Nonstop flight route between London, England, United Kingdom and Georgetown, Ascension Island, Saint Helena:

About this route:

A direct, nonstop flight between London Heathrow Airport (LHR), London, England, United Kingdom and RAF Ascension (ASI), Georgetown, Ascension Island, Saint Helena would travel a Great Circle distance of 4,190 miles (or 6,744 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 RAF Ascension, 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 RAF Ascension. You'll see that it will travel the same route of the red line on this map!

Facts about London Heathrow Airport (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.
• When runway alternation was introduced, aircraft generated significantly more noise on departure than when landing, so a preference for westerly operations during daylight was introduced, which continues to this day.
• Night-time flights at Heathrow are subject to restrictions.
• London Heathrow Airport (LHR) has 2 runways.
• Terminal 1 opened in 1968 and was formally inaugurated by Queen Elizabeth II in May 1969.
• The furthest airport from London Heathrow Airport (LHR) is Chatham Islands (CHT), which is located 11,875 miles (19,112 kilometers) away in Waitangi, Chatham Islands, New Zealand.

• The closest airport to London Heathrow Airport (LHR) is RAF Northolt (NHT), which is located only 6 miles (9 kilometers) NNE of LHR.
• 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.
• Heathrow Airport started in 1929 as a small airfield on land south-east of the hamlet of Heathrow from which the airport takes its name.
• Heathrow Airport has Anglican, Catholic, free church, Hindu, Jewish, Muslim and Sikh chaplains.
