Colorado Springs (COS) Class C Airspace
near Meadow Lake Airport (00V)

Background

In preparation for a newsletter article, John Scott did some research into the boundary of the Class C airspace during March, 2007. In general, the pictures taken using the Google Satellite overlay (the one with the cumulus clouds) were prepared like this:

• Open SeeYou and get the Lat/Long coordinates of the corners of the notch to 4 decimal digits in decimal degrees. One place to get this info is the government published US Air Space Data. (This info is not very accurate, see below.)
• Open Google Earth and plot the three corners (push pins in picture) using the above Lat/Long info.
• Do a Screen Grab of the area of interest.
• Using a Photo Editor, draw lines between the plotted corners and approximation of the arc to the south east and northwest.

The net result is relatively recent overhead photos of the Meadow Lake area (less than 2 years old) and good information on the boundaries of the Class C airspace.

Below in the context of the first image, find information about the negotiation for the position of the cutout and how John determined the ends of the cutout where the 10nm radii continue.

Photos and boundary data

Please examine each of the photos below and the notes written against them. This will help you avoid erroneously entering the Class C airspace adjacent to Meadow Lake's "cutout". We suggest making your browser window as large as possible to best view the images.

The west boundary is Meridian Road (north-south), and the south boundary is Garrett Road (east-west). Recently, Lew suggested that John Scott to determine the location of the 10 NM arc from the center of COS. John put the center on the Volkslogger and drove to the appropriate points to determine the data. The NW corner 10 nm distant is at the corner of Meridian Road and Woodmen Hills Road (Judge Orr Road extended). The coordinates are 38.9951N 104.6078W. The SE corner 10 nm distant is not on a road, it's east of the end of Garrett Road at coordinates 38.9109N 104.5363W.
