Quote the FOM
FOM Chapter 21 page 5:
FTL 1.1
Intent of this Scheme:
In essence the CAR requires that a crew member shall not fly, and an operator shall not require him to fly, if either has a reason to believe that he is suffering or is likely to suffer, while flying from such as fatigue as may endanger the safety of the aircraft or of its occupants.
I think that the above (for us crew members) applies to us pretty much all of the time!
The words "require" "shall not" "suffering" "likely to suffer" "endager the safety" as above means that we should be not fit to fly on the majority of sectors which we do. However we do.
Maybe it's time to follow the rules as they are laid down and then wait to see what happens.
