About this route:
A direct, nonstop flight between Gratiot Community Airport (AMN), Alma, Michigan, United States and London Heathrow Airport (LHR), London, England, United Kingdom would travel a Great Circle distance of 3,758 miles (or 6,047 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 Gratiot Community Airport and London Heathrow 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 Gratiot Community Airport and London Heathrow Airport. You'll see that it will travel the same route of the red line on this map!

- For the 12-month period ending December 31, 2007, the airport had 9,500 general aviation aircraft operations, an average of 26 per day.
- Because of Gratiot Community Airport's relatively low elevation of 754 feet, planes can take off or land at Gratiot Community 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.
- Gratiot Community Airport (AMN) has 2 runways.
- The furthest airport from Gratiot Community Airport (AMN) is Margaret River Airport (MGV), which is located 11,192 miles (18,011 kilometers) away in Margaret River, Western Australia, Australia.
Facts about London Heathrow Airport (LHR):
- The closest airport to London Heathrow Airport (LHR) is RAF Northolt (NHT), which is located only 6 miles (9 kilometers) NNE of LHR.
- As the airport is west of London and as its runways run east–west, an airliner's landing approach is usually directly over the conurbation of London when the wind is from the west.
- 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.
- The airport has been criticised in recent years for overcrowding and delays.
- 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.
- London Heathrow Airport (LHR) has 2 runways.
- 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.
- 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.
- In the 1950s, Heathrow had six runways, arranged in three pairs at different angles in the shape of a hexagram with the permanent passenger terminal in the middle and the older terminal along the north edge of the field, and two of its runways would always be within 30° of the wind direction.
