Can the aeroplane make it?

Range here is usable range — book range at long-range cruise, less a reserve allowance. It is the figure that decides whether the leg closes, and it is the question most mappers do not answer.

How far from an airport?

Nowhere on the great circle is more than 12 minutes from a suitable airport at the one-engine diversion speed Overfly uses (430 kt in still air), so a twin-engine aircraft flies it under the 60-minute rule, with no ETOPS approval needed.

A suitable airport here is one OurAirports classes as large with a runway of 8,000 ft or more. An operator’s real alternates also depend on weather, fire cover and approval, and its diversion speed on the type. More in equal-time points and ETOPS, explained.
