I can highly reccommend using the Nathan Higgins AFT stuff. I have used all his notes on the distance course and then upgraded to the full time course when i could manage to get the leave off work to knock off Aerody and Sys, Flight Planning, Perf and Loading, and Nav.
I am about to have my ATPL Nav exam on tuesday morning which will then be my last subject, having just completed the Higgins course, and it was excellent. The explanations are simple and easy to understand and follow. The support through phone calls and emails is also a big help. The practice exam questions like all his other subjects include worked answers which are explained why it is done the way it is.
Highly recommended.
