Every countrys' TA and TL is different. Does anyone have a site where different country's TA and TL are available?

Does anyone have a site where different country's TA and TL are available?We in the RC beta team were never able to find a single site listing all the world's Transition Altitudes - we had to do it the hard way.The authoritative source for such information is each country's Aeronautical Information Publication (AIP) and more and more of these AIPs are becoming available on-line. Unfortunately, many countries do not have a single TA but one which varies from airport to airport so a more-usable source is probably the approach and/or departure charts for individual airports - there are now many sites on the Internet offering these charts.Transition Levels, however, are a different kettle of fish because, in the vast majority of cases, the TL is a calculated value based on the TA and the current pressure and so can't be published in advance. I say, "in the vast majority of cases" because, as with everything in this world, there are exceptions to this rule and a few countries - New Zealand springs to mind - have both a fixed TA and a fixed TL! (The fixed TL situation is not simulated in this version of RC and all TLs are calculated.)As far as Radar Contact goes, the TAs the program is using are shown on the "Controller Info" page after you've loaded your flight plan. Once you've clicked "Start RC" the calculated TLs RC will be using are shown briefly on the advdisp display or you can refer back to the "Controller Info" page where this data also now appears below the TAs. Probably the most complete list of TAs in one place is in the file that RC uses although I wouldn't vouch for its complete accuracy. You'll find it in the RC4data directory in the file m4.csv. Open this file with only Notepad or a similar text editor and NOT Excel or other spreadsheet! You'll find the TA as the last figure against each airport - non-US airports for which we couldn't find a TA have the US 18,000ft as a default.Pete

Basically in the US it's the same, only US has fixed TA/TL (18.000ft / FL180) where as in Europe TA/TL depends per country/airport.
