I guess you're referring to my earlier post:
. I suspect you are referring to excess fuel above minimum FPL fuel. That calculation does not take into account non-ideal parameters such as weather, traffic flow, ATC/NAV facilities, etc. etc.
That's not what I meant, maybe it's semantics.
I think just like many operators my operators minimum FPL fuel includes a contingency amount (usually statistically based) amount to cater for exactly the sort of non-ideals you describe. If you go with our FPL fuel you already have contingency built in for the most common non-ideals. Any excess fuel loaded above our FPL fuel (e.g for really carp weather) is therefore contingency plus .....
In any event and to clarify another point I've never had a phone call, e-mail or conversation querying any excess I've ordered.
