Kulverstukas;
Thank you for this information.
These "tests" miss the point.
Under no operational and technical circumstances should above-idle engine thrust be available / selectable to cockpit crew when the reverse selection has been made and the reversers are not in the fully deployed position.
What have I missed in the intent of these tests? For me, this smells of finding ways to blame the crew for the overrun. I don't know the actual operation of how reverse is selected in this aircraft, but is there any news regarding fixing the system that permitted above-idle thrust with reversers stowed while reverse was being called for by the pilot?
