|  09  2012 AnnUAL REPORT Sikorsky’s S-92 helicopter is  used to transport workers to  and from offshore petroleum  operations, as well as for  executive transportation and  search-and-rescue missions. Our aerospace businesses continue to raise the performance bar.  Sikorsky’s S-92 helicopter, certified to the most stringent safety standards of the Federal Aviation Administration and the European  Aviation Safety Agency, enables operators to conduct critical offshore  petroleum operations and search-and-rescue missions even in severe  weather. In 2012, the FAA certified the aircraft’s newest flotation system  for its capability to perform in Sea State 6 conditions, when waves can  reach as high as 20 feet and winds as strong as 47 knots. The aircraft’s reputation for safety and robustness helped produce an order backlog  totaling $1.5 billion by year-end. Pratt & Whitney’s new PurePower GTF engine also promises to be a game changer when it enters  service. The ultra-efficient engine is expected to reduce fuel burn by up to 16 percent, nitrogen  oxide emissions by half and airport ground noise by 75 percent. Another big advantage—it is  expected to generate an annual cost savings of up to $1.5 million per aircraft over today’s best  engines in its class. The PurePower engine has been chosen to power next-generation aircraft  from Airbus, Bombardier, Embraer, Irkut and Mitsubishi Aircraft Corporation. Top performance depends on people. In 2012, more than 40,000 UTC Aerospace Systems  employees demonstrated a remarkable ability to embrace change and accelerate performance.  Ten months after the announcement of the largest acquisition in aerospace history, the  employees of Goodrich and Hamilton Sundstrand came together as one integrated company.  Intensive planning, coordination and teamwork resulted in seamless customer support and the achievement of all financial commitments.  Otis and UTC Climate, Controls & Security are  committed to offering customers innovative,  high-performing products. Otis’ NCE escalator  is equipped with an energy-saving regenerative  drive, power-standby features, LED lighting  and high-efficiency lubrication. Recognized  for its world-class customer service, Otis  soon will launch eService mobile, an app that enables customers to monitor the status of their  elevators and log service calls from a mobile  device while on the go. During the year, several Carrier products achieved  breakthrough energy efficiency and industry-leading  performance, including the Evergreen 23xRv chiller with  Foxfire compression technology and the Infinity 98 gas  furnace. These products demonstrate UTC Climate, Controls & Security’s commitment to innovation.  Otis’ tradition of innovation continues with the nCE escalator.
