bfisk,
I'm not sure that he did, but that has also been addressed here. Under JAROPS, to reduce contingency from 5% to 3% one must have an ADEQUATE airport (thus we no attached weather requirements) lying within a circle whose diameter is 20% of the route distance (a minimum of 50miles) centred 75% alond the route.
Why adequate rather than suitable in this case? Dunno, but thems the rules.
