but with all the other sounds and warning probably would be much complicated to comply with this simple rule
Nope its your job to be able to see through the smoke and tackle the fire. Its the reason why you call yourself a professional pilot.
In the main we are paid to be there for the very rare occasions that training and knowledge will save the day.
Without knowledge the BA 777 Captain at Heathrow wouldn't have reduced the flap to get rid of drag flap to give him a longer glide range. If he hadn't the plane would have crashed in a residential area and taken most if not all of the pax along with ground casualties. He managed to pull that knowledge out of his head with a twin engine failure Which I suspect will have a similar numbers of alarms and lights flashing as AF477.
That simple rule saved hundreds of lives, and more importantly it saved his own.
