COLORADO SPRINGS—As Bombardier continues certification tests of the extended-range Global 8000, company test pilots have provided new details of the unusual supersonic flight-test campaign conducted last year off the California coast.  

Flight testing for the fastest and longest-range purpose-built business jet is being conducted using FTV-5, a development Global 7500 aircraft on which the new variant is based. Tests at supersonic speeds were required as part of plans to certificate the Global 8000 with a maximum Mach operating speed (MMO) of Mach 0.94, versus the Global 7500’s top speed of Mach 0.925.

Bombardier’s high-speed test campaign culminated in May 2021 when FTV-5 repeatedly achieved supersonic speed in shallow dives, reaching Mach 1.015 off California’s Pacific coast. The tests marked the fastest flight of a civil aircraft since the retirement of the Anglo-French Concorde and the first transport category aircraft to fly supersonically with sustainable aviation fuel.
