Capt Claret, Im very aware of the rules and regs in Australia, as I started my flying career there. Everything is in black at white, trans at 10,000 at all times. Set 1013 passing Trans alt set QNH passing trans level. But in the UK It cant be that simple. Controlled 6000, uncontrolled 3000 or what ever it says on the plate. But there is no simple diagram like there is in the Aus jeps. In my operations manual it say when you cleared to a flight level set 1013 and when your cleared to alt set a QNH.
