Pratt & Whitney Canada PW545D
Pratt & Whitney Canada PW545D turbofan, the latest PW500-family derivative selected as the twin-engine powerplant for Textron Aviation's Cessna Citation Ascend. Pratt & Whitney describes improved specific fuel consumption, thrust, and time between overhauls; Transport Canada type-certified the model in May 2024, while current service material supports the model. Lifecycle is kept at development because the available evidence establishes certification and intended entry-into-service application, not confirmed fleet entry.
