Saft’s ULM (Ultra Low Maintenance) nickel-based batteries are now the tech-nology of choice for commercial aircraft where they support a range of functions, including providing safe and reliable power to start the APU (Auxiliary Power Unit) as well as emergency backup for critical systems. For OEMs, they offer the ideal combina-tion of high performance and low weight. While for opera-tors the ULM design ensures extended maintenance intervals that enable significant reductions in the total cost of ownership (TCO).
Our batteries are installed on some 1,300 aircraft and have clocked up over 30 million flight hours. ATR will further extend this rela-tionship by upgrading to Saft’s new genera-tion ULM batteries for all its ATR 42 and 72 aircraft - between 80 to 100 aircraft a year.
Each aircraft will be equipped with two 24 volt batteries – a 44 Ah main battery and a 17 Ah emergency battery. The Saft batteries fitted since the aircraft first entered service have delivered exceptional performance and a long service life of around eight years. With the upgrade to ULM, ATR 42 and 72 fleet operators will be able to reduce their maintenance costs by at least a dollar for each flight hour while saving more than one kilogram of weight compared with the existing batteries.
ATR is a French-Italian aircraft manufacturer founded in 1981 as an equal partnership between Airbus and Leonardo. It is the world leader for regional aircraft in the below 90 seats category and the company has equipped the fleets of around 200 airlines in 100 countries.
