The Global Express XRS was announced on 6 October 2003 during the NBAA Convention at Orlando, Florida. Global 6000 Production of the third-generation Global 6000 started in 2012. Its flexible wing and wing loading, the highest among its competitors, gives a comfortable ride in turbulence. On long trips, its fuel burn during the first hour is for the second, then for the third afterwards. A Checks are scheduled every 750 hours, and for C Checks every 30 months, while engine reserves amount to $260 per hour. Over 315 were delivered by March 2019, while its competitors include the more fuel-efficient Dassault Falcon 8X, the Gulfstream G600 or even the G650. Bombardier's Vision flight deck is upgraded with Rockwell Collins Pro Line Fusion avionics from the Express/XRS Honeywell Primus 2000. It has improved acoustical insulation compared to its predecessor. In 2018, its unit cost was US$62.31 million, but competition from the Gulfstream G650ER pressured it to a $40 million value from $62 million in 2016. It offers higher cruise speed, improved cabin layout and lighting. The range is increased by adding a 1,486 lb (674 kg) fuel tank at the wing root. Global 5500/6500 On 27 May 2018, Bombardier unveiled the Global 5500 and 6500 developments expected to enter service at the end of 2019 with an optimized wing for a Mach 0.90 top speed, a revamped cabin inspired from the Global 7500 with its Nuage seat and updated Rolls-Royce BR710 Pearl engines with up to 13% lower fuel burn for better operating costs, better hot and high performance and of additional range for , respectively. The engines have 9% more thrust, their certification was announced and are already test flying. The Global 5500 lists for $46 million while the Global 6500 lists for $56 million. By October, 70% of the flight testing hours were completed. The programme involves two flight-test Global 6500s, as the 5500 is a simple shrink. The redesigned wings are built by Mitsubishi Heavy Industries. By December, the flight-test program was nearly three-quarters complete. By May 2019, 90% of the flight testing was completed by two modified 6000s and one modified 5000. On 24 September, Bombardier announced the Transport Canada Type Certification of both models, before entry-into-service later in 2019 and FAA/EASA approval. Bombardier announced the Global 6500 entry-into-service on 1 October. EASA Type Certification of both models was announced on 15 October 2019. Shortly after, the
