Pontious,
Please allow me to ensure you that I am far from ignorant regarding what actually happens and that for some 28 years I have not listened to crew feedback regarding 'what really happens' and indeed when I, previously, scheduled crew patterns I would always ask myself 'would I like to do this crew pattern?'.
Now this thread was about a 15 hour rest period in line with CAA CAP371 flight & duty time regulations but your post has moved it along to talking about volunteered increase reporting times, unrealistic flight scheduling and/or headwinds, whether a crew member chooses to drive home or take public transport after work, discretion reports, travelling times to/from hotels which is covered seperately in CAP371, flight delays etc. etc. etc.
You have moved it along totally off the topic to which I previously posted in response to, don't you think the Ops guys in the office have a problem driving home, with the sun in their eyes, after a 12 hours+ nightshift, don't you think that people other than pilots understand these problems, so please don't presume me/us as ignorant simply for pointing out that fatigue needs to be reported as actual fatigue and not 'mouthing off' months in advance.
