So Airbus are considering the AFE-21XLR as the ultimate evolution of the current AFE-21LR. Now it will feature a slightly larger fuel tank which will allow it to fly even further down its counterpart. Now it's not exactly clear whether adding a larger fuel tank will hinder the seating capacity of the plane or whether it will have an impact on the maximum takeoff way. But one thing is for sure, the Airbus are saying that it could be the answer for the guppin' middle of the market as Boeing are taking their time to evaluate, study and hopefully launch the plane by 2025. But there are some people in industry who are thinking what is the point of the plane. Now Airbus have said themselves that it will be primarily for the North American carriers. Are many people are saying that the LR and the XLR are only cheap options for the airlines until the 797 comes into the market. Well the 797 has two variants, also known as the NMA-6X and NMA-7X. Now the 6X would aim to carry up to 225 passengers with a distance of 5,000 nautical miles, and the 7X carrying up to 265 passengers with a distance of 4,500 miles. Now the XLR will be able to carry up to 245 passengers give or take with 206 in a two class configuration on 4,600 nautical mile missions. Now if Boeing does decide to go ahead with their two variants, the 6 and the 7, then the XLR will carry 25 more passengers than the 6X, although it will fly 500 miles less. However the 7X will carry 15 more passengers and travel as the same distance as the XLR give or take. So if we take all of these numbers into consideration, then it's not really surprising that Airbus are considering a longer range variant of its long range A321. But we should bear one thing in mind. Airlines have plenty of experience with a single aisle, middle of the market aircraft by using the 757. Although it's a short and narrow body with acceptable range, it could work on some long skinny routes, but there hasn't been much infusion as I'm forward nor has it really materialized into something tangible because the way of the additional fuel will come out cost of fuel receipts. Now although there isn't concrete evidence as of yet to support this claim, we do know however that Boeing will compromise on optimal efficiency, because the middle of the market missions can't be supported or be done by anything that is larger than the conventional size of the 757. The 767 for example is simply too big and is too heavy, and it's not really interesting or opportunistic. In the case of NMA however, the 7A breath shape will be a big winner. Featuring a cross section of around 15 square meters and the next generation engine, the 797 could be the ultimate answer to fly the niche market perfectly. But for now it'll be interesting to see where the Airbus goes through the XLR variant for the successful A321 program. If Boeing does indeed announce and release the NMA-7X, it will be longer until Airbus starts the development of the XLR to be the 797.

Or do you think that the 797 is over hyped and the job can be done with a similar plane? Let us know in the comments below.
