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 15 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 Sandino (MUSJ) to Cayo Largo del Sur (MUCL)?

148 nautical miles. That is 274 kilometres or 170 statute miles, measured as a great circle between San Julián Air Base and Vilo Acuña International Airport.

How long is the flight from Sandino to Cayo Largo del Sur?

About 0h 50m 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 Sandino (MUSJ) to Cayo Largo del Sur (MUCL)?

101° 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 Sandino to Cayo Largo del Sur 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.
