(www.flightglobal.com) Boeing has officially launched the package for 777-200/200ER/300 models (dubbed "Classics") with orders for 139 aircraft from "at least seven" carriers, including launch customers Air New Zealand, Continental Airlines and Delta Air Lines. Boeing also confirms that Austrian Airlines, El Al and KLM have ordered upgrades for their 777 Classics.
The combined improvement is aimed at reducing annual fuel consumption per aircraft by as much as 454,000kg (one million lb), the company says. Such savings should reduce an airline's annual spending on fuel by $300,000 per aircraft, according to Boeing estimates. Drooping the 777's outboard ailerons on both wings generates a 0.4% fuel efficiency improvement. Another 0.4% improvement comes from installing the ram air system.
