DA,
It indeed got a bit late last night and therefore thanks for your explanation of what (in a nutshell I assume) is the QF fuel policy - makes sense now why you were talking about alternate minima AFTER dispatch if destination = alternate (ie. you don't have one).
As I indicated in my previous posts in my company we ALWAYS carry an alternate but one remote destination (Perth of all places) and the conditions and TAF to be met for latter are very strict.
I guess your fuel policy works alright if the forecasts are good enough - the only thing I am not comfortable with is its application at a single runway destination; but that discussion deserves a different thread.
