Original Summary

archive.aero is a free viewer for historical FAA sectional charts. Drag the timeline to see the charts in effect on that date. It&#x27;s about 7,600 chart sheets stitched into one mosaic per edition. The scans come from the National Archives, the FAA, and charts contributed by the public. It&#x27;s built on GDAL and PMTiles, so there is no tile server or backend. The browser reads tiles straight from Cloudflare R2 with range requests.<p>I&#x27;m a student pilot in North Texas and I always wanted a &quot;ForeFlight time machine&quot; to see what changed between editions. The gaps are at <a href="https:&#x2F;&#x2F;archive.aero&#x2F;contribute" rel="nofollow">https:&#x2F;&#x2F;archive.aero&#x2F;contribute</a> (mostly 1970 to 2005) if you have old charts and would like to send them to be scanned.
