What does the FOM primarily standardize in flight operations?

The Flight Operations Manual (FOM) is primarily focused on standardizing practices and procedures during flight operations. This includes guidelines for pilots and crew members on how to conduct operations safely and efficiently in a variety of situations. The FOM covers important areas such as pre-flight checks, communication protocols, emergency procedures, and operational limits. By establishing standard procedures, the FOM ensures consistency and safety across all flight operations, which is crucial for a smooth and regulated aviation environment.

The other options, while relevant to the overall airline experience and operations, do not fall under the primary purpose of the FOM. In-flight meal services, technical specifications for aircraft, and check-in procedures for passengers are managed through different manuals and guidelines specific to those areas. These elements are important but they do not encapsulate the core focus of the FOM, which is centered around flight operations.
