Sudden Twang-in contrast to your idea, if the plane is within about ten miles or so of the runway when the fire bell & lights come on, would it be better to pull the affected engine to idle power (once the rudder into the good engine is "cranked in" and the heading control, power and speed are stable with desired single-engine flaps and gear all down, start the APU...)? When an emergency has been declared and you are on the ground, smoothly reverse only the good engine? This has already been suggested: focus only on flying the plane using one engine, unless a few minutes or more from the airport?
How about fire lights/bells on takeoff (normal flap setting on long runway) a bit over 100 knots-cancel the bell and continue? If so, how many Captains brief this during the first leg of a trip?
