What is FCOM in Aviation? (Flight Crew Operating Manual)

In the world of aviation, safety and precision are of paramount importance. To ensure smooth and efficient operations, flight crews rely on various manuals and documents. One such crucial resource is the Flight Crew Operating Manual (FCOM). The FCOM serves as an indispensable guide for pilots and flight crew members, providing them with comprehensive information about the aircraft they operate and the procedures they must follow.

The Flight Crew Operating Manual (FCOM) is an official document developed by aircraft manufacturers and approved by aviation regulatory authorities. It contains detailed information about the specific aircraft type, including its systems, limitations, and operational procedures. Considered the “bible” for flight crews, the FCOM serves as a reference for all phases of flight, from pre-flight preparations to post-flight procedures.

The Importance of the Flight Crew Operating Manual (FCOM)

The Flight Crew Operating Manual (FCOM) plays a vital role in ensuring aviation safety. Let’s explore the key reasons why this document is of utmost importance:

1. Safety and Standardization

The primary objective of the Flight Crew Operating Manual (FCOM) is to maintain safety standards in aviation. The FCOM provides flight crews with accurate and consistent information about the aircraft’s systems and procedures, enabling them to operate the aircraft safely and effectively. By standardizing the operating procedures, the FCOM ensures that all flight crews follow the same best practices, minimizing the risk of accidents.

The FCOM includes detailed checklists and emergency procedures, allowing flight crews to respond swiftly and correctly in critical situations. It covers a wide range of scenarios, from engine failures to cabin depressurization, providing clear step-by-step instructions for the crew to follow. This comprehensive approach ensures that flight crews are well-prepared to handle any emergency that may arise during a flight.

Furthermore, the FCOM contains operationally significant information such as limitations, performance data, and weight and balance considerations. By adhering to these guidelines, flight crews can optimize aircraft performance and maintain a safe operating environment.

2. Standard Operating Procedures (SOPs)

The Flight Crew Operating Manual (FCOM) serves as the foundation for defining Standard Operating Procedures (SOPs) for a specific aircraft type. SOPs are a set of predetermined actions and guidelines that flight crews must follow to ensure a consistent and efficient operation.

By incorporating the SOPs outlined in the FCOM, flight crews can streamline their workflow and achieve optimal performance. SOPs cover various aspects of flight operations, including pre-flight inspections, cockpit checks, taxi procedures, takeoff and landing procedures, and emergency protocols. These standardized procedures improve crew coordination and enhance the overall efficiency and safety of the flight.

Additionally, SOPs help flight crews anticipate and mitigate potential risks. The FCOM provides guidance on conducting risk assessments, identifying potential hazards, and taking appropriate preventive measures. By following a standardized process, flight crews can proactively manage risks and make informed decisions based on established procedures.

3. Training and Familiarization

The Flight Crew Operating Manual (FCOM) serves as a critical training resource for pilots and flight crews. During the initial training phase, pilots extensively study the FCOM to familiarize themselves with the aircraft’s systems, limitations, and operational procedures.

The FCOM provides in-depth explanations and visual representations of the aircraft’s various components, their functions, and the associated procedures. Flight crews learn about the aircraft’s avionics systems, flight controls, electrical systems, fuel systems, and more. This knowledge is essential for pilots to understand how their actions affect the aircraft’s performance and to make informed decisions during flight operations.

The FCOM also plays a crucial role in recurrent training and proficiency checks. Flight crews review the manual regularly to refresh their knowledge, keep up with any updates or revisions, and ensure consistency in their performance. This ongoing training helps maintain a high level of competency and readiness among flight crews.

Moreover, the FCOM enables pilots transitioning to a new aircraft type to quickly become acquainted with the specific procedures and operating characteristics of the aircraft. By studying the FCOM, pilots can efficiently adapt their existing knowledge and skills to safely operate the new aircraft.


The Flight Crew Operating Manual (FCOM) is an essential resource for flight crews in the aviation industry. It ensures safety, standardization, and efficiency by providing accurate and consistent information about the aircraft’s systems and operational procedures. By adhering to the guidelines outlined in the FCOM, flight crews can operate the aircraft safely, respond effectively to emergencies, and optimize performance. The FCOM serves as a foundation for developing Standard Operating Procedures (SOPs) and plays a critical role in training pilots and flight crews. Overall, the Flight Crew Operating Manual (FCOM) is a crucial tool that empowers flight crews to navigate the skies with confidence and precision.
