Djanet to SabhaDAAJ → HLLS
Tiska Djanet Airport (DAAJ / DJG) in Djanet, Algeria to Sabha Airport (HLLS / SEB) in Sabha, Libya is 316 nautical miles — 585 kilometres, or 364 statute miles — on the great circle, on an initial bearing of 058°. A business jet at Mach 0.85 and FL410 takes about 1h 10m block time in still air.

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.
Wind, month by month
The same business jet at Mach 0.85 and FL410, in each month’s average upper wind. DAAJ to HLLS is quickest in January (1h 05m) and slowest in July (1h 10m); HLLS to DAAJ is quickest in June (1h 10m) and slowest in February (1h 20m). The wind column is the average along-track component: plus is a tailwind.

Monthly means for 1991–2020 from NOAA’s NCEP/NCAR Reanalysis, at the pressure level nearest the cruise (about FL387), along the great circle. An average is smoother than any one day’s jet stream, so a given flight can see much more or much less; airlines also move the track to use the wind, which this does not. More in how wind changes block time.
How far from an airport?
Nowhere on the great circle is more than 40 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.

Questions people ask about this route
How far is it from Djanet (DAAJ) to Sabha (HLLS)?
316 nautical miles. That is 585 kilometres or 364 statute miles, measured as a great circle between Tiska Djanet Airport and Sabha Airport.
How long is the flight from Djanet to Sabha?
About 1h 10m 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.
How much does wind change the flight time between Djanet and Sabha?
In the average upper wind, Djanet to Sabha at Mach 0.85 runs from 1h 05m in January to 1h 10m in July, and the return from 1h 10m in June to 1h 20m in February. Those are 1991–2020 monthly means from NOAA's reanalysis; on a given day the jet stream can make the difference larger or smaller.
What is the initial bearing from Djanet (DAAJ) to Sabha (HLLS)?
058° true at the departure point. A great circle changes heading continuously, so this is the initial bearing, not a constant one.
Which aircraft can fly Djanet to Sabha non-stop?
Of the types Overfly carries, G650ER, G550, Global 7500, Falcon 8X, Falcon 7X, Challenger 350, A350-900, B777-300ER, A320neo, A320, B737 MAX 8, B737-800, An-124, Concorde, King Air 200, ATR 72, Dash 8 Q400 clear it on usable range — that is book range less a reserve allowance.
