However, similar to the Airbus checklist there is a line, 'IF PERCEPTABLE SMOKE', which I suspect might be interpreted by some as a positive, if they have an Avionics Smoke ECAM warning. I am not suggesting this happened in this case, as I too look forward to the report when it comes out.
That is the rational way of understanding it.
I'm not trying to prejudge the matter, either. In fact, I'm not commenting on their performance at all. But anyone on these forums who suggests their decision to return was wrong
solely because they failed to see or smell smoke is bonkers. That nothing more than outcome bias, which is pure error.
