On Monday (May 22, 2023), Pratt & Whitney Canada announced the launch of their PW545D engine which will power the new Cessna Citation Ascend, Textron Aviation’s newest business jet. The engine was specifically designed for Textron to deliver improved specific fuel consumption (SFC), thrust and time between overhauls (TBO). Building on the success of the PW545C, the PW545D incorporates new materials and technologies, including a more efficient high-pressure compressor, and enhanced single-stage high pressure turbine module, and an advanced exhaust mixer to reduce fuel consumption and noise. The new PW545D is also equipped with Full Authority Digital Engine Control (FADEC) technology, which is included with many PW500 models. This enables the Citation Ascend to integrate new auto-throttle technology that simplifies control, maximizes efficiency and reduces pilot workload.

In today’s announcement, Pratt & Whitney’s Vice President – General Aviation, Nicholas Kanellias, said,

“The PW500 turbofan family has established itself as the engine of choice for light to mid-size business jets thanks to its proven safety, reliability and durability, attractive operating economics and comprehensive maintenance plans. The PW545D is the latest engine in this family. We injected all we've learned from the more than 4,600 PW500 engines produced to-date, which have accumulated over 22 million flying hours. This new engine is even more fuel-efficient, offers greater thrust and an increased TBO of up to 6,000 hours for eligible customers.”

Pratt &Whitney Canada’s new PW545D engine also supports digitally-driven advanced health monitoring and diagnostics, in combination with FAST™ (Flight, Acquisition, Storage and Transmission) system. With FAST, the engine’s full flight data is downloaded, stored and analyzed by experts, enabling deep insights and predictive diagnostics to optimize performance and maintenance requirements. Customers with FAST installed who are enrolled in Pratt & Whitney’s Eagle Service™ Plan (ESP™) pay-per-hour maintenance program can take advantage of the 6,000 TBO option. The PW545D can operate on blends of up to 50 percent SAF with conventional Jet A kerosene.

This year, Pratt & Whitney Canada is celebrating 1.0 billion flights hours for their entire engine fleet, of which, 350 million flying hours can be attributed to powering Textron Aviation’s fleet.
