ICAO Doc 10153:2025

This manual provides updated guidance material on those parts of the Operations Manual (OM) which are usually developed by the operator. An essential element leading to the approval of an OM is the development and specification of an appropriate approach to the supervision of operations; this manual has been prepared to provide guidance for regulators on developing such supervisory capability. In addition, the OM serves a primary role in regulatory oversight and the issuance of an air operator certificate.
