depends on the landings, block hours and duty hours.
Bet 411A doesn't fly 95 hours block, 170 hrs duty and 70 landings each month in an aircraft -if you want to call it like that- like the EMB145?
Perfectly legal, but slightly tiring one would say.
Worst thing - I think - is Block hours are often used for the benchmark, while all the hours one might hang around at an airport are not considered by management.
