There are actually regulations about how far an airplane can be from land - it's why so many flight paths are similar (US-Scotland overlaps US-Paris, for example).
You can use this website to see the true flight path for the Johannessburg flight: http://dl.fltmaps.com/en http://dl.fltmaps.com/en [enter Atlanta and Johannesburg as the endpoints]
EDIT: Can't find an FAA source about distances to airport, but here's a related Wikipedia page. https://en.wikipedia.org/wiki/ETOPS https://en.wikipedia.org/wiki/ETOPS
- mseebach 10y agoThat map does not show true flight paths, those are heavily stylised. This is a true flight path, and it's much closer to the great circle: https://www.flightradar24.com/DAL200/ae190b1 https://www.flightradar24.com/DAL200/ae190b1
- ejstronge 10y agoYou're right - I didn't realize those maps were stylized. Thanks for the correction!
