Forgoing a fuel-filter change on a jetliner as big as the 777 may, by itself, seem to be a small step in reducing waste and helping the environment.
Yet a team of environmentally engaged employees, which has combined this small step with nine other actions, is having a big impact in making 777 flight tests and deliveries cleaner, quieter and easier on the environment.
“We wanted to reduce the environmental impact of the 777 preflight and delivery process, which includes activities such as painting and engine testing,” explained Carolyn Barnes, 777 Operations support.
The team designed ten environmental initiatives that are reducing fuel use by 300,000 gallons (1.14 million liters) and carbon dioxide output by 5.5 million pounds (2.5 million kilograms) annually on 777 deliveries, along with achieving other environmental improvements.
The environmental initiatives include
The team chose a “pilot” 777-300ER (Extended Range) to test all of the initiatives together and received permission from customer Air New Zealand to implement all the initiatives in the preflight and delivery process. Now, most of these steps are routinely implemented during all 777 deliveries with the use of chrome-free primer, a customer option.
