USE OF GLIDING
One of the facets of ATC GLIDING (in the days of minimum dual and max solo's) was it encompassed so much for youth to adhere to.
It had a good balance of discipline against enthusiasm, and promoted decision making at an early stage. It needed confidence with capability, and also bought out what we would now call networking with Cadets helping other Cadets to master the system.
There are no negative issues with regard to learning some good basic aviation ways, and the system was flexible enough to not get overburdened with the now ruinous box ticking of today.
Had we merely stopped using open cockpit fretwork fighters and gone to a medium performance metal or glass machine in a simple change then we would still be doing the same job with perhaps a couple of extra dual launches, and a simple flight guide that the Cadets could refer to prior to attending a school.
Even the RAF were surprised how students on the 'all jet courses' coped so well despite the comprehensive 'check lists' that had to be learnt.
If you are not told something is difficult its amazing how people cope.
