Seatbelt signs - part of MEL?
Just been reading a thread on the unofficial forum for cabin crew at my airline, and it's been mentioned that we've got a 747 flying around with a huge number of "minor" technical problems.
One of these is the seatbelt/no smoking signs, which are apparently not working throughout the aircraft.
Is this legal? I thought that these signs were part of the MEL and the aircraft should not be operated without them...
