What is the primary purpose of a crash alarm?

The primary purpose of a crash alarm is to initiate emergency procedures. This alarm is designed to alert air traffic control and relevant personnel of a potential or actual emergency situation involving an aircraft. When the crash alarm is activated, it prompts a coordinated response to ensure the safety of the passengers, crew, and anyone on the ground. It typically leads to actions such as dispatching emergency services, alerting personnel around the airport, and implementing established protocols to manage the situation effectively. This function is critical in minimizing the impact of an incident and ensuring that aid is rendered as quickly as possible.
