IndiGo Selects Pratt & Whitney EcoPower® Engine Wash

PARIS AIR SHOW, Wednesday, June 22, 2011

IndiGo has signed a long-term agreement with Pratt & Whitney to use the company's environmentally responsible EcoPower® engine wash service on the airline's fleet of Airbus A320 aircraft. Pratt & Whitney is a United Technologies Corp. (NYSE: UTX) company.

Through this agreement, IndiGo will receive approximately 200 washes annually on its growing fleet of V2500-powered A320s. The washes will be performed at the Mumbai International Airport.

"We selected EcoPower engine wash because of the unmatched environmental and financial benefits it offers," said Aditya Ghosh, IndiGo president. "This agreement also allows us to increase the operational efficiency of our growing fleet."

"IndiGo works hard to keep costs down and stay on schedule without compromising the customer's experience," said Lou Quattrocchi, Pratt &Whitney Product Line Management vice president. "EcoPower engine wash will help IndiGo continue to do this by decreasing its fuel expense and keeping its engines on wing longer."

IndiGo is India's largest low-fare airline with its headquarters in Gurgaon, Haryana, India and its Main Base in Delhi. The airline operates 259 daily domestic flights linking 26 destinations throughout India. IndiGo was recently awarded the award for Best Performing Airbus A320 Family Operator in Asia Pacific/Middle East/ Africa at Airbus A320 symposium held in Toronto in May, 2011. This was based both on fleet utilization and performance achievements in the Fleet Size category of more than 30 aircraft.

Pratt & Whitney's patented EcoPower engine wash system reduces fuel burn by as much as 1.2 percent, eliminating approximately three pounds of carbon dioxide emissions for every pound of fuel saved, while also decreasing engine gas temperature, increasing the amount of time an engine can stay on wing. Pratt & Whitney is a world leader in the design, manufacture and service of aircraft engines, space propulsion systems and industrial gas turbines. United Technologies, based in Hartford, Conn., is a diversified company providing high technology products and services to the global aerospace and commercial building industries.
