Fri 26 Sept 2008 – Boeing has so far signed up ten airlines for its new 777 Performance Improvement Package (PIP), scheduled for an April 2009 introduction into service. These airlines have combined 777 fleets totalling 170 aircraft and Boeing claims that the resulting one percent fuel efficiency gain will eliminate over 1,360 tonnes of CO2 emissions per airplane per year and reduce annual fuel spending per aircraft by about $200,000, assuming crude oil prices at $100 per barrel.
Key elements of the package include redesigned low-profile wing vortex generators, the addition of drooped ailerons and an improved RAM air system. Boeing is expecting the package to be certified by the US Federal Aviation Administration in early 2009.
The upgrade package is focused on the -200, -200ER and -300 models, of which there are over 500 aircraft in service. The newer models have the upgrade incorporated during factory production.
Airlines which have committed to the package include Continental, Air New Zealand, Delta, El Al, Austrian, Air France and KLM.
The latest to adopt the PIP solution is British Airways, which will install the package on its 42-strong 777 fleet. “Any cost-effective measures to improve fuel efficiency and reduce carbon emissions are to be welcomed and we’re pleased to be working with Boeing on this initiative,” said Robert Boyle, BA’s Commercial Director.
