PRATT & WHITNEY ANNOUNCES CERTIFICATION OF REGIONAL TURBOPROP ENGINE

Pratt & Whitney Canada, a business unit of Pratt & Whitney, announced that Transport Canada Civil Aviation has type certified the PW127XT-M regional turbo

prop engine that will power new builds of ATR aircraft.

“The PW127XT-M engine is the new standard for operating economics, maintenance and sustainability for regional aircraft,” said Timothy Swail, Vice President, Regional Aviation and APU Product Marketing & Sales for Pratt & Whitney Canada. “This certification is an important step toward the entry into service of new ATR aircraft and we continue to support ATR as it builds a strong order book.”

Revealed at the Dubai Airshow in November 2021, the PW127XT-M engine offers 40 per cent extended time on wing, 20 per cent lower maintenance costs and 3 per cent improvement in fuel efficiency, due to engine improvements making the regional turboprop even more sustainable. Regional turboprops currently boast up to 40 per cent improvement in fuel efficiency compared with similar missions for the 30-70 passenger regional jet aircraft market.

All Pratt & Whitney engines and Embraer aircraft are currently certified to operate with SAF blended up to 50 per cent with standard Jet A/A1 kerosene, according to ASTM International specifications. Future specifications will enable blends of up to 100 per cent SAF to maximise the emissions reduction potential of using fuel derived from sustainable, non-fossil-based feedstocks.

The SAF used by Embraer and Pratt & Whitney was 100 per cent Hydroprocessed Esters and Fatty Acids Synthetic Paraffinic Kerosine (HEFA-SPK) acquired from World Energy. HEFA-SPK is a specific type of hydrotreated renewable feedstock fuel used in aviation and is considered a leading alternative replacement for conventional jet fuel by the Commercial Aviation Alternative Fuels Initiative (CAAFI), due to the sustainability of its feedstock.

The P&W GTF engine is the only geared propulsion system delivering industry-leading sustainability benefits and world-class operating costs. It is the exclusive powerplant of the Embraer E-Jets E2 family.
