Final answer:
Aircraft manufactured after October 11th, 1991, for 10 or more passengers are required to have a Flight Data Recorder (FDR) and a Cockpit Voice Recorder (CVR) to enhance safety and facilitate accident investigation.
Step-by-step explanation:
Aircraft manufactured after October 11th, 1991, configured for 10 or more passengers, and requiring a minimum of two crew members according to the type certificate must be equipped with a Flight Data Recorder (FDR) and a Cockpit Voice Recorder (CVR). Both pieces of equipment are crucial for investigating incidents and enhancing future safety. The FDR records multiple parameters of flight performance, which can be analyzed to understand the aircraft's behavior prior to an incident. The CVR captures all audio in the cockpit, including pilot conversations, alarms, and background noise that can provide context in the aftermath of an event. Safety measures and regulations in the aviation industry are continually refined to prevent accidents, and these devices are part of an essential safety protocol that includes rigorous checklists.
