New Delhi: The deadly Air India crash last month has renewed a decades-old debate in the aviation industry over installing video cameras monitoring airline pilot actions to complement the cockpit voice and flight data recorders already used by accident investigators. One of the industry's most influential voices, International Air Transport Association head Willie Walsh, a former airline pilot, said on Wednesday in Singapore there was a strong argument for video cameras to be installed in airliner cockpits to monitor pilot actions to complement voice and flight data recorders already used by accident investigators.

Aviation experts have said a preliminary report from India's Aircraft Accident Investigation Bureau (AAIB) raised questions over whether one of the pilots of Air India flight 171 cut off fuel to the Boeing 787's engines seconds after takeoff, leading to an irrecoverable situation.

The crash in Ahmedabad, India, killed 241 of the 242 people aboard, as well as 19 people on the ground.

As of now, "based on what little we know now, it's quite possible that a video recording, in addition to the voice recording would significantly assist the investigators in conducting that investigation on the issue of mental health," Walsh said.

Advocates for cockpit video cameras say the footage could fill in gaps left by the audio and data recorders, while opponents say concerns about privacy and misuse outweigh what they argue are marginal benefits for investigations. Video footage was "invaluable" to Australian crash investigators determining what led to Robinson R66 helicopter breaking up in mid-air in 2023, killing the pilot, the only person aboard, according to the Australian Transport Safety Bureau's final report, which was released 18 days after the Air India crash.
