"Never fly the A model of anything."

Because:

Airframe Manufacturers' RULE#1

"Certify it at the factory. Test fly it in the field!"

Should give plenty to talk about at the S-92 operators conference next week!
Presumably they've booked somewhere big enough for all those people? You know, a village hall or a garden shed or something?

FAA Grants Sikorsky S-92 Full Icing Certification


Oct. 17, 2005
-

STRATFORD, Conn. The Federal Aviation Administration has certified Sikorsky Aircraft's S-92 helicopter, equipped with a new Rotor Ice Protection System (RIPS), for flight in known icing conditions. It becomes the first helicopter directly certified by the agency to the newest and most stringent all-weather flight safety standards. Sikorsky is part of United Technologies Corp. (NYSE:UTX).

Any S-92 with RIPS will now be allowed to launch in icy weather that might otherwise delay or cancel flight operations. The RIPS determines the temperature and moisture content of the surrounding environment and applies heat to the main and tail rotor blades to remove any ice buildup.

"One of the S-92's key features is its all-year, all-weather capability. Certification of RIPS adds to the S-92's reputation as the most modern and efficient aircraft in its class," said Jeffrey Pino, Sikorsky's Senior Vice President for Corporate Strategy and Commercial Programs.

The FAA granted the certification upon completion of final flight tests in Alaska in October. Those tests also included evaluations by the European Aviation Safety Agency (EASA) and by Transport Canada, the Canadian certifying agency. Sikorsky is seeking S-92 RIPS certification from both agencies.

Most of the S-92 helicopters delivered to date or ordered include RIPS. Beginning this month, Sikorsky teams will visit customers to update the previously delivered RIPS equipment and activate the system for operation now that it has received certification. Besides Sikorsky, key suppliers include the Autronics and Penny & Giles divisions of Curtiss-Wright and the Moog Corporation.

Development of the S-92 RIPS began in 1997 and included three years of aircraft testing. That testing began with ice accretion tests in the Eglin Air Force Base McKinley Climatic Hangar in Florida and dry air tests of simulated ice on the tail surfaces in 2003. In 2004 Sikorsky conducted flight-testing behind a CH-47D helicopter with special equipment that creates a cloud of ice in the air behind it. The tests ended with flights in natural icing conditions in 2004 and 2005 at sites from the northeastern United States, through Canada to Alaska.

Sikorsky also plans to incorporate similar rotor ice protection equipment on the new S-76D helicopter, which is slated to enter service in 2008.

Sven,
The FAA only knows one kind of approval, - full - based on the inability of the pilot to control the intensity.

For the guys who don't like the idea of launching into icing conditions, welcome to the 21st century. I remember when people siad that about IFR in helos.

It's not the idea that bothers me; I just won't be needing it.

Airconditioning maybe

Hi Nick,

Well done to Sikorsky! Is this an optional system or does it come as standard? Roughly how big of an effect would airframe icing have on the 92's performance in heavy icing conditions?

Woolf,

The completed system is optional, but the bigger gens and most of the heavy electrical distribution are part of the basic empty weight, the mats are embedded in the normal blade airfoil and so cause no performance loss. The weight gain to have the controller, slip ring and the like installed is not too great, less than 200 lbs, I believe.

I believe the aircraft suffers some performance loss in icing flight, since the ice is allowed to accrete somewhat before being tossed off, but that usually just drops the Cat A ceiling a bit, and the 92 has a fairly good one. I will try and hunt some specifics and post them (now that I am on the outside, no promises!)

Transport Canada Grants Sikorsky S-92 Helicopter Full Icing Certification

Transport Canada Grants Sikorsky S-92 Helicopter Full Icing Certification
Monday October 31, 11:36 am ET


STRATFORD, Conn., Oct. 31 /PRNewswire-FirstCall/ -- Transport Canada has certified Sikorsky Aircraft's S-92 helicopter, equipped with a new Rotor Ice Protection System (RIPS), for flight into known icing conditions. Transport Canada's certification comes on the heels of the Federal Aviation Administration's precedent-setting certification earlier this month. The S-92 is now certified to the newest and most stringent all-weather flight safety standards for both the United States and Canada. Sikorsky is part of United Technologies Corp. (NYSE: UTX - News).

Transport Canada certification validates the S-92 type design and authorizes its use on aircraft flying under Canadian registry. Both Transport Canada and the European Aviation Safety Agency (EASA) flew a RIPS equipped S- 92 in Alaska in October to test the new de-icing system immediately following the FAA flights.

"Icing conditions in Canada are among the most severe in the world. This makes the Transport Canada endorsement particularly meaningful," said Mick Maurer, Sikorsky Vice President of Commercial Programs. "Cougar Helicopters Limited, one of the earliest S-92 customers, was a key participant in the certification effort. Cougar's operations in St. John's, Newfoundland, are influenced much of the year by severe icing. Cougar has special expertise in these types of operations, so much so that their knowledge and experience was sought by the FAA in advance of the S-92 flight tests."

Any S-92 with the RIPS will now be allowed to launch in icy weather that might otherwise delay or cancel flight operations. The system determines the temperature and moisture content of the surrounding environment and applies heat to the main and tail rotor blades to remove any ice buildup.

Canada's 28 new H-92 maritime helicopters being built by Sikorsky, designated the CH148 Cyclone by the Canadian Forces, are naval variants of the S-92. The Cyclone will possess the same ability to fly into known icing conditions as the S-92.

Most of the S-92 helicopters delivered to date or ordered include RIPS. Beginning this month, Sikorsky teams will visit customers to activate the system for operation now that it has received certification. Besides Sikorsky, key suppliers include the Autronics and Penny & Giles divisions of Curtiss-Wright and the Moog Corporation.

Development of the S-92 flight into known icing capability began in 1997 and included three years of aircraft testing. That testing began with ice accretion tests in the Eglin Air Force Base McKinley Climatic Hangar in Florida and dry air tests of simulated ice on the tail surfaces in 2003. In 2004, Sikorsky conducted flight-testing behind a helicopter with special equipment that creates a cloud of ice. The tests concluded with flights in natural icing conditions in 2004 and 2005 at sites in the northeastern United States, Canada and Alaska.

S-92 Chosen for UK SAR

Sikorsky S-92(TM) Helicopter Selected for UK Offshore Search-and-Rescue Missions
Tuesday December 13, 9:29 am ET


STRATFORD, Conn., Dec. 13 /PRNewswire-FirstCall/ -- Sikorsky Aircraft has signed a contract to provide four S-92(TM) helicopters to CHC Helicopter Corporation to perform commercial search-and-rescue (SAR) missions for the United Kingdom Maritime and Coastguard Agency (MCA) beginning July 1, 2007. Sikorsky is part of United Technologies Corporation (NYSE: UTX - News).

Under the five-year contract with the MCA, CHC will operate its S-92 fleet around-the-clock from coastal bases in Sumburgh, and Stornoway.

This marks the first time that the S-92, the world's newest medium-lift helicopter, has been selected for a dedicated SAR mission. "The S-92's modern technology, performance, and industry-leading safety standards make it superbly equipped for SAR," said Jeffrey Pino, Sikorsky's senior vice president for corporate strategy, marketing, and commercial programs.

Company founder Igor Sikorsky was inspired to build helicopters because he believed in their life-saving capabilities. Within the past year alone Sikorsky-built helicopters rescued thousands during the aftermaths of the Asian tsunami, Hurricane Katrina, and the earthquake in Pakistan. "Sikorsky helicopters have been saving lives for more than 60 years. We are proud that CHC has selected the S-92 to build upon this legacy," Pino said.

CHC's S-92s will be equipped with duals hoists, autopilot, coupled hover capability, and the new Rotor Ice Protection System (RIPS), which meets the Federal Aviation Administration's latest and most stringent all-weather flight safety standards. RIPS allows the S-92 to launch into known icing conditions that might otherwise delay or cancel flight operations. The RIPS determines the temperature and moisture content of the surrounding environment and applies heat to the main and tail rotor blades to remove any ice buildup.

The S-92 is the first helicopter in the world certified by the European Aviation Safety Agency/ Joint Aviation Authorities (EASA/JAA) to the latest and most rigorous safety standards. The S-92 was also the first helicopter certified by the FAA to FAR Part 29 Transport Rotorcraft, Amendment 47, the latest U.S. safety regulations, which mirror the European standards.

Sikorsky Aircraft Corporation, based in Stratford, Conn., is a world leader in helicopter design, manufacturing and service. United Technologies Corporation, based in Hartford, Conn., provides a broad range of high- technology products and support services to the aerospace and building systems industries.

CHC Helicopter Corporation is the world's largest provider of helicopter services to the global offshore oil and gas industry, with aircraft operating in more than 30 countries around the world. CHC currently provides search and rescue and emergency helicopter services in Ireland, Africa, Australia and Norway.

S92 Icing Clearance

This Toad is easily confused, but I know many others will know the answer and tell me. So here goes:

The S92 is now certified by Transport Canada and the FAA (and they should know, shouldn't they?) for flight into known icing conditions when fitted with the Rotor Ice Protection System. As I understand it this protects main and tail rotor blades; plus of course there will be the usual protection for pitot static, TAS, windshield and engine/gearbox intakes.

However, isn't there a likelihood of ice accretion on the fuselage, the upper control runs up to the pitch-change horns, the aft stabiliser and any other bits that stick out? Also when your airframe is in sub-zero temperatures and you get rained on from above (yes, it can happen) you WILL ice up; you must hope to be able to escape pdq while remaining within the rotorcraft limitations. No fun.

Did I miss the point or is there some other protection means on the 92? After a lifetime of not always dodging the ice I guess I'm not easily persuaded. Seems a bit like the Emperor's clothes to me.

Toad,
You certainly didn't miss the point, the clearance is for the entire aircraft. The areas you worry about were also checked for any hazardous accretions/releases of ice, and no problems were found. Were a problem found, you would see some sort of protection on it, typically starting with some sort of shield, then maybe icephobic paint/coatings, then perhaps heating, each used in steps to attain icing approval. For the S-92, these methods weren't needed (aren't as well for the Black Hawk, which has delivered about 2,000 anti-iced helos, and for the Sea King, which as several hundred.)

You confusion is probably in not knowing the rules under which an operational approval is given. The approval is for the entire aircraft and its operations, not for a rotor system.

If you don't buy it, sorry about that, but the airliners you fly in have the exact same rules and cert methods, to the letter. When visiting Grandma, buy lots of bus tickets, Toad.
