Earlier this year, a Gulfstream G650ER was flown 6,947 nm (12,866 km) from Los Angeles International Airport to Tullamarine Airport in Melbourne, Australia, at an average speed of Mach 0.86. This flight was accomplished with fuel reserves well in excess of the National Business Aviation Association’s (NBAA) instrument flight rules (IFR) requirements and took 14 hours and 58 minutes into head winds of up to 13 knots.
