As Airbus and Boeing battle for orders for the current generation A320 and 737 families and for the re-engined models, comparisons between the four sets of aircraft has been difficult to come by.
Furthermore, with Boeing continuing to evolve the MAX–not only with the engine specifications but also the airplane weights–ambiguity sometimes dominates.
Boeing continues to talk with customers about the definition of the MAX, with higher weights under study. Airbus is more advanced, but of course until flight testing confirms figures, nothing is certain.
Over time, information as emerged through Airbus, Boeing, Pratt & Whitney and other statements and information. Aspire Aviation (now Orient Insight) also has been a solid source of information. Our own data gathering has obtained some solid information as well.
From all these sources, we’ve put together the following table. The 737-7 MAX is the murkiest, with little apparent interest so far from the customer base. Taking known facts for the 8/9 MAX, we estimated some of the specifications for the 7 MAX.
What struck us on the NEO is that Airbus specifications for range are greater than has been previously revealed.
We consider the specifications of NEO and MAX still evolving until flight tests for all six sub-types prove design goals.
