Honeywell and Safran have signed a Memorandum of Understanding (MOU) with GoAir for the carrier to support the development of the two OEMs’ joint venture EGTS electric taxiing system.
EGTS uses electric motors on the main landing gear to enable the aircraft to push back autonomously and taxi without using its main engines to improve operational efficiency and reduce emissions. This MoU follows an agreement with Airbus last December to evaluate EGTS as an option for the company’s A320 family.
“At GoAir, we are constantly looking for innovative ways to lower costs for our passengers while improving their flying experience at the same time,” remarked Giorgio De Roni, CEO, GoAir. “This agreement allows us to actively participate in the system’s development – a technology that we believe has the potential to not only save fuel and reduce costs, but also improve aircraft turnaround times and lower noise and emissions in the airport environment.”
Under the agreement, GoAir will provide data on its taxiing operations to Honeywell and Safran to assist in maturing the system and to define the precise fuel and other operational benefits it would see by using the technology across its fleet. The agreement will also see GoAir assist in establishing the airline standard operational procedures (SOPs) for aircraft equipped with the system.
“Where EGTS comes into its own is in supporting high-volume, fast-turnaround, short-haul movements, where aircraft spend a large proportion of the day on the tarmac taxiing,” explained Brian Wenig, vice-president EGTS program, Honeywell Aerospace. “As the only electric taxiing system to receive support from a major OEM to date, EGTS represents an exciting, cost-effective technology for airlines to lower their fuel burn and save money.”
Since the technology’s first operation on board the joint venture’s A320 test aircraft last April, EGTS has logged more than 200 km of rolling tests, including various load configurations and runway conditions, complex manoeuvres such as pushback, tight turns and U-turns, and varying specifications of acceleration and speed up to maximum takeoff weight.
“EGTS has a significant benefit over other systems in that it has a main-gear-based electric taxiing design,” noted Olivier Savin, vice-president EGTS program, Safran. “Consequently, EGTS is the only onboard system currently in development that can generate enough traction to mitigate the use of engines during taxiing in all weather conditions and at all airports,” he claimed.
