What is the purpose of a klaxon?

The purpose of a klaxon is to alert crews for immediate aircraft launch. This type of warning device is specifically designed to produce a loud, attention-grabbing sound that can quickly notify personnel of urgent situations, such as the need to prepare aircraft for takeoff. In environments like military bases or airports, where quick response times are critical, having a reliable auditory signal like a klaxon ensures that all necessary team members can react promptly and efficiently to facilitate the launch process.

While options related to securing locations, indicating security breaches, or notifying maintenance teams are important in their respective contexts, they do not encapsulate the primary and specific function of a klaxon, which is primarily focused on mobilizing flight crews for immediate operational readiness.
