Honeywell, Safran Create Joint Venture Targeting Fuel Consumption And Emissions During Ground Ops

A U.S. and a French company have signed a memorandum of understanding (MoU) to create a joint venture company to deliver an innovative new electric green taxiing system for new and existing aircraft. 

Honeywell and French aerospace company Safran say the new taxiing system will significantly improve airline operational efficiency and provide environmental benefits by slashing the carbon and other emissions created during runway taxi operations. They expect it to be installed on new aircraft and retrofitted on to existing planes, beginning in 2016.

Taxiing burns a significant amount of fuel. Current industry analysis indicates that the world's short-haul aircraft consume 5 million tons of fuel per year during taxi operations.  The new electric green taxiing system offered by the Honeywell-Safran joint venture company is expected to save up to 4% of the total fuel consumption while providing green benefits that significantly reduce the carbon and other emissions produced by taxiing at ground level.

Honeywell and Safran plan to leverage the plane's Auxiliary Power Unit (APU) generator to power electrical motors in the aircraft's main wheels without using main engines during aircraft ground operations, thereby cutting costs, emissions and reliance on fossil fuels.

"When it comes to solving big, weighty challenges for our customers, Honeywell and Safran have unmatched track records for innovation and execution.  Today, the cost of fuel -- and the related cost of carbon emissions -- are right at the top of the list of the biggest concerns for any airline," said Tim Mahoney, president and chief executive officer of Honeywell Aerospace.  "By using the new electric green taxiing system to provide the power needed for ground-level maneuvering, Honeywell and Safran can save our airline customers several hundred thousand dollars per aircraft per year."

The companies say the new partnership capitalizes on their complementary product strengths – Honeywell's auxiliary power experience and Safran's landing gear systems.  Both companies will contribute expertise in electric power, mechanical systems and systems integration. "This partnership provides Safran and Honeywell a unique opportunity to combine our individual experience and expertise for the greater benefit of the airlines and the passengers they serve," said Jean Paul Herteman, Safran's chairman and chief executive officer. "We're excited to be working on this innovative partnership that capitalizes on our companies' individual strengths to drive performance for the airlines."

Aircraft equipped with this new electric green taxiing system should be able to "pushback and go" more quickly as well thus reducing gate and tarmac congestion, improving on time departure performance and saving valuable time on the ground. Fuel savings are not the only operational cost this aircraft electric green taxiing system will address. The system will eliminate the need for tugging and associated equipment costs, and it reduces both brake wear and taxes based on carbon emissions. 

These costs are especially problematic for airlines with high percentages of short-haul operations because ground taxiing is a greater percentage of total aircraft use. That makes airline profit margins for short-haul aircraft more sensitive to these expenses. Fuel-saving technology such as this electric green taxiing system can significantly improve the airline operator's bottom line. Honeywell and Safran intend to focus their joint venture on narrow-body-sized aircraft, which are more likely to be used for short-range flights.

The aircraft electric green taxiing system works by using the aircraft's APU to provide power to specialized motors near the main landing gear wheels.  Unique power electronics and system controllers allow the pilot to control the speed, brakes and direction of the aircraft throughout ground transportation.
