A350 Concept |
Airbus intends to decide whether to proceed with enhancements to the
A330 during the second half of this year, but is still reticent to
provide many details. The airframer is studying the possibility of raising the maximum
take-off weight of the A330-300 by 5t, taking it to 240t and potentially
prolonging the life of the type as it develops the A350 XWB. However, its strategy for achieving the additional capability remains
unclear, beyond indications last month that "sharklet" wing-tips could
be adapted to the larger twinjet.
Discontinuation of the A340 potentially offers a mechanism to reduce
weight, as there would be no need to maintain structural commonalities
between the two types. While the A330 would have been structurally
different as a "clean sheet" aircraft, Airbus would need to assess
whether there is room to make any economical alterations on its
production line.
Proposals
for a higher-weight A330 revive a plan to create a longer-range version
of the -300, discussed by the airframer more than a decade ago. That
plan also aimed for a 240t take-off weight, as well as higher-thrust
engines. But the A330-300's take-off weight remained at 233t until last year, when the airframer offered a 2t hike to 235t. Airbus would want to avoid any major change on the undercarriage.
While it had previously considered adopting the A340's distinctive
centre gear to reduce pavement loading, such a decision would simply add
weight - and complexity.
All three major engine manufacturers offer A330-300 power-plants.
There is no immediate evidence that Airbus is considering re-engining
the A330, a move which would essentially bring the airframer back to the
original A350 - a concept which received a tepid response from the
market when first promoted as a Boeing 787 rival. Airbus is giving little away, although it has indicated further details could be released during the Farnborough air show.
"As part of Airbus's philosophy, we are continuously looking at the
market and studying further improvements to our portfolio," said the
airframer. "Any decision on whether to proceed will happen in the second
half of 2012."
