The best defenition i ever heard!
Really,its down to the dot.
AAI's new FOM chapter 7,edition nov06.is just about to crack...if CAA look's in to the content about def.of tvl and duty time...and reporting time...
It's amazing how they could get this printed,and of course any newhires or some young "son" in ops will ofcourse send U tvl to AMS and then operate to K.L ref. to FOM chp7...
Its so stupid written thats its very easy missunderstod,maybe that was the point from the start.
