Ist Tour Instructing
You have to remember that the military already have had quite a 'selection' process before anyone becomes a student,therefore the process then becomes one of super selection rather than more training.In a peacetime role when numbers required are low they can afford to be 'VERY SELECTIVE' and 'slow learners' will be lost on the way.Pilots should also have an ability to 'teach themselves' because apart from anything else they may well come across a situation that has never been covered in training.Handling skills will come with experience, but decision making is something a pilot has to develop quickly.
A first tour instructor also will remember the items that were important to him/her when training and that is quite important.In the civvy world where you have to train rather than chop because of the cost implications; instructors have to deal with a far more varied background of students so if the learning process is a little slower but 'gets there' the system works.
I think some basic flying training (power or gliding) is a valid input into good management skill training as it really sorts out the decision making in a very clear way.
