Authorisation course of

Following its TCO evaluation, EASA validates the international Air Operator Certificates (AOC) by issuing an EASA TCO Authorisation accompanied by Technical Specs, setting out the scope of operations authorised within the EU.

The TCO Authorisation course of consists of three distinct phases: Software, Analysis, Authorisation. All TCO Authorisation holders are topic to EASA steady monitoring of their security efficiency, which incorporates periodic file opinions.
