The Operations Manual Parts A–D is a standardized framework used primarily in commercial aviation—especially under EASA regulations—to organize and structure an operator’s core documentation. These parts collectively define how an aviation organization manages its operations, safety, and compliance.

Here’s a breakdown of each part:

• Part A – General/Basic
  Covers the overall policies, organizational structure, and general procedures. This includes company safety policies, responsibilities, and operational control.

• Part B – Aircraft Operating Matters
  Details procedures specific to the types of aircraft in the fleet. This includes normal, abnormal, and emergency procedures, performance data, and limitations.

• Part C – Route and Aerodrome Instructions
  Contains information about authorized routes, airports, and airspace usage. It includes operational requirements and restrictions tied to geographical areas.

• Part D – Training
  Outlines the training programs for flight crew, cabin crew, and other operational personnel. It covers initial, recurrent, and upgrade training requirements.

Maintaining and keeping these manuals up to date is vital for regulatory compliance and safety. Web Manuals simplifies this process by providing a powerful document management platform that supports real-time collaboration, version control, and compliance linking, ensuring that all parts of the Operations Manual are current and audit-ready.
