Nonstop flight route between London, England, United Kingdom and Kathmandu, Nepal:

About this route:

A direct, nonstop flight between London Heathrow Airport (LHR), London, England, United Kingdom and Tribhuvan International Airport (KTM), Kathmandu, Nepal would travel a Great Circle distance of 4,573 miles (or 7,359 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 London Heathrow Airport and Tribhuvan 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 London Heathrow Airport and Tribhuvan International Airport. You'll see that it will travel the same route of the red line on this map!

Facts about London Heathrow Airport (LHR):

• The original 1950s red-brick control tower was demolished in early 2013 to enable access roads for the new Terminal 2 to be laid.
• Of Heathrow's 69 million passengers in 2011, 7% were bound for UK destinations, 41% were short-haul international travellers and 52% were long-haul.
• Because of London Heathrow Airport's relatively low elevation of 83 feet, planes can take off or land at London Heathrow 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.
• London Heathrow Airport (LHR) has 2 runways.
• The closest airport to London Heathrow Airport (LHR) is RAF Northolt (NHT), which is located only 6 miles (9 kilometers) NNE of LHR.
• A trial of "noise relief zones" ran from December 2012 to March 2013, which concentrated approach flight paths into defined areas compared with the existing paths which were spread out.
• Heathrow Airport is used by over 90 airlines flying to 170 destinations worldwide.
• Policing of the airport is the responsibility of the aviation security unit of the Metropolitan Police, although the army, including armoured vehicles of the Household Cavalry, has occasionally been deployed at the airport during periods of heightened security.
