Average cabin width (without 20 inch aisle(s)) at shoulderheight per passenger would have my preference. Sidewall shape, armrest number/ width, aislewidth give too much opportunity for creativity / perception management with seat(bottom, cushion)width.Jump to post

Hi, does anybody have an indication on the costs per year of flying around 1kg extra? Of course this would depend on e.g. flight hours, flights, operations, specific aircraft type and fuel prices. Are there any rules of tumb airlines use making trade-off? E.g. when buying cheaper, but heavier interi...Jump to post
It seems Airbus has as many A321NEO versions in their backlog today, as Boeing hopes to sell NMA’s over the next 25 years. That is complicating the NMA costprice for airlines. Boeing is looking at ways to get cost down, by sqeezing their supply chain and working the numbers. Total “Enterprise” long ...Jump to post

Maybe if they can reduce costs in the future it will become viable again. The 757 / 767 getting old & expensive / not being right sized.

There are more then 600 A330-200s in service since 1998, so there will probably some more replacements.
I really don't think that bump between the wings is doing anything to generate lift. It's just there because the structure that most efficiently supports the wings is passing through. If that part of the fuselage is aerodynamically important to lift-generation, then why is there no deicing boot up ...Jump to post
Remember A330neo lost market share because airbus lost precious time, if they had a330neo in 2010 when Boeing was struggling with batteries they might not lose all big customers. Now they have only AirAsia and small niche customers. Practically Airbus launched A330neo in 2006, but it doesn't succee...Jump to post
That's a nice image and all, but I fail to see how the top of the fuselage is acting as a lifting surface, given the absence of leading edge, trailing edge, and underside, all of which are required for an aerofoil to function. Unless the high wing is on struts, raised above the fuselage like an old...Jump to post

We are old enough to have seen the huge interest in the 747Advanced, NSA, 737-7, 777X and 737-9. Thats more communication, creating enthousiasm.
Still I think there is a significant demand, regardless how a medium aircraft would exactly look or what engines it would have.

737MAX200 = 737-8 without toilet / galley? IMO it is marketing to emphasize the 737-8 higher capacity then A320. The 737-9 has higher capacity but higher CSAM/ performance restrictions. The A321 has around 42-48 seats more than the A320.Jump to post

Airbus and Boeing are talking to a lot of airlines on their NMA and A321 development plans. Some airlines show a lot of interest in the Airbus A321XLR or Boeing NMA, some do not.

I thought about this. A small stretch only has appeal to lower density carriers if stretched enough to have: 1. A321 wing 2. Two ACTs. I think that makes the niche a bit small. Too many airlines would just upsize to the A321. This is chasing too small of a Delta in market. The A320 will keep sellin...Jump to post

The 737-9 is not selling because of the 737-10. So making a A320.5 seems like a bad idea. That would make the 737-7.5 and 737-9.5 "bad ideas" too.

If an A320neo plus is just going to take away orders from the more expensive A321neo when Airbus tries to upsell an airline, then I don’t see how a business case would support such an effort.

Here is some basic knowledge that we all need to know. To stretch or shrink a fuselage length, you have to look at the size/width of the frames (aka windows part). A320's family and A330's family width are around 21". So, you need to stretch it by those rules. A320 is certified to carry 189 se...Jump to post

The C-17 eats the semi unprepared run way, preventing further utilization. Because of its mass. That's why the USAF avoids that when possible. The aircraft gets easily damaged and you want flight hours down/ used when neccesary only.
