Inversion layers may exist whereby icing conditions are more in evidence than lower down, so we can climb by Mike Stratman with plenty of power and suddenly experience icing in an inversion. In the East inversions can be any height in a high pressure system (clear cool day). In a low with Dennis Pagen pressure system inversions don’t usually occur, but plenty of humidity abounds so icing can be a problem.

  • EASA Safety Information Bulletin
    EASA SIB No: 2010-03 EASA Safety Information Bulletin SIB No.: 2010-03 Issued: 13 October 2010 Subject: Carburetor Icing Prevention Ref. Publications: Federal Aviation Administration (FAA) Special Airworthiness Information Bulletin (SAIB) CE-09-35 dated 30 June 2009. Applicability: All piston engines with carburetors, installed on any aircraft. Description: The FAA published the above-referenced advisory document (which is attached as pages 4 through 6 of this bulletin) to inform pilots of piston engine aeroplanes of the potential hazards associated with carburetor icing. After reviewing the available information, EASA support the recommended actions contained in FAA SAIB CE-09-35, but consider this should apply to piston-engine rotorcraft as well. Since this is a ‘generic’ subject that addresses all piston engines with carburetors, i.e. not only those of US origin, the SAIB cannot be considered as a ‘State of Design’ advisory. For that reason, EASA have decided to explicitly apply these recommendations to all piston engines with carburetors and add recommendations for carburetor icing when experienced on rotorcraft. This SIB is published to ensure that all pilots of piston engine aircraft registered in European Union Member States or associated countries, are made aware of these recommendations. Recommendations: For fixed-wing aircraft, refer to the FAA SAIB, pages 4 through 6 of this SIB. For rotorcraft, it should be considered that piston engine helicopters equipped with carburetors are as vulnerable as aeroplanes to carburetor icing in the critical conditions of temperature and relative humidity. However, the consequences of icing are potentially much more severe. In a light aeroplane, ice accretion in the intake is relatively obvious through monitoring of engine RPM (revolutions per minute), manifold pressure and general engine behaviour.

    308 Chapter 3: The Design Revolution Document 3-15(a-e) 309 INTO THE NacELLE The problem becomes easiest when there are outboard engine nacelles, for the nacelle usually provides ample space for housing the gear and gives the proper tread with the wheels located under the concenetrated loads On a high wing monoplane design with engines in the leading edge, the landing gear must be very high Because of the great height it is almost impossible to take the side loads as a cantilever, and therefore the design must be complicated by side struts to the fuselage as on the General YO-27 (see illustration) where they remain out in the air-stream when the wheel is retracted In the new Dutch built Fokker F-XX a compromise apparently has been reached by retaining the high wing and lowering the engine nacelles below the wing so that a completely retractable gear can be obtained with no side struts to the fuselage, the nacelles carrying all the load Fokker seems to have decided that the slightly increased drag of the lowered nacelles did not offset the advantages of the high wing, with its inherently less drag and greater lift as well as its absence of buffeting and better passenger vision (see page 59 and references 3, 4 and 5) How- ever, some designers have reached a compromise in another fashion, locating the nacelle in the best position with reference to the landing gear and then lowering the wing to have the engine in the leading edge Examples of this are the new Martin bomber, the Boeing bomber and the new Boeing transport, and the new Douglas

    U.S. Department of Transportation Federal Aviation Administration FAA Headquarters Aviation Education Division FEDERAL AVIATION ADMINISTRATION CURRICULUM GUIDE FOR AVIATION MAGNET SCHOOLS PROGRAMS Prepared by Dr. Mervin K. Strickler, Jr. AHT-100-1-94 ABOUT THE AUTHOR Dr. Mervin K. Strickler, Jr., a native of Pennsylvania, graduated from Clarion State University. In 1951 he received his doctorate from Stanford University with specialization in aviation higher education. During his long and distinguished career he served as Director, USAF-Civil Air Patrol Aviation Education from 1951 to 1960, and as Director of the Federal Aviation Administration's Aviation Education Program from 1960 to 1979. From 1973 to 1979, he also worked with the Commonwealth of Independent States (then Soviet Union) as the FAA's representative for scientific and technical aviation education and training for all facets of civil aviation. He continues today as an international consultant on aviation education matters to industry, government, and all levels of education. Dr. Strickler's many publications and papers are included in libraries around the world. He is frequently called upon to speak at major aviation events and is well known nationally and internationally for his expertise in aviation education. PREFACE The Federal Aviation Administration's current interests, activities, projects and programs in aviation education represent and stem from a continuation and expansion of programs and similar initiatives of its predecessor organizations. Present programs are a result of the most recent FAA Administrator's Task Force Report on Aviation Education completed in 1990. The Report identified over fifty aviation education initiatives as appropriate to support the agency's objectives.

Abstract The purpose of this study was to perform a current assessment of the frequency and severity of carburetor/induction icing in general-aviation accidents. The available literature and accident data from the National Transportation Safety Board were collected. A computer analysis of the accident data was performed. Between 65 and 90 accidents each year involve carburetor/induction system icing as a prob- able cause/factor. Under conditions conducive to carburetor/induction icing, between 50 and 70 percent of engine malfunction/failure accidents (exclusive of those due to fuel exhaustion) are due to carburetor/induction system icing.
