Air Operator’s Certificate (AOC)

In this article, we will examine what is Air Operator’s Certificate (AOC)?, what is it for?, how to get it?, and what are the other details?

AOC is a document that allows an air operator company to use aircraft for commercial purposes in certain subjects and areas. If the operators want to use their aircraft for commercial purposes, they must purchase AOC.

According to the definition of ICAO; AOC is a certificate authorizing an operator to carry out specified commercial air transport operations (ICAO Annex 6).

Besides, AOC certificate refers to Air Carrier Operating Certificate in USA.

The AOC certificate is an approval given to the operating company by the relevant national aviation authority (NAA). The AOC document generally checks whether the necessary systems are in place to protect the operator’s assets, personnel and public safety. In addition, the AOC document determines which type of aviation activity the operator is permitted to and which type of aircraft it can use.
