L'Aspire d'hier qui a gonflé d'un jour sur l'autre !
http://www.aspireaviation.com/2012/04/09/boeing-continues-to-optimise-737-max/
A prendre avec des pincettes aussi !
Le PR de Boeing fait des dégâts , ou il ont peut être embauché tous les analystes Américains ... hum !
Bien, dans 18 mois on saura avec certitude où va le A320 NEO, il volera avec des GTF sous l'aile ... mais j'ai l'impression que pour le 737 MAX, on n'est pas prêt de voir l'ombre d'une vérité, tout est biaisé !
De toute façon, plus ça fait de bruit à Seattle, ben, ça indique juste une forte recherche de solutions ... celà pour une trés simple raison ... le compte n'y est pas du tout pour le moment !Des indications de range et de poids (Extrait) ... pour ce que ça vaut ... hum !
Bon courage !

According to Aspire Aviation‘s multiple sources at Boeing, the 737 MAX 8 and MAX 9 will see a 3,175 kilogrammes (7,000 lbs) increase in maximum take-off weight (MTOW) from the winglet-equipped 737-800′s 79 tonnes (174,200 lbs) to MAX 8′s 82.2 tonnes (181,200 lbs) and from winglet-equipped 737-900ER’s 85.1 tonnes (187,700 lbs) to MAX 9′s 88.3 tonnes (194,700 lbs). The smaller MAX 7 sibling will see a 2,268 kg (5,000 lbs) increase in its MTOW from winglet-equipped 737-700′s 69.4 tonnes (153,000 lbs) to 71.7 tonnes (158,000 lbs).
In comparison, Airbus said the maximum take-off weight (MTOW) of the A320neo (new engine option) will increase by 1 tonne (2,205 lbs) to 79 tonnes (174,165 lbs) from A320 weight variant WV015′s 78 tonnes (171,961 lbs), the A320 weight variant featuring the highest MTOW.
In terms of range, the range of the 737 MAX 8 will be 6,426 km (3,470 nm), an increase of 405 nm with 162 passengers. The MAX 7 and MAX 9′s ranges will be 3,800 nm with 126 passengers and 3,430 nm with 180 passengers, respectively.
The existing CFM56-5B-powered A320 has a range of roughly 3,000 nm with 150 passengers at a payload of around 13,800 kg and Airbus has said the new engine option will either add 950 km (510 nm) to range, or 2 tonnes (4,400 lbs) in additional payload. The CFM56-5B-powered A319 has a range of roughly 3,200 nm with 124 passengers at a payload of around 11,000 kg. The CFM56-5B-powered A321 has a range of roughly 3,000 nm with 185 passengers at a payload of around 17,000 kg, according to payload/range graphics on Airbus’ aircraft characteristics documents.
On an apple-to-apple basis with the same payload on both 737 MAX 8 and A320neo at 13,800 kg and all increase in payload is used to boost range, the 737 MAX 8 will have the 737-800′s range at a payload of 13,800 kg of approximately 3,240 nautical miles (nm), plus the addition of 405 nm due to the re-engining. Simply put, the 737 MAX 8 will have a range of approximately 3,645 nm, more than the A320neo’s approximately 3,510 nm.
Similarly using the aforementioned Airbus document and Boeing’s chart, the A321neo will have a range of approximately 3,510 nm whereas the 737 MAX 9 will have a range of 3,430 nm. The A319neo will have a range of approximately 3,710 nm versus the 737 MAX 7′s range of 3,800 nm.
Therefore, the 737 MAX 7 and MAX 8 are slightly better in range than the A319neo and A320neo, respectively, whereas the 737 MAX 9 will be slightly inferior to the A321neo in range.
