A question to those of you in the business.
Voice recordings from the flight deck are on a continuous 30 minute cycle, hence in case of an accident the last 30 mins of the flight deck comms can (hopefully) be retrieved.
How long are the ATC radio recordings of comms with aircraft kept for?

ATC recordings kept for minimum of 30days - a lot longer if an incident requires the impounding of a tape.

Warlock,
In the US voice recordings are kept only for 14 days then the tape is re-used.

Mike,
I thought ICAO insisted on the 30 days retention??
The system I am using now uses DVD's but we all still talk about tape-changes!!!

Nope, in the US it has always been no longer than 14 days.

Most modern CVR's keep two hours of cockpit audio now but it can still be erased by the crew once the engines are shutdown. FDR keeps about 25 hours of data and cannot be erased by the crew.

Our digital recording system (voice and radar picture) records direct to hard disk, then archives to DVD every hour.
Each DVD is used for 48 hours, then stored for minimum 32 days before being formated and reused.
Operators/controllers have no access to the equipment exept during any replay activity when the equipment is operated in playback mode by duty engineer.
Works just fine!
Much simpler, quicker, and user friendly that ICR32...
