I was told the reason CASA changed things to FRMS was so that Pilot's had the responsibility to call fatigued which wasn't an option under the old CAO.
A pilot must not operate an aircraft unless, at the commencement of the duty
period:
(a) the pilot has had the required minimum rest period free of duty; and
(b) the pilot has had the opportunity to take adequate sustenance; and
(c) the pilot is free of any fatigue, illness, injury, medication or drug which
could affect the safe exercise of his or her licence privileges.
2.15 An operator must not require or permit a pilot to operate an aircraft unless, at
the commencement of the duty period:
(a) the pilot has had the required minimum rest period free of duty; and
(b) the pilot has had the opportunity to take adequate sustenance; and
(c) the pilot is free of any fatigue, illness, injury, medication or drug which
could affect the safe exercise of his or her licence privileges.
It has always been pretty clear to me that I have a responsibility to call "fatgue" under CAO 48.
The problem nowadays is the "worlds best practise" "KPI stakeholder" management say "No, you are only tired, not fatigued."
Tell me where the line between the two lies...
