# The Class B, C, and D airspace information in this file is composed of       <
# computed approximations of the arcs and lines that make up various airspace  <
# boundaries that have been derived from lists of points along those boundaries.<
# The point data has been taken from the Federal Aviation Administration       <
# National Airspace System Resource (NASR) geospatial information files,       <
# also known as shapefiles, as published by the National Flight Data Center.   <
# Errors in the computed positions of the boundaries themselves will generally <
# be less than 300 feet, although some errors might be much larger.            <
# Any of the following factors may cause errors to be greater:                 <

#   1.  Errors in the source geospational data;                                <
#   2.  Cases involving irregularly shaped boundaries, such as those formed    <
#       by rivers and roads, etc.;  or                                         <
#   3.  Errors in the methods or programs that are used to compute the         <
#       approximations.                                                        <
