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.

The report and India’s inspection order referred to an advisory from the Federal Aviation Administration in 2018 that recommended that carriers using Boeing models, including the 787, inspect the locking mechanism of the fuel control switches to ensure they could not be moved accidentally.

The sudden movement of engine fuel switches has taken centre stage in the investigation of the Air India Boeing Dreamliner crash that killed 260 people in June, the world's worst aviation disaster in a decade.
