Who should flight attendants call for assistance during an emergency situation?

In an emergency situation on board an aircraft, flight attendants should prioritize calling emergency services for immediate assistance. This choice is correct because emergency services are specifically trained to handle urgent crises, such as medical emergencies, fires, or security threats. They have the necessary resources and expertise to manage a wide range of emergencies effectively.

While ground support crews and airport management play important roles in airport operations, they are not typically equipped to respond to in-flight emergencies in the same way that emergency services are. Ground support might be more focused on logistical support, and airport management can aid during broader airport crisis coordination, but they do not have the same direct capability to respond to emergencies like medical emergencies or fire on the aircraft itself. Therefore, in a time-sensitive situation, contacting emergency services is crucial for ensuring the safety and well-being of passengers and crew.
