Operations Manual (OM)

Operations Manual (OM)


An Operations Manual should contain procedures, instructions and guidance for use by operational personnel in the execution of their duties. (ICAO Annex 6: Operation of Aircraft)

The Operations Manual may contain some or all of the information contained in the Aircraft Flight Manual (AFM), but it also contains much other information regarding the way in which flights are to be conducted.

EU-OPS Requirements

The structure and content of the Operations Manual is detailed in EU-OPS 1.1045 and the referenced Appendix. In essence, the Operations Manual comprises four parts:

  • Part A. General/Basic. This part comprises all non type-related operational policies, instructions and procedures needed for a safe operation.
  • Part B. Aeroplane Operating Matters. This part comprises all type-related instructions and procedures needed for a safe operation. It takes account of any differences between types, variants or individual aeroplanes used by the operator.
  • Part C. Route and Aerodrome Instructions and Information. This part comprises all instructions and information needed for the area of operation.
  • Part D. Training. This part comprises all training instructions for personnel required for a safe operation.

Subsidiary Documentation

For ease of use, most operators create subsidiary documents, in particular a Quick Reference Handbook (QRH) or Emergency and Abnormal Checklist (EAC), copies of which are provided on every flight deck for the personal use of each member of the operating flight crew.

Amendment of the Operations Manual

Amendment of the Operations Manual - in hard copy and electronic format - is the responsibility of the Operator who has issued it. This is an important function of the flight operations department and must be carefully controlled to ensure that all officially issued and controlled copies of a Manual and any subsidiary documents (including copies of parts of the OM) are updated as part of the same action. It is normal for there to be a formal channel available which can be used to issue urgent individual changes to all holders of a Manual or a dependent document rapidly and for the full document text to be re-issued incorporating any individual changes issued since the previous edition at prescribed intervals of not greater than a calendar year.
