Calculation steps

  1. 1Haversine: a = sin²(Δφ/2) + cosφ₁·cosφ₂·sin²(Δλ/2); d = 2R·asin(√a)
  2. 2R = 6371.0088 km (IUGG mean Earth radius)
  3. 3Δlat = -8.6738°, Δlon = 5.0663°
  4. 4d = 1067.3 km
Kilometers1067.3 km
Miles663.2 mi
Nautical miles576.3 nm
Flight time (800 km/h)1.3 h

Classic routes reference

RouteGreat-circle distance
Beijing → Shanghai1067 km
Beijing → Guangzhou1889 km
Beijing → New York10989 km
Shanghai → Tokyo1754 km
London → New York5570 km
Tokyo → Sydney7826 km
The great-circle path is the shortest route on a sphere — long-haul flights curve toward the poles for this reason (Beijing–New York flies over the Arctic, not the Pacific). Actual flight routes are 5–15% longer due to winds, airspace and ETOPS rules. Driving/rail distance is typically 1.2–1.4× the straight-line figure.
