NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FAA: REQUIRE ALL AIRCRAFT CURRENTLY REQUIRED TO BE INSTALLED WITH A COCKPIT VOICE RECORDER TO BE RETROFITTED WITHIN 2 YEARS WITH A CVR INSTALLATION DESIGNED SUCH THAT AN UNINTERRUPTED RECORDING FROM THE BOOM OR MASK MICROPHONES & HEADPHONES FOR EACH FLIGHT CREWMEMBER'S POSITION & FROM AN AREA MICROPHONE CAN BE MADE ON DEDICATED CHANNELS OF THE CVR. A SIDETONE SHALL BE PRODUCED ONLY WHEN THE TRANSMITTER OR INTERPHONE IS SELECTED, &, IN ADDITION, ALL AUDIO SIGNALS RECEIVED BY HAND-HELD MICROPHONES SHALL BE RECORDED ON THE RESPECTIVE CREWMEMBER'S CHANNEL WHEN KEYED TO THE 'ON" POSITION.
In plain language (FlightFinder summary)
The NTSB asks the FAA to require that within two years, all aircraft that already need a cockpit voice recorder must upgrade to a system that records uninterrupted audio from boom or mask microphones, headphones, and an area microphone on separate, dedicated channels. The system must also ensure that sidetone is produced only when the transmitter or interphone is selected, and that audio from hand-held microphones is recorded on the respective crew member's channel when the microphone is keyed on.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
