Sikorsky Aerospace Services announced Feb. 18 plans to equip Sikorsky’s modernized S-61Tô helicopter with a suite of advanced avionics provided by S-TEC Corporation/Cobham Commercial Systems of Mineral Wells, Texas.
In early 2010, the U.S. Department of State entered into an indefinite delivery-indefinite quantity agreement to purchase up to 110 modernized S-61 helicopters for passengers and cargo transport missions worldwide. SAS is the aftermarket business of Sikorsky Aircraft Corporation, a subsidiary of United Technologies Corporation.
“Sikorsky’s S-61 helicopter has a 50-year legacy of reliably performing missions for the U.S. and foreign allied militaries. With its rugged endurance, spaciousness, and lift capabilities, the modernized S-61 aircraft can be outfitted to meet a wide variety of requirements. It provides superior value for a mid-size multi-mission helicopter,” said John Johnson, director, Commercial Customer Support and S-61 Programs. “We are pleased to work with Cobham, which has a solid reputation for innovation and system performance in harsh conditions.”
Decommissioned legacy S-61 aircraft are being converted into a modernized S-61T fleet that incorporate a full array of system upgrades for enhanced mission performance. The IDIQ serves as a contracting vehicle for any U.S. Government agency to purchase the modernized S-61T variant. The integrated avionics package features large-format synthetic vision flight displays, advanced flight management capability, integrated Engine Indication and Crew Alerting System, dual digital audio/radio control display units, dual VHF navigation, and communication radios.
“Cobham Commercial Systems is excited to be part of Sikorsky’s modernization of the S-61 helicopter” said Roger J. Smith, general manager, Cobham Commercial Systems, Mineral Wells. “We are proud to have been selected to enhance the mission performance of Sikorsky’s S-61T aircraft with Cobham’s intuitive 21st century cockpit.”
Cobham’s advanced avionics suite also includes an automatic direction finding system, a distance measuring system, an integrated digital audio/radio management system incorporating aft-cabin audio control. With integration of navigation, communications and warning systems that provide real-time information, Cobham’s avionics suite reduces pilot workload, enhances safety, and improves situational awareness. The modernized S-61T aircraft also offers its operators superior performance at a reasonable purchase price, with efficient operating costs and intrinsic resale value.
