Hi folks, I put on some ideas on a 200-300 seat medium haul aircraft. IMO there is a large gab between the A321/737-900ER and the A330-200 / 787 / A350 which are significant larger / twice as heavy and are optimized for long haul (including LD3's).Ther is a large replacement market for A300/310, 757-200, 757-300, 767-200, 767-300s that need to be replaced in the next decade. Currently offered aircraft don't seem to fit the requirement. The 787-3 is twice as heavy as the A321 /737-900ER. Both A321 (max 220 seats) and 787-3 (max 330 seats) are not Transatlantic. I tried to summarize everything in 1 picture.
What do you think?
Goose you are right 2-2-2 doesn't make economic sense in current aircraft segments. However I think traditional single aisle isn't practicle for short haul 300 seat flights. I assume the 2-2-2 makes possible smaller pitches and narrower seats then 3-3 and enabling fast (de)boarding. Note some of the middle seats are folding and the center bins are high for people to easily move around. Making a very long thin aircraft put limits on how stiff you can make without adding to much weight. In premium classes a 20% wider fuselage could make possible 5 abreast domestic first (you can't have middle seats there) and a competetive 4 abreast medium / long haul business class.
I think the size of the 130-250 replacement market justifies a bigger variant and a smaller one. Combining them would create inefficiencies not allowable in the current market situation. Say Boeing comes up with an aircraft that covers the 130-250 seat range and 2 years later Airbus comes up with an optimized max 175 seater that is 20% lighter..
I made a little indicative picture of the market including some concepts..
