Introduction

August 1, 2019, © Leeham News: We wrap up our study of what part of an NMA market the Airbus A321XLR could capture with looking at the difference in available engine technology between the A231XLR and the NMA generation of airliners.

Summary:

• The generational improvement in fuel efficiency of airliner turbofans has been over 10% in the last decades.
• We examine if these improvements will still be the case for the NMA generation of aircraft.
