Guys......
According to the report, "While the airplane was decelerating to a stop, the fire warning bell sounded. When the airplane came to stop, the captain called for the engine fire checklist. The third item on the checklist was to move the fuel control switch on the affected side (in this case, the left side) to the cutoff position, which shuts down the respective engine."
Where I work, on this type, there are memory items for this situation which will quickly shut down the engine, cut off fuel and discharge fire bottles. Is it different at BA with only a checklist which can take significantly more seconds to perform?
