Rainboe...good point about the union. Unfortunately our union is at the embryonic stage hence does not yet have a mehanism in place to deal with this type of thing. I was rather hoping that ICAO may have had something definintive. I have seen some parts of ICAO Annex 13 which refers to CVR but it does so only in general terms. As said before , we are 20 years behind you guys. Was rather hoping that one of you may have some sort of written guidance either from your local regulatory authority OR your own union to which I could refer and / or peruse.
