Normal rest at home is twelve
I wonder if what you wrote is what you mean. Many years ago the sensible Scandanivian FTL's allowed a 1 hour travel time home and back again. Thus 12 hours rest at home equalled 14hr off duty: which is what PSB hinted at. However, in only that regime wasrest at home considered. Every other FTL was time off duty - time on duty. Travelling was not considered. The time in some airports from stand engines off to car park can differ by 1 hour in both directions.
