If they are stupid enough to make it one day as per the FTL's then who cares. That's a rule book which simply (actually - grossly complicated) which states their rostering limitations.
Only one person can determine if I have satisfactorily recovered from my previous flight(s) and that's me! I don't care a rats a^$e if they roster me to fly next day or not.
Their ridiculous rules will simply produce an increase in the SKF rate - and surprise surprise, they are!
Anecdotal story:
Visited the clinic the other day and was astounded to hear from one of the Doc's that pilots are asking them to determine if they are fatigued....
go figure!!!
What hope do we have with this degree of cowardice...
