The Revolutionary GTF Engine


Pratt & Whitney's GTF™ engine, with its revolutionary geared fan technology, is transforming aviation by delivering game-changing economic and environmental performance. It is the architecture of choice, and customers love its performance and design.

The engine's fan-drive gear system is just one component of this next-generation engine. The GTF engine also incorporates advances in aerodynamics, lightweight materials and other major technology improvements in the compressor, turbine, combustor, controls, engine health monitoring and more. The GTF engine has met all performance specifications since entering into service, achieving up to 20% reduction in fuel burn, 50% lower regulated emissions and a 75% smaller noise footprint.

Saving nearly 100 gallons of fuel and a full metric tonne of carbon emissions per flight hour, the GTF engine is powering the next-generation of efficient, sustainable air travel, allowing airlines and airports to open new routes and fly more people, farther, with less fuel – and much lower noise.


The GTF leads a new era of commercial jet engines for India, powering a large fleet of Airbus A320neo family aircraft at IndiGo and GoAir. Given the GTF’s unmatched fuel efficiency and runway for growth, India became early adopter of the engine in 2016.

As the GTF crosses the 5 years of service milestone in India, the engine has contributed to lower fares and new routes. Today the engine has flown more than 2 million engine flight hours, carrying over 110 million passengers since its induction.  The GTF lets our customers not only fly further with the same fuel load, but also take more efficient flight routes.

The engine family is now delivering world-class dispatch reliability of 99.98% in addition to its superior economic and environmental benefits.


At Pratt & Whitney, we offer a comprehensive engine maintenance, repair and overhaul (MRO) services and support, backed by a global state-of-the-art service network of owned and designated facilities. The GTF MRO network is part of the Pratt & Whitney EngineWise® service portfolio, which delivers a variety of aftermarket services for long-term, sustainable value.

Throughout 2020, we expanded this network to nine facilities, and we will have 11 active GTF MRO engine centers by 2021. Air India Engineering Services Limited (AIESL) was announced as a provider of maintenance services in support of GTF operators in India in 2020. We have strong, 20-year history with AIESL, which has previously overhauled engines like our JT8D, JT9D and PW4000.

The establishment of an aircraft engine MRO in India offers multiple benefits:


The GTF engine is delivering game-changing performance across three in-service aircraft platforms – the Airbus A320neo, Airbus A220 and Embraer E-Jets E2 families – with additional aircraft in development. Learn more at
