Question

Pressing the flight data recorder (FDR) EVENT switch will:

a) Initiate recording
b) Stop recording
c) Trigger an event marker
d) Cause the DCUs to place a marker in the FDR memory for quick data retrieval

Answer 1

Pressing the flight data recorder (FDR) EVENT switch will trigger an event marker on the FDR, helping investigators analyze critical information quickly.

Step-by-step explanation:

Pressing the flight data recorder (FDR) EVENT switch will trigger an event marker on the FDR. This means that when an important event occurs during a flight, such as engine failure or a sudden change in altitude, the pilot or flight crew can press the EVENT switch to mark that specific moment in the recording. This marker helps investigators analyze the data log and find critical information quickly.
