How should pilots communicate their weather observations according to the FOM?

Pilots are required to communicate their weather observations by following the outlined reporting procedures as specified in the Flight Operations Manual (FOM). This systematic approach ensures that critical information is conveyed accurately and consistently to all relevant parties, such as Air Traffic Control and other pilots. Adhering to the prescribed procedures allows for a standardized method of reporting weather conditions, facilitating better situational awareness and safety in flight operations. By following these guidelines, pilots contribute to a shared understanding of the environment they operate in, which is essential for making informed decisions.

Communicating observations solely during severe conditions would mean that valuable weather information could be missed during less severe but still significant weather events. Checking with co-pilots prior to reporting may delay communication and potentially compromise the urgency required in certain situations. Informal communication channels do not provide the reliability or uniformity needed for effective reporting, potentially leading to misunderstandings or the omission of crucial weather information.
