Gulfstream's latest G500 and G600 business jets will be powered by Pratt & Whitney PurePower PW814GA and PW815GA engines, which have now received type certification from Transport Canada.

During rigorous endurance testing that simulated various aircraft missions, the engine has achieved more than 3,300 hours of evaluation. This includes over 350 flight hours on P&W's Boeing 747SP flying test bed aircraft. Additionally, the core technology – used in six PurePower engine applications – has amassed 15,000 testing hours in total.

Among features of the PurePower engines are a high efficiency and low maintenance single-piece fan, full authority digital engine control system with advanced diagnostics, and lightweight, advanced materials. They are said to deliver fuel efficiency with double digit improvement over the previous generation of engines in this thrust class.
