Good Day Bob / Richard / Lee,
Heaps of gratitude to you for the assistance in passing these two exams (AHUF and IREX)- very happy to be done with them!! I used the CHUF E-Text for the ATP Human Factors. And though I understand that you specialize in CPL, I found it to be of better quality than the other ATP "specific" stuff out there.
No matter how anyone tries to explain TEM though, it is just a slippery bugger for sure!
After much deliberation
I have come up with what I believe to be the most apt description of TEM, namely:
"The fine art of backing a fart into a corner using a pointy stick" 
For those preparing for the AHUF / CHUF, here is what I have found to be useful: The bulk of the exam is still based on non-TEM related issues, so make up for those vague TEM questions and answers by knowing the other material very very well!!
Don't use too many resources - it will just confuse you. Use CAAP 5.59, but DON'T get stuck into the
whole thing - only sect 13 and 14 are of any value - and even then it is only the examples that they use that adds value.
Other than the new Bob Tait E-text, my most valuable source was
www.skybrary.aero/index.php/TEM_in_Flight_Operations
Obviously some of this is said light heartedly. I DO believe that TEM
is important and should be promoted in aviation organisation and in training. I am just not of the opinion that it can be effectively tested in a typical multiple answer exam. At least not until CASA adopts a recognised bibliography that contains standard terminology / phraseology.
But hey, I've passed the subject and it is do-able.
Kind regards.
Andy
