A Black Box, despite its name, is an orange-coloured electronic device used in aircraft to record crucial flight information and cockpit communication. It plays a pivotal role in understanding the causes of air accidents. The tragic crash of Air India Flight AI171 in Ahmedabad (June 2025) once again brought the significance of the black box into focus.
What is a Black Box?
There are two major components of the black box:
1. Flight Data Recorder (FDR):
- Records technical parameters like altitude, speed, engine performance, flap positions, fuel levels, etc.
- Can store hundreds of flight parameters over several hours.
2. Cockpit Voice Recorder (CVR):
- Captures audio inside the cockpit: ), etc.
- Stores around 2 hours of cockpit audio.
These devices are designed to survive extreme conditions:
- Temperatures up to 1,100°C
- Deep-sea pressure up to 6,000 m
- High-impact forces due to crash
Significance in the Recent Ahmedabad Crash (2025):
Overview of the Crash:
- Air India Boeing 787, en route to London, crashed just 17 seconds after take-off.
- Crashed into a medical college hostel; over 270 people lost their lives.
- Only one survivor from the aircraft.
- The aircraft failed to gain altitude, and eyewitnesses reported an abnormal flight path.
Black Box Recovery:
The Flight Data Recorder (FDR) was recovered from the rooftop of a building near the crash site.
The Cockpit Voice Recorder (CVR) is yet to be found (as of June 14, 2025).
Expected Insights:
The FDR will reveal whether the aircraft's flaps, landing gear, or engines malfunctioned or were mismanaged.
One theory suggests flaps were retracted too early, resulting in loss of lift.
The CVR would help confirm whether it was a technical failure or human error (like miscommunication between pilot and co-pilot).
Why Black Boxes Are Critical in Investigations:
1. Establishing Sequence of Events:
Determines exact altitude, airspeed, and aircraft configuration at every second.
2. Identifying Root Cause:
Confirms whether failure was due to technical malfunction, pilot error, or external factors (e.g., bird strike, weather).
3. Preventive Measures:
Insights are used globally to modify standard operating procedures, training modules, and aircraft designs.
4. Legal and Compensation Matters:
Helps assign responsibility and guide legal outcomes for victims' families.
Challenges in Black Box Use:
- Often hard to retrieve due to:
- Deep sea crashes
- Fires and structural collapse
- Delay in CVR recovery can delay investigation
- Data corruption (though rare) can affect reliability
The Ahmedabad air crash highlights how the Black Box remains the most critical tool in aviation safety analysis. Its data can prevent future tragedies by offering transparent and technically precise insights. In an age of increasing air travel, such tools are indispensable for ensuring accountability, learning from errors, and improving aviation protocols globally.
