For decades, commercial passenger aircraft relied on a system that tapped pressurized air directly from the engines to pressurize and condition the cabin. That bleed air system has worked well for years, but comes with some limitations in terms of efficiency, complexity, and even passenger comfort. So when it came to designing the Boeing 787 Dreamliner, the US manufacturer took a bold new approach, rethinking how cabin air is delivered, conditioned, and distributed.

This has very little to do with the avionics and airframe design, and is pretty much all about the engines powering the jet – the Pratt & Whitney PW1500G geared turbofan engine. So this prompts us to ask the question: Should the Airbus A220 get a 2nd engine option?
