So what are the official reasons in Air Canada's ops manual for saving a CVR recording. If not available, what about at your airline?

I've been made aware that since 2010, Canadian pilots and ground personnel must review rules and procedures re: FDR/CVR deactivation on equipped aircraft -- at least annually -- as part of their recurrent training. And the Commercial Air Service Standard (CASS) requires inclusion of the deactivation procedures in the Operations Manual.

Air operators are requested to review their training programs to ensure all flight crew members and ground personnel receive adequate training with regard to the proper procedures to safeguard on-board recorded data following an occurrence. In order to meet the above stated requirements of the CARs and the CASS, the following training should be provided to the flight crew members and ground personnel during initial and recurrent training sessions:

1. Initial and annual recurrent training that addresses the importance of preserving information held on a CVR and/or FDR;
   
2. Initial and annual recurrent training that addresses the proper procedures for disabling a CVR/FDR following an incident or accident;
   
3. Awareness of the consequences of incorrectly disabling a CVR and/or FDR following an incident or accident; and
   
4. The Air Operators training program should contain a provision that ensures all flight crew members and ground personnel are trained regarding any specific aircraft differences or procedures concerning the disabling of a CVR and/or FDR.
