EFB-Pro provides a standard library of current FARs, advisory circulars, AIM and TFRs.  There are also links to Icing level (via ADDs) and the National Airspace Status board (delays throughout the US).  An internet connection is required for these services.

You may also setup 7 personal documents, such as MELs and Operation manuals, either online or on the iDevice.  Simply click on the Setup user link and enter a title and a path to the data.  The document format can be any format supported by the device.
