BOAC- quite.
Flanker- you are missing a whole lot of points.
If, within the scope of CAP371, you have a minimum of 9 hours in the hotel, there is no reason at all that you shouldn't get 8 hours sleep.
Any half competent hotel should be able to rustle up a room-service meal in 20 mins or so, and it never takes me more than ten minutes to prepare for the morning. The point is that as a professional, any pilot should make sure that they maximise their rest time when on a short rest period- the pilot has as much of an obligation to ensure flight safety as the airline does. One of the telling points about the recent Channel Four documentary was not so much the amount of alcohol they (allegedly) consumed, but that they knowingly (in one case) stayed up until 3 am or so when they knew they had an early report- not much interest in flight safety there then! This is, unfortunately, far too common.
If you find it difficult to sleep in a hotel, it isn't going to matter if you are there for an extra hour- you will still be knackered. That is the nature of the airline business, where night-stops are involved.
The other point you miss is that if airlines routinely roster you for min rest followed by max duties, you will very quickly use all your available duty hours- with the inevitable result being lots of time off! Most airlines are not that stupid, they know it is an inefficient way of rostering.
The reason for distinguishing between fatigue and tiredness is that they have different legal meanings (as well as different definitions) which is important when arguing the issue.
Like I said- this is more about T's & C's than flight safety (which is fair enough).
