FDR - Flight Data Recorder. QAR - Quick Access Recorder. CVR - Cockpit Voice Recorder

after the accident or incident the commander must secure flight data records by:

turn off in MCDU safety plugs: CBMENU/CB BY SYS/FDR/CVR. And it must be noted in LDP-60

How long the IRS alignment on the ground can take?
