SJ30 Jet Excels in Airframe Icing Tests.SAN ANTONIO San Antonio (săn ăntō`nēō, əntōn`), city (1990 pop. 935,933), seat of Bexar co., S central Tex., at the source of the San Antonio River; inc. 1837. -- Sino Swearingen Aircraft Corporation Sino Swearingen Aircraft Corporation SSAC (ICAO name: SINO SWEARINGEN) is an aircraft manufacturer. Their primary product is the Swearingen SJ30-2 small business jet. The company's headquarters is in San Antonio, Texas, with additional assembly facility in the John D. (SSAC SSAC Security and Stability Advisory Committee (ICANN) SSAC Scottish Sub Aqua Club SSAC State Sports Administration of China SSAC South Suburban Action Conference SSAC Social Security Advisory Council SSAC Soil Site Assimilated Capacity ) announced today the completion of another major milestone for the SJ30 business jet. The final flight test in actual icing conditions In aviation, icing conditions are those atmospheric conditions that can lead to the formation of water ice on the surfaces of the aircraft, or as carburetor icing within the engine. Inlet icing is another engine-related danger, often occurring in jet aircraft. was completed on March 1, 2006 in Provo, Utah. This testing consists of the FAA requirement to complete a 45 minute hold in actual maximum continuous icing conditions, and was completed by Test Pilots Mark Fairchild, John Siemens, and Flight Test Engineer Schuyler Horn. On October 27th, 2005, the company announced that it had received FAA Type Certification for the SJ30, and that two tests remained before the initial delivery to a customer. The two remaining tests were for the approval for flight into known icing and the approval of the aircraft's interior. DER DER - Distinguished Encoding Rules Test Pilot John Siemens said, "The airplane performed remarkably well in the extreme icing conditions we encountered. It is also my opinion that the SJ30 performed better in the ice than any other airplane I have previously certified for flight in known icing conditions." The SJ30 is equipped with electrically heated windshields and uses engine bleed air Bleed air in gas turbine engines is compressed air taken from within the engine, after the compressor stage(s) and before the fuel is injected in the burners. While in theory bleed air could be drawn in any gas turbine engine, its usage is generally restricted to jet engines used heat to anti-ice the wings and engines. Pneumatic boots are used to de-ice the horizontal tail Noun 1. horizontal tail - the horizontal stabilizer and elevator in the tail assembly of an aircraft elevator - the airfoil on the tailplane of an aircraft that makes it ascend or descend . The approval flight involved 50 minutes of maximum continuous icing conditions and more than another hour of intermittent icing conditions, which resulted in a build up of over 4 inches of ice on unprotected areas of the aircraft. Siemens noted, "The flight characteristics and handling qualities were very good with this residual ice accumulation. In the post flight debriefing de·brief·ing n. 1. The act or process of debriefing or of being debriefed. 2. The information imparted during the process of being debriefed. Noun 1. , the flight test crew all agreed that the SJ30 is one of the safest airplanes on the market today when it comes to flying in icing conditions." Earlier in February, test pilot John Siemens and other members of the flight test crew completed artificial ice shapes testing at Roswell, NM. This testing is required to demonstrate aircraft handling characteristics, including stability, control, and stall characteristics, with simulated ice attached to the airframe, replicating what would accumulate on unprotected surfaces during flight in a 45 minute maximum continuous ice encounter. SSAC's SJ30-2 business jet is a high performance twinjet aircraft with a range of over 2,500 nautical miles and the highest cruise speed in the light jet industry of Mach .83 (560 mph). This single pilot certified jet operates at altitudes to 49,000 feet and maintains a "Sea Level Cabin" of 12 psi through 41,000 ft. SSAC is positioned to produce a family of cost-efficient, high performance, high-quality business jets.
