Now it's looking really good!
Yes!
No?
How do airlines brief the pax in the emergency rows, apart from telling them "You MIGHT be asked to assist.......in the unlikely event of a blah blah".
If it REALLY is so important to have specific people assigned to emergency row exits, then the Civil Aviation authority needs to predicate some specific pre-flight briefing of a RESPONSIBLE nature, to the airlines.
Likewise, the airlines need to realise that because BY LAW, they are required to vet who occuppies designated emergency exit rows, that "in the unlkely event of an emergency", those "designated occupants" have been made LEGALLY responsible for the SAFE evacuation of the fare-paying pax.
