The FAA is increasing cockpit voice recording time to 25 hours on new passenger aircraft from 2027. The regulation aims to prevent data loss in accident investigations.
The U.S. Federal Aviation Administration (FAA) has finalised a significant regulation that directly concerns aviation safety. Accordingly, all new passenger aircraft manufactured from 2027 onwards will be required to be equipped with cockpit voice recorders (CVR) capable of storing at least 25 hours of data. Under current systems, this duration is limited to just two hours.
FAA: “Significantly More Data Will Be Provided for Investigations”
In its published statement, the FAA emphasised that the new regulation:
“will provide accident investigators, aircraft operators and civil aviation authorities with significantly more CVR data to help determine the likely causes of incidents and accidents and to help prevent similar events in the future.”
Cockpit voice recorders capture critical moments of a flight, including pilot conversations, cockpit warnings and engine sounds, and play a vital role particularly in post-accident analyses.
The United States Had Fallen Behind Global Standards
The National Transportation Safety Board (NTSB) has been calling for this change since 2018. For a long time, the United States lagged behind international standards regarding the requirement for 25-hour recordings on commercial aircraft.
Europe has mandated 25-hour cockpit voice recording on new aircraft since 2021.
The International Civil Aviation Organization (ICAO), with a decision taken in 2016, had adopted this standard for all aircraft manufactured after 2021.
Lost Data Accelerated the Decision
The NTSB announced that following a runway incursion risk incident in 2023, the cockpit voice recordings of both aircraft were overwritten and could not be recovered due to the limited two-hour recording capacity.
The roots of this incident trace back to a serious safety violation in San Francisco in 2017, when an Air Canada Airbus A320 was mistakenly lined up with a taxiway for landing. The aircraft subsequently initiated a go-around after passing approximately 100 feet above two different aircraft positioned on the taxiway.
A Major Change Since 1966
According to FAA data, when cockpit voice recorders were first introduced in 1966, they were capable of recording only 30 minutes of audio. The new regulation is regarded as one of the most comprehensive safety steps taken in CVR technology over the nearly 60 years since then.
