Which of the following statements with regard to Black Boxes used in modern aircrafts is/are correct ?
- They carry a beacon emitting red light pulses to facilitate underwater detection.
- They record both the cockpit voice and flight data.
- Their memory units are made using either stainless steel or titanium.
Select the answer using the code given below :
Detailed Explanation:
Statement 1 is incorrect because black boxes use an Underwater Locator Beacon (ULB) that emits acoustic/ultrasonic signals, not red light pulses, for underwater detection.
Statements 2 and 3 are correct. Black boxes record both cockpit voice and flight data, and their crash-survivable memory units are protected by stainless steel or titanium.
Therefore, Option B (2 and 3 only) is correct.
A "black box" is the collective term for the Cockpit Voice Recorder (CVR) and Flight Data Recorder (FDR). These devices help investigators determine the cause of an aircraft accident. They are designed to survive extreme impact, fire, and deep-sea pressure.
