2003 Mather Field noise studies:
Noise complaints
The bottom line:  Do we have a noise problem, a complaint problem, neither, or both?

In December the Sacramento County Airport system reported on results of its 120-day study of use of the alternative VOR/DME approach, in addition to the standard ILS approach. A report on 250 approaches showed 54% of arrivals using the VOR/DME approach, 46% using the ILS approach.

The total number of approaches during 2003 would have been higher -- normal freighter traffic during 2003 produced about 6 arrivals per day.


Summary of complaints

4,019 noise complaints during the test period. 1,987 related to nighttime operations. El Dorado Hills accounted for 939 complaints from 140 callers. Of these, 496 complaints from 83 callers were for nighttime operations.
