Considering the obligation to store audio in the cabin to 25 hours
The Federal Aviation Administration (FAA) is considering extending the requirement for voice recording inside the cockpit to 25 hours. Currently, however, all new planes must memorize the audio of the last two hours, containing conversations between pilots, transmissions to the control tower, sounds and noises of various types. This is a change that the National Transportation Safety Board (NTSB) has been pushing for since 2018.
This change "will provide us with substantially more data to identify the causes of accidents", explained the administrator of the American skies regulator, Mike Whitaker, recalling that the US rule lags behind those in force in much of the world, such as Europe, which from 2021 requires the collection of 25 hours of audio recordings.
Furthermore, in 2016 the International Civil Aviation Organization (ICAO) adopted a new standard requiring the recording of the last 25 hours on all new aircraft starting from 2021. The issue has taken on new relevance after a series of near misses, often between a landing and a departing aircraft at the airport, raised an alarm on US aviation security.
