# > Airspace for Sterling, Illinois < # > < # > Data courtesy of Lynn Alley < # > < # > File created on Wednesday, 03 September 2008 at 03:17 GMT < # > < # > US AIRSPACE INFORMATION FROM NASR DATA EFFECTIVE 06/05/2008 < # > UNOFFICAL DATA - NOT FOR NAVIGATION < # > < # > The information in this file is composed of computed approximations of the < # > arcs and lines that make up various airspace boundaries, which 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) files 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 errors in the estimated positions < # > of arc center points and radii will be much larger); however, any of the < # > following factors may cause errors to be many times greater: < # > < # > 1. Errors in the NASR point data; (NOTE: NASR shape files for airspace < # > classes B, C, and D are currently designated as beta test < # > information, which will not be officially supported until sometime < # > later in 2008) < # > 2. Cases involving irregularly shaped boundaries, such as those formed < # > by rivers and roads, etc.; < # > 3. Cases where arcs form the boundaries of MOAs, Alert areas, or < # > Restricted or Prohibited airspace (due to imprecise descriptions < # > of such boundaries in the NASR files); and < # > 4. Errors in the methods or programs that are used to compute the < # > approximations. < # > < # > Altitude information for the ceilings and floors of special use airspace < # > contained in these files is unreliable due to the imprecise, natural- < # > language encoding of this information in the source NASR data. The same is < # > true for time-of-use information. Always refer to official sources, such < # > as current sectional charts, for authoritative information. < # > < # > Note that the software used to produce the approximations contained herein < # > has not been certified for navigational use -- CONSEQUENTLY, THIS < # > INFORMATION SHOULD NOT BE RELIED UPON FOR NAVIGATION. Use of this < # > information for any other purpose is solely at the user's risk. This < # > information is provided free of charge.
