90 secs is the time required for a (trained) pax load to evacuate an aircraft, through half the available exits, for said aircraft to achieve certification. It has no bearing on the 'real life scenario' time which would depend on many variables.
I didn't know there was an SOP which required FD to use the windows/ropes.
Surely, depending on the conditions aboard, this could have been the time for a Precautionary Rapid Disembarkation - which Flybe haven't got as an option.
Thoughts?
