Investigators could not hear what the Air Canada captain and co-pilot said to each other during the aborted landing because their conversation was recorded over when the plane made other flights, starting with a San Francisco-to-Montreal trip the next morning. Recorders are required to capture only the last two hours of a plane’s flying time I wonder what the procedure is in a near Miss like this. It looks like not enough of the 'process' to capture evidence kicked in soon enough. Judging by the photo and distances this looks like it was an imminent disaster, which hadn't been clear to me previously.

On top of that, storage is cheap. They can probably afford to keep conversations longer than 24 hrs.

  Storage is cheap today, it wasn't 30 years ago when these rules were put in place (And probably some of the systems manufactured)

    Retrofits to safety equipment are common when new issues are discovered. That said, an enforcement action or a procedure change is probably necessary in this case.

      For sure, and it might get changed now, but it wouldn't surprise me if planes are still flying with age old cockpit voice recorders, simply because the requirements on that front haven't changed. (Bearing in mind this is just an educated guess, I have no idea about whether or not they have changed)

    Of course the FDR/CVR might be newer but the airframe is 25 years old: https://www.flightradar24.com/data/aircraft/c-fkck https://www.flightradar24.com/data/aircraft/c-fkck

      30 was just a number I pulled out of the air because I have flown aircraft that were about that old. Of course, like you say, equipment could have been retrofitted so it's hard to know.

        I didn't mean to post that to correct you! If anything it confirms your point, really.

        Oh, sorry. You never know, some people are such nitpicks when it comes to numbers :)
