Qantas sets new speed record for Perth to London non-stop flight
Qantas Airways has set a new speed record for its QF9 non-stop flight on Boeing 787-9, slicing almost an hour off the scheduled time. The Perth to London and return service, launched earlier this year, has been consistently beating the set schedule in both directions, thanks to favorable summer weather patterns.
The new record time of Flight QF9 was set on July 20, 2018, and was just 16 hours 23 minutes instead of the scheduled 17 hours 20 minutes, Airline Ratings reports. Since it was launched in March, 2018, Qantas‘ non-stop service from Perth to London has consistently logged in at least 45 minutes better time than scheduled.
For instance, the latest flight on that route on August 13, 2018, took just 16 hours 35 minutes to complete. That is compared to the inaugural flight on March 24, 2018, which took 17 hours and 12 minutes for the Qantas Dreamliner to complete.
According to Airline Ratings, the inbound Flight QF10 from London to Perth is also setting record times - logging in 15 hours and 45 minutes and slashing an hour off the scheduled time. For instance, on August 12, 2018, the journey took just 15 hours and 47 minutes to complete.
The average speed for Flight QF10 is about 582 m/h (936 km/h) with ground speeds topping out at over 696 m/h (1120 km/h). The typical cruise speed for the Qantas Boeing 787 is 559 m/h (900 km/h) or Mach 0.85 at maximum cruise altitude of 13,106 ft (4 km).
Qantas currently has five 787-9s in its fleet with the sixth being in pre-delivery.
Here are some interesting facts about the Perth to London Flight QF9:
Across the up to 17-hour journey, the Boeing 787-9 is operated by four pilots, with one or two resting at any one time. The flight will follow different flight paths depending on the best winds, helping the Dreamliner fly faster and more efficiently. Qantas says it analysed a decade of seasonal wind patterns in preparation for the new service.
At 9,008 miles (14,498 km), the QF9 is the third longest commercial flight currently in operation and the world’s longest Dreamliner flight. The aircraft will carry around 92 tons or 110,000 liters of fuel while burning approximately 20% less than traditional jetliners its size.
With a total seat count of 236 passengers, the Qantas Dreamliner has significantly fewer seats than many other airlines who have configured the same aircraft to carry more than 300 passengers. Currently, most aircraft have cabin air pressure equivalent to that of an altitude of 8,000 ft (2.44 km). For the Dreamliner, Boeing cut that down to 6,000 ft (1.83 km), meaning it is closer to conditions on the ground.
