Which is not part of the briefing criteria established by the SOP?

The briefing criteria established by the Standard Operating Procedures (SOP) for flight operations typically cover several key elements that are crucial for ensuring safety and effective communication among crew members. Among these elements, "I'M SAFE" is a mnemonic addressing personal health and fitness, weather criteria are necessary for safe navigation and operations, and ORM (Operational Risk Management) is essential for assessing and mitigating risks associated with the flight.

Airfield frequencies, while important for communication during operations, are often not listed as part of the formal briefing criteria outlined in SOPs. Instead, they are generally considered procedural information that pilots are expected to familiarize themselves with prior to flight, rather than a mandatory briefing element. This distinction underscores that while communication frequencies are important, they do not fit into the standardized briefing criteria that ensure all critical areas of flight safety are covered. Therefore, airfield frequencies can be viewed as information related to operational procedures rather than a briefing element that needs to be consistently addressed in every flight briefing context.
