Exie ; Ours just says "Engine fire" as evidenced by at least two "parameters. It does not talk about the parameters that produce a " warning". Engine failure is a failure and would be clearly evidenced by other control factors that, surely don't need at "least two other parameters". or deep discussion. Up to V1, a "failure" would be pretty obvious. I would not seek a second confirmation to a boot full of rudder.
Drifting a long way off thread though. Someone earlier asked about some thread about calling V1 before V1. There was one. That too drifted a long way off into the hand-bag swinging this is getting close to. We do call V1 at V1 minus 5 kts & even stress the speed, in knots, that the call will be made at.
Kathmandu AIB publication is the thread and I must, finally agree with all the others that, quite simply, rejecting after V1 proved horribly wrong.
