UAL does not use use the 'standard' Airbus Checklists, indeed their Avionics Smoke procedure is very straight forward by comparison and covers all the important aspects of the situation.
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.
The UAL checklist later mentions: IF SMOKE AFTER 5 MN:
EMER ELEC GEN 1 LINE ......OFF, which leads into the EMER ELEC CONFIG. etc.
Again, could this be interpreted as a positive if the Avionics Smoke ECAM Warning still exists?
My point is that Smoke and Fire are unquestionably one of our greatest threats and their should be little or no doubt how to proceed if faced with this problem, whether it is a training issue or checklist design, we need to be very certain what to do and when to do it. There can be no ambiguity.
