RE: KCA Site Inspection (8)Once we start counting with the acoustical counter (AC), we will want to
document as many visible operations as we can. I’m not sure how the AC
would count the observations you witnessed. I believe the AC will count
an operation for each acoustical reading it records that exceeds a
certain dB threshold. We will have to explore the settings of the AC to
see if there is a method to get the instrument to record multiple
operations of this type. This may be one of the areas that we need to
supplement with additional information. One idea is to request that the
helicopter operators document these operations. I am assuming that
these type of touch and goes are performed by based aircraft?

Jeff:
The gate code is 12280, use all five figures. The gate opens at 8 AM
and closes at 5 PM on the weekdays. It is closed on all weekends. Jane
and I were at the airport for a meeting today and we watched a
helicopter doing touch and goes from the middle of the runway. We
counted six operations in five minutes and I wondered how we could get
those six operations counted with the counters at both ends of the
runway. Any ideas how we can cover all this.

Fred,
I would like to scout out suitable locations for the acoustical counters
and cameras at the airport. Do I have your permission to access the
airport? Is the gate code 1228?
Thanks
