Maybe someone can provide some examples of accidents or incidents in which the investigation stated that cabin crew fatigue was a reason for loss of life or injury to passengers.
twiggs,I'll try and treat your question seriously.For a situation as you are alluding to and there is loss of life the incident is usually a catastrophic one.
It is hard to test the fatigue levels of someone who is deceased or someone who has survived an accident and is recovering in hospital and is under medication.Even if the F/A testifies that they felt fatigued at the time of the accident it would be hard to quantify.
The pilots are a little different in that they are operating in a work environment with voice and data recorders.The performance of the aircraft can be analysed to interpret the actions of the pilots prior to an accident.
How can you do the same for f/a's?
There are no machines recording the actions of the f/a prior and during the accident.
So how can you ask for examples?
When you said
I think it unlikely
you are saying you don't believe there is any proof and that is exactly what the airline would be saying.
We all know that as human beings we are subject to tiredness the same as anyone else but to quantify it and get some legislation passed is going to be very hard.
