when Boeing changed it to read and do, most companies followed suit
oh dear,if people only knew the truth..Being modify when airlines have incidents/accidents and the modification is mandated..helios etc..do you think we really need a checklist entitled #Warning Horn#?Same with Boeing SOP change and the evac as well,which in my mind is definitely a MEMORY checklist.Someone screwed up a real evac though,so they changed it to a read and do..now all we need is an accident where checklist delays an evac following a catastrophic fire and theyll change it back.
Its the same principle as FO lands on wet rwy and skids off..reaction is ban all FO landings(last thing you should do of course)..same principle here..evac is obviously not suited to read and do(unless its a non-event)..with a catastrophic fire/smoke situation,I would never read and do despite what some smart alec pedant instructor says.You should know it in your sleep like the engine fire or smoke(another non-memory!!)
