Im very curious. Virgin Blue has been very active in seeking exemptions from 'standard regulations' which enable them to reduce staff (see, amongst other things pilot duty time exemptions)
In June this year they argued and acheived a reduction in Cabin Crew on Boeing 737's, on the grouds that they have 'self help' exit seats and can therefor acheive 90 second evacuation of the plane.
Can anybody tell me if this is realistic ?
Has anybody done a 'live' or 'mock' evacuation with passengers on a 737 in under 90 seconds ?
Would this be assuming everybody was completely able bodied ? How often does that happen?
