Pattern Noise Limits
What are the latest contest Pattern noise rules and how are they measured. We are instituting a noise abatement program at our flying field and need to know how others are doing it.
Best Regards,

RE: Pattern Noise Limits
Go to the back of the current AMA rule book. It shows the and gives all the specifics to the proper way to read the noise levels. It is in the Addendum section and is the very last page on the current book. The setup is shown there and discussed.
AMA standards are 96db(A) on pavement and 94db(A) on grass. These are measured in the setup shown in the book.
