Noise Reduction



Keep propeller tip velocity below Mach 0.5

Read Sound at the field for more information. Propeller tip velocity chart will help you meet sound level rules. Information on mufflers, and other factors affecting noise generation and propagation are included.  Electric Ducted Fan (EDF) systems must also comply with club noise level limits.  Some gliders may also require noise reduction depending on design of the system.


AMA Sound/Noise Abatement Recommendations - Noise levels in flying site lease agreements must be complied with to ensure continued use of these locations!



If you have a new or modified gas or glow engine model aircraft, please contact Steve Ashmore to set up a time to test your aricraft at the field.  If you have any questions about how to reduce noise level, Steve or other club members would be happy to help.
