Requirements for pax armrests to be down on takeoff/landing
We all know the announcement that pax armrests must be down for takeoff/landing, but there are also a few unfortunate pax who get seated beside someone so huge they are told to put the armrest up as otherwise Mr Tubby can't get into his seat.
Is there any formal requirement on this ? And if "armrests down" is a safety procedure how is it allowed to go out of the window on certain occasions ? Or is it just a case of those unfortunates in this situation having to obey the lawful instructions of the crew, whether they say "up" to one and "down" to another ?
