February 2 – Singapore is the latest partner in the Asia and Pacific Initiative to Reduce Emissions (ASPIRE), which is designed to make aircraft operations in the region more efficient in order to reduce fuel burn and the emission of greenhouse gases.
Singapore joins the FAA, Airservices Australia, Airways New Zealand and Japan as partners to ASPIRE, which began in February 2008. The goals of the partnership include identifying and sharing procedures that produce environmental benefits, quantifying green enhancements in the region over the last decade, and establishing fuel and emissions baselines for current operations, along with future performance benchmarks.
Yesterday’s signing of the ASPIRE joint statement by the Civil Aviation Authority of Singapore was preceded by a Singapore Airlines flight from Los Angeles to Singapore Changi Airport via Tokyo Narita International Airport. That flight used the most efficient, advanced technologies and procedures to save time and fuel burn, including a no-delay departure, a new procedure called User Preferred Routing that allows aircraft to take advantage of optimum winds, and an Optimized Profile Descent into Changi that brought the aircraft from cruising altitude to the ground with greater efficiency.
Four previous flights have served as ASPIRE demonstrations. A Japan Airlines flight from Honolulu to Osaka last October used procedures such as just-in-time fueling, preferred routes over the ocean, optimized speed and altitude and a tailored-arrival approach to the destination airport. An Air New Zealand 777 flying from Auckland to San Francisco last September saved 7,700 pounds of fuel and 27,700 pounds of carbon dioxide. A Qantas A380 flying from Los Angeles to Melbourne last October saved 19,600 pounds of fuel and 61,700 pounds of carbon dioxide. And a United 747 flying from Sydney to San Francisco last November saved 10,500 pounds of fuel and 33,100 pounds of carbon dioxide.
