Singapore Airlines Flight

Welcome aboard ASPIRE's fifth demonstration flight and first Multi Sector coordination under the ASPIRE program, the Singapore Airlines flight from Los Angeles to Singapore via Tokyo. Flight SQ11 a Boeing 747-400 departed Los Angeles International Airport on Jan. 31 and stopped in Tokyo before arriving in Singapore's Changi Airport early Tuesday.

This flight demonstrated the savings achievable by applying ASPIRE best practice procedures across all phases of flight. The flight was unique to the demonstration program as it had the added complexity of a planned stop in Tokyo.

Pre departure the 747 underwent an airframe wash and polish including engine wash, tailored water uplift and just in time fuel loading. At the departure phase, priority clearance was given for taxiing and departure with unimpeded take-off without restrictions on speed or aircraft level.

User Preferred Route and Dynamic Airborne Reroute Procedures were employed during the cruising phase to allow the pilot to capitalize on prevailing wind patterns to alter the aircraft's flight path to shorten its flight time and achieve greater flight efficiency. In addition, Performance Based Navigation (PBN) procedures such as a reduction in the lateral and longitudinal flight separation were employed, allowing the aircraft to use preferred flight paths and levels.

Efficient approach, turnaround ground procedures and departure were coordinated at Narita International to ensure the flight objectives were achieved.

Finally, at the arrival phase into Singapore, the Optimised Profile Descent technique was used to allow the aircraft to fly with engines set at idle in a continuous descent approach to land at Changi Airport. The aircraft was also assigned the shortest possible route from the runway to the parking bay.

The ASPIRE group has published that the multi-sector demonstration flight from Los Angeles to Singapore via Tokyo conducted by Singapore Airlines saved 10,686kg of fuel and cut carbon emissions by 33,769kg compared to normal practice, as well as achieving a reduction in flight time of 33 minutes.
