Abstract:
The Federal Aviation Administration (FAA) has conducted numerous flight tests of small propeller-driven aircraft in support of developing aircraft noise regulations. Those test typically measured ground-level noise resulting from high power/high RPM aircraft operation. However, there is also interest, at the opposite end of the power/RPM spectrum, in examining the aural detectability of a given aircraft operating at minimal flight conditions of low power and low RPM. Such information on "how quiet and aircraft can operate" is of interest to aircraft operators who may routinely and intensively operate small aircraft over noise-sensitive communities. At the request of the Federal Bureau of Investigation (FBI), the FAA in cooperation with the Department of Transportation's, Transportation Systems Center (TSC), the Department of the Navy, and the FBI's Aviation and Special Operations Unit conducted a flight test to characterize noise emissions from selected aircraft operating at minimal flight conditions. This report presents results from the flight test.
