The A350-1000 is the largest variant of the A350 family at just under 74 metres in length. It seats 366 passengers in a typical three-class layout with a range of 8,000 nmi (14,800 km). With a 9-abreast configuration, it is designed to replace the Airbus A340-600 and compete with the Boeing 777-300ER and 777-9. Airbus estimates a 366-seat -1000 should have a 35 t lighter operating empty weight than a 398-seat 777-9, a 15% lower trip cost, a 7% lower seat cost, and a 400 nmi (740 km) greater range. Compared to a Boeing 777-300ER with 360 seats, Airbus claims a 25% fuel burn per seat advantage for an A350-1000 with 369 seats. The 7 m (23 ft) extension seats 40 more passengers with 40% more premium area. The -1000 can match the 40 more seats of the 777-9 by going 10-abreast but with diminished comfort.
The A350-1000 has an 11-frame stretch over the −900 and a slightly larger wing than the −800/900 models with trailing-edge extension increasing its area by 4%. This will extend the high-lift devices and the ailerons, making the chord bigger by around 400 mm, optimising flap lift performance as well as cruise performance. The main landing gear is a 6-wheel bogie instead of a 4-wheel bogie, put in a one frame longer bay. The Rolls-Royce Trent XWB engine's thrust is augmented to 97,000 lbf (430 kN). These and other engineering upgrades are necessary so that the −1000 model maintains range.
In 2011, Airbus redesigned the A350-1000 with higher weights and a more powerful engine variant for more range for trans-Pacific operations which will boost its appeal to Cathay Pacific, Singapore Airlines, which committed to 20 777-9, and United Airlines, which could turn to 777-300ERs to replace its 747-400s. Emirates was disappointed with the changes and cancelled its order for 50 A350-900s and 20 A350-1000s instead of citing the whole order to the larger variant.
Assembly of the first fuselage major components started in September 2015. In February 2016, final assembly started at the A350 Final Assembly Line in Toulouse. Three flight test aircraft was planned with entry into service scheduled for mid-2017. The first aircraft completed its body join on 15 April 2016. Its maiden flight took place on 24 November 2016.
The A350-1000 flight-test programme planned for 1,600 flight hours; 600 hours on the first aircraft, MSN59, for the flight envelope, systems and powerplant checks; 500 hours on MSN71 for cold and warm campaigns, landing gear checks and high-altitude tests; and 500 hours on MSN65 for route proving and ETOPS assessment, with an interior layout for cabin development and certification. In cruise at Mach 0.854 (912 km/h; 492 kn) and 35,000 ft, its fuel flow at 259 t (571,000 lb) is 6.8 t (15,000 lb) per hour within a 10,000 km (5,400 nm), 11 h 30 m early long test flight. Flight tests allowed raising the Maximum Take-Off Weight from 308 to 316 t (679,000 to 697,000 lb), the 8 t (18,000 lb) increase giving 450 nmi (830 km) more range. Airbus then completed functional and reliability testing.
Type Certification was awarded by EASA on 21 November 2017, along FAA certification. The first serial unit was on the final assembly line in early December. After its maiden flight on 7 December, delivery to launch customer Qatar Airways slipped to early 2018. The delay was due to issues with the business class seat installation. It was delivered on 20 February and entered commercial service on Qatar Airways' Doha to London Heathrow route on 24 February.
It features an automatic emergency descent function to around 10,000 ft (3,000 m) and notifies air traffic control if the crew fails to respond to an alert, indicating possible incapacitation from depressurisation. The avionics software adaptation is activated by a push and pull button to avoid mistakes and could be retrofitted in the smaller -900. All performance targets have been met or exceeded and it remains within its weight specification, unlike early −900s.Its basic 308 t (679,000 lb) maximum take-off weight was bumped to 311 t (686,000 lb) before offering a possible 316 t (697,000 lb) version. Its 316 t MTOW appeared in the 29 May 2018 update of its type certificate data sheet. This raised its range from 7,950 to 8,400 nmi (14,720 to 15,560 km). A further MTOW increase by 3t to 319t is under study to be available from 2020 and could be a response to Qantas' Project Sunrise.
Cathay Pacific Airways Limited is the flag carrier of Hong Kong, with its head office and main hub located at Hong Kong International Airport. The airline's operations and subsidiaries have scheduled passenger and cargo services to more than 190 destinations in more than 60 countries worldwide including codeshares and joint ventures. Cathay Pacific operates a fleet of wide-body aircraft, consisting of Airbus A330, Airbus A350 and Boeing 777 equipment.
