THE ENVIRONMENTAL NOISE IMPACT OF LIGHT AIRCRAFT: A METHOD FOR COMPARING DIFFERENT LIGHT AIRCRAFT TYPES

摘要

The effects of operational patterns, hours of operation, weekend flying during the summer months, irregular flight patterns, a larger number of circuit paths, slow flying speeds resulting in lower noise levels all contribute to the annoyance of light aircraft. With correct management of these non-acoustic factors, the annoyance element of the aircraft can be reduced. Design modification to existing aircraft such as increasing the exhaust attenuation and increasing the number of propeller blades can also assist. With the procurement of new aircraft, selection of a quieter aircraft is also important.
