam would travel a Great Circle distance of 4,378 miles (or 7,046 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 Asmara International Airport and Nội Bài International 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 Asmara International Airport and Nội Bài International Airport. You'll see that it will travel the same route of the red line on this map!

• Because of Asmara International Airport's high elevation of 7,661 feet, planes must typically fly at a faster airspeed in order to takeoff or land at ASM. Combined with a high temperature, this could make ASM a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
