EW73...
You are right, I have never flown 3 crew, hence the "caution" in my statement. But are you really saying, maybe on a twin, with a Fire Warning at V1, the FE will be pulling the (a?) TL back (unmonitored?), while the aircraft is still taking off / rotating?
Or would there be a CRM / team discussion about the indications, after establishing a safe flightpath, a diagnosis, decision, and then decide who will do what (drills, QRHs, memory etc.).
I would still challenge an FE, on a 14 hour flight, to pick up with a 50%+ chance, in any 10s period, those indications, diagnose and action something in time to prevent the disintegration
