I am a Human Factors tragic - I love it - but TEM is a load of !!!!.
It is clumsy and awkward in practice - its another cute theoretical model forced down the throats of the people at the coal face as it it is actually useful.
Once you have been using it for a while it gets easier BUT do you reckon the examiners at CASA have ever worked as a pilot?
...much less actually used TEM as an operational tool?
Tossers.
