A comprehensive sea-level-static test cell data collection and evaluation effort to review operational characteristics of off-the-shelf carburetor ice detectionwarning devices for general aviation piston engine aircraft during operation on aviation grade fuel and automotive grade fuel. Presented herein are results, observations and conclusions drawn from over 250 hours of test cell engine operation on 100LL aviation grade fuel, unleaded premium and unleaded regular grade automotive fuel. Sea-level-static test cell engine operations were conducted utilizing a Teledyne Continental Motors 0-200A engine and a Cessna 150 fuel system to review engine operational characteristics of 100LL aviation grade fuel and various blends of automotive grade fuel as well as carburetor ice detectorswarning devices sensitivityeffectiveness during actual carburetor icing. The primary purpose of test cell engine operation was to observe real-time carburetor icing characteristics associated with possible automotive grade fuel utilization by piston-powered light general aviation aircraft. In fulfillment of this task, baseline engine operations were established with 100LL aviation grade fuel followed by various blend of automotive grade fuel prior to imposing carburetor icing conditions and assessing operational characteristics.
