A: Ed Williams' Aviation Formulary has an example which calculates this distance from LAX to JFK as 2144 nm while the Great Circle Mapper says LAX to JFK is 2151 nm . This comes from several simplifying assumptions in the Aviation Formulary example:
- Great Circle Mapper
The Great Circle Mapper displays maps and computes distances...

const c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a)); const d = R * c; // in metres. Note in these scripts, I generally use lat/lon for latitude/longitude in degrees, and φ/λ for latitude/longitude in radians – having found that mixing degrees & radians is often the easiest route to head-scratching bugs...
import pyproj. # calculate distance between points. g = pyproj.Geod(ellps='WGS84') (az12, az21, dist) = g.inv(startlong, startlat, endlong, endlat) # calculate line string along path with segments <= 1 km. lonlats = g.npts(startlong, startlat, endlong, endlat, 1 + int(dist / 1000)) # npts doesn't include start/end points, so prepend/append them.
Compute the great circle route from Valparaíso , φ 1 = −33°, λ 1 = −71.6°, to Shanghai , φ 2 = 31.4°, λ 2 = 121.8°. The formulas for course and distance give λ 12 = −166.6°, [note 8] α 1 = −94.41°, α 2 = −78.42°, and σ 12 = 168.56°. Taking the earth radius to be R = 6371 km, the distance is s12 = 18743 km.
