Carnarvon to Mount MagnetYCAR → YMOG
Carnarvon Airport (YCAR / CVQ) in Carnarvon, Australia to Mount Magnet Airport (YMOG / MMG) in Mount Magnet Airport, Australia is 297 nautical miles — 550 kilometres, or 342 statute miles — on the great circle, on an initial bearing of 132°. A business jet at Mach 0.85 and FL410 takes about 1h 05m 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. YCAR to YMOG is quickest in June (1h 00m) and slowest in January (1h 05m); YMOG to YCAR is quickest in January (1h 10m) and slowest in June (1h 15m). 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 54 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.
The two fields
Questions people ask about this route
How far is it from Carnarvon (YCAR) to Mount Magnet (YMOG)?
297 nautical miles. That is 550 kilometres or 342 statute miles, measured as a great circle between Carnarvon Airport and Mount Magnet Airport.
How long is the flight from Carnarvon to Mount Magnet?
About 1h 05m 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 Carnarvon and Mount Magnet?
In the average upper wind, Carnarvon to Mount Magnet at Mach 0.85 runs from 1h 00m in June to 1h 05m in January, and the return from 1h 10m in January to 1h 15m in June. 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 Carnarvon (YCAR) to Mount Magnet (YMOG)?
132° 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 Carnarvon to Mount Magnet 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.
