Delivering a 14,000km flight in the shortest time

Emirates to use flexible routes and take advantage of tailwinds to achieve flight efficiency

Emirates Airline’s first non-stop service between Auckland and Dubai will be one of the longest air routes in the world by distance, but with the assistance of clever technology and good planning, passengers will get to their destination in the shortest possible time.

Emirates will be using flexible routes, which can vary by day, taking advantage of tail winds and avoiding head winds to reduce the time in the air.

This proven technology, combined with the elimination of an en-route stop in Australia, could shorten the time to Auckland by up to three hours. This is not only good news for passengers, but will also result in considerably increased fuel economies – an environmental focus for Emirates.

The airline starts its first non-stop service from Dubai to Auckland on 1 March 2016, bringing many of Emirates’ 39 European destinations, as well as 38 cities in Africa and the Gulf within just a one-stop connection in Dubai.

The new non-stop service will be operated by a Boeing 777-200LR and should typically take just under 16 hours from Dubai to New Zealand and 17 hours, 15 minutes in the other direction.

“Emirates continues to invest in innovative technologies, and we utilise best practices in optimising our flight planning systems, finding the best routes that take into consideration weather and current conditions to ensure we save time, fuel and emissions, while never compromising on the safety and comfort of our passengers and crew,” said Geoff Hounsell, Emirates’ VP Flight Operations Support Services and Air Traffic Management.

“Preparing for a new 14,000km (7,600 nautical miles) flight takes an enormous amount of planning. With the work being done across all our divisions and with our partners, we look forward to delivering technical best practices within flight and route operations, and ultimately, a great passenger experience for our upcoming direct flight launch to Auckland,” he said.

New flexible route options have been a focus for the airline and Airservices Australia and Airways New Zealand have been key partners.

The majority of the Boeing 777-200LR flight will be in Australian-managed airspace, where Emirates has worked with Airservices Australia for the past decade to optimise routes, utilising the technology which will be applied on the direct Auckland route.

“The organised track system – AUSOTS – is well-proven and extending that programme so that it is specific to the Auckland–Dubai route will have significant benefits, without impacting the operations of other aircraft going to Australia,” said Geoff Hounsell.

Airservices Australia safely controls 11 per cent of the world’s airspace.

“A number of our air traffic control and environmental specialists have worked with Emirates’ flight planning team to help find them the most optimal east and west-bound routes which will link the flight into our existing Flex Tracks and user preferred route (UPR) zones.” said Executive General Manager, Air Traffic Control, Mr Greg Hood.

“Airservices Flex Track and UPRs will help Emirates realise significant savings in fuel, reduce its greenhouse gas emissions and reduce the flight time with seasonal and daily variations based on the positioning of jet stream winds,” said Mr Hood.

Airways New Zealand chief operating officer Pauline Lamb says air traffic controllers are looking forward to welcoming the Emirates Boeing 777-200LR into the region. Airways manages more than 1.2 million air traffic movements per year within 30 million square kilometres of airspace across New Zealand, the Pacific Ocean and Tasman Sea.

Airways’ controllers will safely guide the far reaching Boeing 777-200LR through the first and last hours of these ultra-long range flights, ensuring these aircraft get the best and most efficient service possible.

“Emirates will benefit from Airways’ capability to offer new fuel-efficient arrival routes into Auckland and a high degree of flexibility using very efficient ‘user-preferred routing’, including the ability to review and change flight paths during the flight. This will allow Emirates to choose the most fuel and cost efficient routes every time,” said Ms Lamb.

The Boeing 777-200LR has the same wing size as its Boeing 777-300ER cousin but can fly up to a range of 8,400 nautical miles with full passenger load of 266 – eight in First Class, 42 in Business Class, and 216 in Economy Class.

The non-stop flight will have a complement of 13 cabin crew and four pilots, allowing for rest periods.

Emirates has a fleet of 249 aircraft, including 74 double-decker Airbus A380s and 155 Boeing 777s, among them 10 Boeing 777-200LRs.

Background points:

• The optimum route to reduce airtime and maximise fuel savings is determined by a number of factors.
• Other aircraft movements departing at the same time

• The different configuration of aircraft, or different payload
• Weather conditions, particularly prevailing winds / strong winds
• Planning for individual flights commences between 10-12 hours prior to departure and is revised closer to departure.
• Two hours prior to flight departure, the most optimised route is chosen, but can still be updated during the flight.
• At all times there is a contingency flight plan, so if an unexpected event arises during the flight, there is an alternative routing available.
• Passenger and crew experience
• Fastest route to Dubai which connects directly with 39 European destinations and 38 cities in Africa and the Gulf
• With the non-stop flight to Dubai, passengers can enjoy their flight experience without the interruption of an airport transit stop
• Crew welfare is of utmost importance and new ways of working are constantly being reviewed and optimised for long haul flights for the benefit of crew and passengers.
