Explanation:
The FDR (Flight Data Recorder) event button is located on the center pedestal of an aircraft's cockpit. Its primary use is for the pilots to mark a specific point in the data recording where an event or irregular occurrence has taken place during the flight.
This assists investigators in locating important data quickly during any post-flight analysis. When pressed, the event button will flag the recorded data at that specific time, highlighting an incident that the flight crew deems significant.
