IO540,
I am conscious of being a little out of my depth (having never flown fixed wing) but what would the effect of opening a door have on your stall speed, particularly if it is asymetric?
I have had a couple of smoke in cockpit events, both of which were (fortunately) on the ground and both of which were taken care of by switching the offending item off. If it was a laptop, I don't suppose the power off will have much effect, and on a windows machine would take forever. "Are your sure you want to shut down" "Of course I am $£$£$$% sure"
