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?

The worst point on the great circle is 1h 14m from the nearest suitable airport, Yuzhno-Sakhalinsk (UHSS), at the one-engine diversion speed Overfly uses (430 kt in still air). A twin flying this track needs ETOPS 120 approval or more: ETOPS 120 allows up to 120 minutes from an alternate.

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.
