LAS VEGAS—Just over a decade after the first flight of Pratt & Whitney Canada’s (P&WC) PW800 on a business jet, the engine family has now surpassed the 600,000 flight-hour milestone powering the Gulfstream G500/600 and Dassault Falcon 6X.
With over 700 engines in service for 250 operators, production is also expanding to include the new PW812GA variant for the smaller Gulfstream G400, which made its first flight in August 2024. Pratt says it is providing development engines to Gulfstream, which is expected to debut the large-cabin twinjet in 2026.
Based on the high-pressure core of Pratt & Whitney’s PW1000G geared turbofan, the 14,000-lb.-thrust PW814 entered service on the G500 in September 2018, while the first 15,000-lb.-thrust PW815 followed it into operation on the G600 in 2019. A third family member, the 12,000-lb.-thrust PW812, was developed for the Dassault Falcon 6X, which entered service in late 2023.
P&WC’s recently developed PW545D turbofan will meanwhile make its NBAA debut this week on Textron Aviation’s Cessna Citation Ascend midsize jet—the first production unit of which was rolled out in Wichita in September. The engine, which is based on the two-shaft architecture of the long-running PW500 family, received certification from Transport Canada and EASA in 2024 and 2025, respectively.
The 4,200 lb.-thrust engine is the most powerful variant of the PW545 series and incorporates a redesigned high-pressure (HP) compressor for increased flow, an improved single-stage HP turbine module, and an advanced low-noise exhaust mixer.
