CESL2G (PWA212040)

You've got the best engine.

Now get the best engine software loader.

Your Pratt & Whitney GTF™ engines operate best when they have the latest software installed, and there's no better tool for you to keep your engine software up to date than the Bloomy Common Engine Software Loader (Second Generation). The result of collaboration between Pratt & Whitney and Bloomy, the Bloomy CESL2G is a clean-sheet design with reliability, safety, and convenience incorporated from the project’s inception. The Bloomy CESL2G is also the only GTF software loader which was designed from the ground up to address feedback from operators learned from the last generation of GTF software loaders.

Reliable, Rugged, and Compliant

The Bloomy CESL2G is the premier solution for interacting with the Pratt & Whitney Geared Turbofan engine family. Because software is such an integral part of modern turbofan engines, you can't risk your fleet's performance on anything less than the Bloomy CESL2G. After all, if a software update can increase the time between services and reduce the cost of operation, why would you trust your engines to anything but the very best?

With a superior reliability record, the Bloomy CESL2G fleet has earned a repuation for being able to meet the stringent needs of GTF operators, both large and small.

Keeping aircraft in the air is your business. We make it our business to see that they stay there.

Safety isn't optional.

You already work in a dangerous environment, so we’ve designed the Bloomy CESL2G with your safety in mind. As a result of these painstaking efforts, the Bloomy CESL2G is proud to wear the both the CE Mark and TÜV Logo signifying that it has passed over 800 independently-conducted safety inspections, measurements, and tests.

We know you value your customers’ safety. At Bloomy, we do, too.



Whether you’re checking it as luggage or shipping it via freight, you need to know that your software loader is going to arrive unbroken and ready to go. So we designed the Bloomy CESL2G to withstand the ramp’s “best” handling, and then we put it through stringent military-standard drop, shock, and vibe tests. And if that weren’t enough, we then dropped it from 36”—twice what the military requires! (It survived just fine.) Heavy-duty components, from case to tablet, and our expert design means your Bloomy CESL2G will arrive ready for duty—even if it did get dropped off a baggage cart!
