Key Takeaways:
The Black Box of AI 171:
- A black box, technically known as an Electronic Flight Data Recorder, is an orange-coloured heavily protected recording device placed in a flight.
- It is used to investigate the details of the events immediately preceding an accident.
- Black Boxes are compulsory on any commercial flight or corporate jet where they are usually kept in the tail of an aircraft, where they are more likely to survive a crash.
- It usually takes at least 10-15 days to analyse the data recovered from the black boxes.
- Black boxes are also used in vehicles other than planes like railways, cars etc.
- Invention: Australian Scientist David Warren was the first to build a FDR/CVR prototype in 1958.
- Parts: The “black box” is made up of two separate pieces of equipment: the Flight Data Recorder (FDR) and a Cockpit Voice Recorder (CVR).
- FDR records things like airspeed, altitude, vertical acceleration and fuel flow. CVR records the conversations in the cockpit.
