Emirates Airline to Trial Environmental Program on Inaugural Dubai-San Francisco Flight
11 December 2008
Emirates Airline, which has one of the world’s youngest fleets, will trial a new environmental program on the airline’s first flight from Dubai to San Francisco. Emirates is working closely with government agencies in Dubai, Russia, Canada and the United States to plot the most environmentally-sophisticated trip possible to save fuel and carbon emissions on the 16-hour non-stop service.
The airline will use the new Boeing 777-200LR to service the San Francisco-Dubai route. To ensure a more fuel-efficient route, the flight will utilize new corridors of Russian airspace—this special accommodation followed negotiations and was thanks to the support of the Russian Government.
The flight will demonstrate multiple fuel and emission-saving measures including:
The new 777-200LR will be specially washed beforehand to minimize drag;
The aircraft will use electrical power on the ground in Dubai rather than running its auxiliary power unit;
Dubai Air Traffic Control will give the aircraft priority clearance for both taxiing and departure;
A pre-planned priority departure route out of Dubai will provide an unimpeded climb through to cruise altitude, allowing the aircraft to reach its optimum cruise altitude as quickly and efficiently as possible;
Recent Emirates negotiations with the Russian Government will allow for a preferred route over Russian and Canadian airspace for the most efficient path, taking into account prevailing winds and the aircraft’s weight;
Real time updates of current weather and wind conditions to allow the flight crew to modify their flight path on route;
The aircraft will track close to the North Pole following extensive work by Emirates and aircraft manufacturers to open this new routing;
Flexible routings will be pursued over Canadian airspace;
The FAA and San Francisco Air Traffic Control will seek to offer optimal routings for arrival and if possible a continuous descent approach to minimize fuel burn;
The aircraft will use minimal thrust on landing and single-engine taxi to its gate; and
All on board glass, newspapers, aluminium and paper will be collected for recycling.
Sounds interesting, I wonder how much fuel they expect to save? Post a followup!

Ben:
The Boeing 777-200LR is a high cruising speed (900 Km/hr or about 557/miles/hr), very long range (17 000 Km or about 9000 NM) aircraft and one of the lowest fuel consumption (6.1 gals/mile) in its category.
On a 16-hour flight at a cruising speed of about 500 NM/hr it would consume about 48000 gallons of fuel and land in San Francisco with minimum fuel reserve unless it benefits from good tail winds and/or extra fuel tanks.
The Boeing 777-200LR would have a very difficult time to fly Dubai/San Francisco direct via other than North Pole route unless it was equipped with extra fuel tanks.
You can assume that the total fuel saving is up to (3h x 500 NM x 6.1 gals) = 9150 US gallons +/- 3000 gals depending on winds and the non-direct route used for comparison.
The direct return flight (using the same route) would meet frequent head winds (going North) and could be more difficult.
