How to decipher recipes indicating AAUs?

[scottmd06]

I am working with a recipe that states 3 AAUs Willamette .66oz, 1.3 AAUs Fuggle .33oz, 2 AAUs Fuggle .5oz ...

How do I figure out how long the boil is for each hop? lol

a thorough recipe would show when during the boil to add each and how much. if it doesnt then you may have to wing it but the general layout i see most for a 60 min boil is 15 minute intervals and at 5 mins left usually evened out. if you post what type you are making someone may be able to tell you the timing more accurately.

It's a clone for Fat Tire, but I'm going to attempt it GF (gluten free), subbing the malts and grains for Sorghum Syrup, Brown Rice Syrup, and Molasses. The recipe I saw online for Fat Tire just had the info from above.. If anyone else has a more explanatory Hop schedule for a Fat Tire clone, it would be appreciated.
