As Magplug says - a challenging exercise and I am not sure how I would react to that scenario. It would appear that pax steps are sort of 'in place' front and rear but presumably the decision was taken not to use them due to the 'fire' or the brave ground staff had scarpered when they saw smoke etc before they were moved up close?
Back to the 'Jet Airways' thread. How many of you would remember to lower the flaps (electric hydraulics still on, or on standby switch?) and get the pax to move away from the front door? There would, in that scenario, be one usable slide and two overwings on the starboard side. Passengers would already probably have their hand-baggage out of the lockers and in their hands.
Perhaps maybepilot and others would like to tell us how they would have reacted in the time available - as 'professionals'?
