Not anymore . I had access to CRARs (Country Rules And Regulations) but not for now . I was reading something in the German CRAR where it was prompting pilots to ask for a descent clearance even in emergency because of German airspace being so congested . I read that shortly after changing procedures in my previous employer ; we were requesting clearance in emergency descent , the justification being basically what I saw in the German CRAR. But it wasn’t until I saw the list of changes in Airbus procedures that I realized it was probably Airbus itself which probably mandated this . The thing is , you will not find this in their manuals.
