1 hour a week of extra rest?
'8 in 24' is a 'look-back' issue for rest, but then 'Nevets' mentions "an increase in block hours", so I assumed that he was talking about the maximum 8 hours of flying that could be done in a duty period - though the 8 hours of flying is a duty period limitation, not a 24 hour limitation (though most pilots only work 1 duty period per 24 hour period).
Assuming he WAS talking about rest, it'd be 9-10 hours of rest in a 24 hour period, which would increase minimum rest 1-2 hours per 24 hour period, not per week (it'd be 2-12 hours increase in rest per week, depending on how long your trip is and a variety of other factors).
This is the real issue with the FAR's, to me. Not only are they outdated, but they are unnecessarily difficult to remain in compliance with, IMO. Reduced Rest, Compensatory Rest, look-back, 1 in 7, 8 in 24, etc; when one pilot writes "8 hours in 24 increased to 9-10 hours" and it's not even clear whether they are talking about flight time in a duty period or min rest in a 24 hour period to another pilot, that should be a sign that things are too complicated.
I hope that the new regulations not only reflect a modern understanding of the science of fatigue, but also are easier to interpret and implement for both pilots and airline staffing departments.
