The aircraft that made the news at last week's 50th Paris air show are largely enabled by advances in propulsion technology that allow their manufacturers to offer big reductions in fuel burn over the previous generation of airliners. The savings of 15% or more are driving the orders. Whether it is the Airbus A320NEO with the CFM International Leap-1A or Pratt & Whitney PW1100G, Boeing 737MAX with the Leap-1B, Bombardier CSeries with the PW1500G, Embraer E-Jet E2 with the PW1700/1900G or Mitsubishi MRJ90 with the PW12000G, the engines are critical.
