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 29m from the nearest suitable airport, Asyut (HEAT), 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.

How long is the flight from Matan al-Sarra Air Base to Geneina?

About 1h 30m block time for a business jet cruising at Mach 0.85 at FL410 in still air, including 30 minutes of taxi, climb and descent. Wind moves that figure in either direction — eastbound across the North Atlantic or the Pacific it can be an hour or more. This page is deliberately still-air so the figure is stable and citable; to apply the month's average upper winds from NOAA, open the route in the mapper and switch on seasonal winds.

What is the initial bearing from Matan al-Sarra Air Base (HL56) to Geneina (HSSG)?

175° true at the departure point. A great circle changes heading continuously, so this is the initial bearing, not a constant one.
