As an AOPA Airport Support Network volunteer, noise is a HUGE issue. The problem with aircraft noise is, I think, twofold. One, it comes from an unusual direction (overhead)which is probably hard-wired in the human nervous system as a "panic, panic, danger in the trees" response. Two, and perhaps more important, aircraft noise is intermittent. Folks can get used to ungodly noise levels IF they are consistent. there is also a fair bit of irrational hatred of the unknown; usually these complaints come along with the usual stereotype of the 'rich boy's toys'; just spend some time at your local town meeting... I even heard folks complaining about the noise from a local glider port (winch launch only); i.e., no matter of noise abatment effort, silencers, etc. could beat that. Just seeing people enjoying themselves can trigger rather interesting responses from some people; plus don't forget the folks who hope for the airport closure jackpot, increasing the value of their property (bought at discount rate since near an airport), making it possible for them to buy something better *elsewhere*... i.e., noise is only at tiny part of the issue. --Sylvain |

Reducing this and/or RPM (if CS
prop) can lead to detonation. Hold it! While you are absolutely right wrt throttle reduction, a moderate RPM reduction (e.g. to 2500 for noise reduction) is totally harmless. -- Thomas Borchert (EDDH) |

While you are absolutely right wrt throttle reduction, a : moderate RPM reduction (e.g. to 2500 for noise reduction) is totally : harmless. I'm sure that's true... just wanted to point out that modifications of the procedures in POH's (in particular partial power TO) can have unobvious but potentially bad consequences. Changing from 2700-2500 shouldn't cause engine troubles, and can reduce noise by a lot. As always, YMMV. -Cory -- ************************************************** *********************** * The prime directive of Linux: * * - learn what you don't know, * * - teach what you do. * * (Just my 20 USm$) * ************************************************** *********************** |
