We spend time researching and typing this guidance to avoid our aircraft owners and pilots getting into trouble. Goodnight.
daikilo,
I quite agree. What my 5th paragraph was getting at though is what iwantmyhols has said above.
What is this x ammount? Is it = 0? if so fine. But I am unconvinced that anybody KNOWS this. Also I am unconvinced that anyoen knows the exact concentrations in the predicted contamination areas.
I don't blame anyone at all. I think the VAAC did exactly what they were supposed to do and Nats did what they had to do initially. I just feel that much like the belated sending of an aged Arc Royal to pick up some punters, more should have been done to get quality data, much sooner.
