Hetfield, nnc0 tells me that you were not being unreasonable (that was never in question!).
Would you not consider that the links between these components could themselves have been compromised by the event and hence the ECAM warning may never get triggered such that you would only ever get the one alert – do you consider this eventuality to be such a low probability?
I guess if we searched through a few crash reports where fire was a factor we would see that the feedback available to the crew would be seen to be incomplete or misguiding in some cases. I assume with the workload you did not either did not have time to consider such a scenario or you reject it for other reasons?
I think you never mentioned what your own personal estimate on the time to land at the divert was (although others suggested it could have taken just as long as your chosen course of action). The divert was not perfect, but it was viable nevertheless? I assume you considered it to take just as long as to press-on?
Not a witch hunt, just interested as to your reasoning given the constraints placed upon you.
Cheers.
