Operation Manuals are an essential set of documents that define all operational standards, procedures, responsibilities, and safety requirements of an airline. They are governed by ICAO regulations and the national civil aviation authority—such as the CAAT in Thailand.
These manuals ensure that pilots, cabin crew, dispatchers, operations control staff, and ground personnel perform their duties safely, consistently, and in full regulatory compliance.
Common Types of Operation Manuals
OM-A (General Basic Manual) Provides company policies, operational regulations, organizational structure, flight safety systems, and general operational guidelines.
OM-B (Aircraft Operating Manual) Contains aircraft-specific data: systems overview, performance, limitations, normal/abnormal procedures, and checklists.
OM-C (Route / Area Manual) Includes route information, airport briefings, terrain considerations, local procedures, weather patterns, and area-specific requirements.
OM-D (Training Manual) Defines training programs for pilots, cabin crew, and operations staff, including competency standards, assessment criteria, and CBTA/KSA framework.
