Boeing on Thursday said it plans to add a 787-10 “Explorer” to its ecoDemonstrator program this year while it moves ahead with its assessment of 19 technologies under study with the program’s 777-200ER. The first ecoDemonstrator Explorer will conduct flight tests in June from Seattle to Tokyo, Singapore, and Bangkok to demonstrate how coordinating navigation across global airspace jurisdictions can improve operational efficiency and reduce fuel use and emissions by up to 10 percent.
The plan calls for Boeing and air navigation service providers (ANSPs) in the U.S., Japan, Singapore, and Thailand to collectively sequence the airplane's routes to achieve the optimal flight path across multiple regions, taking account of conditions such as weather, air traffic, and airspace closures. The airplane will fly on the highest available blend of sustainable aviation fuel (SAF) at each location.
