"Leaving" or "Left" Altitudes (ATC'ers pls)
Vacating maintained FL's/ALT's, AIP says to report - LEFT FLxxx etc.
A large Aussie Airline tells their pilots that the word 'LEFT' is only to be used with heading instruction/confirmations IE "LEFT HDG xxx" BUT
Does "LEAVING" FL's/ALT's satisfy ATC'ers requirements for leaving/left maintained altitudes? or not???
