12 April, 2015: In our study of the options for Boeing’s market study called Middle of the Market (MOM), we could conclude that the most likely aircraft to cover their 200-250 seat 4750nm range requirement would be a seven abreast twin aisle aircraft using their patented new oval construction, thereby saving weight and drag.
After finishing the series, Readers requested that we conclude the work by showing what market segment a family of such airliners would cover and how they would relate to the Boeing 787-8. As it is pretty straight forward to see with our aircraft performance model how much of a range of aircraft variants one can make from one base development of aircraft and engine, we decided to fulfill the wish from our Readers.
We have therefore looked at how far the concept MOM airliner could be stretched and what segment in the market would be covered by it. We also studied how much such a family would encroach on Boeing’s 787 Dreamliner market.
A base design such as our proposed MOM dual aisle airliner can typically cover a market of 30-40 seat increments per model.
Limiting factors are the base models wing area and span, together with engine sizing. Much depends on the engine’s stretch capability.
A MOM airliner family would compete with the 787-8 for short- and mid-haul traffic, there presenting a more economical alternative. The Dreamliner would have long-haul for itself.
