The FAA offers instrument approach procedures on their website free of charge (FAA Charts). Is there a similar site provided by EASA or the EU?
Eurocontrol has an online repository of European Aeronatical Information Services.
You'll need to register, but the basic service is free.
By default, the application is JAVA applet based, which works not in the best way. After logging on, you can change the default behaviour to HTML based, which makes it more user friendly.
Then clicking "Enter Application" will bring to the next level.
Here you'll find several reporting options, but what you are interested in is located under "PAMS Light [AIP]"
Select the country you are interested in, "Charts" for AIP type and "AD" for Aerodrome and there you have the charts.
Each European country has it's own set of charts (AIP) and they're all different. Jeppesen company is making big buck by collecting data from national AIP's and then converting it into single unified output format. Lido company is also making the same thing, but they have less airports in their database and it's only for C, D class aircraft (i.e. for airlines).
