What should be included in a post-flight report according to the FOM?

The inclusion of any irregularities, incidents, and deviations from the Flight Operations Manual (FOM) in a post-flight report is crucial for several reasons. First, it ensures that the crew openly communicates any issues that may have arisen during the flight, which is essential for the safety and efficiency of flight operations. Reporting these factors allows for thorough investigations, identification of trends, and implementation of preventive measures to enhance safety protocols.

Additionally, documenting irregularities, incidents, and deviations helps maintain accountability and compliance with regulatory standards. This practice fosters a culture of transparency and continuous improvement, which is paramount in aviation safety. By capturing this information, it can be reviewed and analyzed by safety management teams to derive lessons learned and improve training and operational procedures.

While aspects like flight duration, passenger count, and weather conditions are important, they do not hold the same weight in addressing safety concerns as reporting any deviations or irregularities does. This focus on safety and compliance is the primary reason why option B is the correct answer.
