When doing a manual PIN or using ePIN, is it acceptable to only inform the PIC of the total number of souls on board?

In aviation operations, particularly in emergency situations, it is crucial to maintain clear and thorough communication regarding the total number of souls on board (SOB). Informing only the pilot in command (PIC) of the total number of passengers and crew members is insufficient and does not adhere to standard safety protocols.

The total number of souls on board is a critical piece of information for several reasons. It is essential for the safe management of the flight, especially in emergencies where evacuation procedures may need to be executed. Additionally, accurate passenger counts are important for search and rescue operations if an aircraft were to become lost or require assistance.

In many regulatory frameworks and best practices, it is mandated that all relevant parties, not just the PIC, should be informed of the total number of souls on board. This transparency helps ensure the safety and accountability of everyone involved in the flight, as it allows for better planning and resource allocation during potential crises. Therefore, not fully informing regarding the total number of souls on board is not acceptable.
