FDR’s and CVR’s were originally developed to speak when the pilots were no longer alive to speak.
I believe they are used for more than that these days... I think that’s what we refer to as “mission creep”.
A little bit like internet metadata monitoring, which in my country was introduced to capture terrorists and paedophiles. Most recently it was reported that a local government was using it to capture and fine owners of unregistered pets.
Out of interest, does anyone have any links to current regulations around the world where the CVR may be accessed when the pilots are still available to tell the story?
When the offices of our CEO’s and politicians have CVR’s, maybe I’ll agree to this.
