They do have some very good chaps working there if you look back over my posts.
Unfortunately they are let down with the training in the US on the fundementals of flying and also with the train for the test mentality in the IR.
The major issue I have is with the amount to be payed for what they give you. And the marketing rubbish which gets spouted forth.
And if its from them I suspect it will closely resemble the CFS navigation notes. If you trawl through BEagles posts on here, he has in the past taken the time to post some very detailed notes on the subject.
