"Airmanship is the consistent use of good judgment and well-developed skills to accomplish flight objectives. This consistency is founded on a cornerstone of uncompromising flight discipline and is developed through systematic skill acquisition and proficiency. A high state of situational awareness completes the airmanship picture and is obtained through knowledge of one’s self, aircraft, environment, team and risk."
What does TEM as a philosophy bring to the above that isn't already there. Airmanship is not uniformly defined beyond the above definition that is true. Airmanship is how your culture and experience has taught you. That is how we used to learn of course. We learnt on the job or as an amateur from our club and close environment. That has been true in the training of doctors, lawyers, actors, artists, joiners and bricklayers as well as for pilots. Some how all this knowledge came together though. Wherever in the world you go so much is familiar with differences only in cultural detail. Cultures run deep and so does airmanship with it tendrils in everything which makes it hard to define.
What is TEM? I have never found a short simple definition that is different from that of airmanship. So FIC101 you have told us what you have left behind but can you tell us what you have now joined?.
