Final answer:
The CVR/DFDR, or black boxes, operate automatically during all phases of flight, including takeoff. They record aircraft, pilot, and environmental data essential for investigations after incidents.option a,
Step-by-step explanation:
The Cockpit Voice Recorder (CVR) and Digital Flight Data Recorder (DFDR), commonly referred to as the "black boxes," operate automatically to record critical information during flight operations. The correct answer to the question "When does the CVR/DFDR operate automatically?" is:
- A) During takeoff,
- B) When the aircraft is on the ground,
- C) In emergency situations,
- D) When the flight crew initiates it.
The primary function of these recording devices is to capture data such as aircraft performance, pilot actions, and environmental conditions. They turn on automatically whenever the aircraft is powered up and continue to record during all phases of the flight, including takeoff, climb, cruise, descent, and landing. In the event of an incident, the data preserved in these recorders is invaluable in helping investigators determine the cause.
