§ 12.88.530 — Determination of noise level from manufacturer's data

12.88.530 Determination of noise level from manufacturer's data.

In the event a model of aircraft has not been measured in EPNdB for its take-off noise level by the Federal Aviation Administration, or such aircraft is not listed in the advisory circular, and the airport director has reasonable doubt that such aircraft will comply with the noise level standard specified in Section 12.88.520 of this chapter, then the owner or operator of such aircraft, at the request of the airport director, shall submit to the airport director such technical information concerning noise data on the aircraft as is available from the aircraft manufacturer or other reliable sources. Such data shall be used by the airport director to determine the EPNdB noise level of such model or aircraft at take-off. If noise data has been furnished in dBA (A-weighted decibels), the airport director shall convert such dBA (A-weighted decibels) noise data to the estimated EPNdB noise level. (Prior code § 4.04.103)
