High Altitude Enroute Charts
High Altitude Enroute Charts are used for aircraft navigation above 18,000 feet in the United States. The charts show the locations of radionavigations aids (VORs, etc.), airports, intersections, airways, etc. Unlike Sectional Charts, these charts do not show ground topographic and visual navigation features.
These charts have been merged together to create seamless coverage for the entire lower 48 United States and Alaska. Unfortunately, it does not look like I will be able to add the Caribbean, as those maps use an unknown projection system (if anyone happens to know how to georeference the Caribbean maps, let me know and I’ll add them).
These charts were purchased from the National Aeronautical Charting Office (NACO) and are NOT CURRENT. They are for simulation and entertainment purposes only!!

Many times, you can get outdated air nav charts for free at your local airport. I have a huge pile of sectionals that I got from the map library at a local University. There’s no sense in buying the real, up-to-date charts if you’re not actually using them to fly!
Eric, you’re correct. The trick is getting them scanned. Easier to buy the digital maps from NACO than to track down a scanner big enough to scan them. The High Altitude Charts only set me back about $15.
The Low Altitude Charts are a bit more expensive. If someone already has the digital Low Alt Charts and is willing to send them my way, that would work also.

In your aviation mapping did you ever get the DoD enroute chart set from NIMA back when the DAFIF was publicly available? I guess now it is a bit dated (30 Aug 2007 last issue).
I did get some of those charts way back when. But I don’t have them anymore and I wasn’t able to georeference them because they didn’t provide the projection information. But if anyone still has them, I could take another look at them.
I wanna low-alt IFR enroute.
If I could get 10 or 11 people to donate $5 each, I’d buy them and put them online. Or maybe someone already has them and can get them to me. Otherwise, it’s hard for me to justify the cost on my own.
What is the map projection for these High Alt E/R Charts? I’m guessing Lamberts Conformal Conic with 33° & 45° N standard parallels. If so what is the central meridian?

But they all had to be converted to Geographic Projection for Google Earth :)
