This online facility can be used to submit ARC data to the CAA. It does not allow the retrieval or correction of previously entered data.

As a consequence of EASA Regulation changes the ARC Online system has been updated to reflect changes to the ARC 15A and 15B formats. The new format requires that the total aircraft hours flown at the issue, or extension, of the ARC are shown on the ARC. Consequently, entering data in the hours flown field in ARC Online will be mandatory for all aircraft, with the exception of balloons and airships.
