What does 'Souls on Board' refer to?

'Souls on Board' is a term used in the aviation industry to refer to the total count of all individuals aboard an aircraft, which includes both passengers and crew members. This count is crucial for various operational reasons, including safety protocols, emergency situations, and weight calculations for takeoff and landing.

By considering every person on board, including those who are not paying customers but are essential crew members assisting with the operation of the flight, this term helps ensure accurate communication and operational transparency. Understanding this distinction is vital for flight safety and efficient management during aviation operations. The other options do not encompass all individuals aboard, focusing instead on baggage, weight, or specific passengers, which would not provide a complete overview of those present on the flight.
