Updating links to airport charts
I've simplified the links to the FAA page which lists M57 airport approach plates, and to the PDF files of the plates themselves. The problem was that the plates are being updated every 28 days (the length of so-called AIRAC cycle), and since FAA doesn't keep old plates after they expire, the links will go stale within 1–2 months from the publication. From now on (unless FAA changes the structure of its website again), in order for the links to stay current all one needs is to replace the outdated AIRAC cycle designation inside the links' URLs with the most up-to-date cycle designation: specifically, one needs to replace a 4-digit YYCC number, where YY is 2-digit year, and CC is 2-digit cycle designation within the year (going up from 01 to 13 or 14). cherkash (talk) 02:17, 2 June 2011 (UTC)
