And Owain, in all probability, will refer you to a read of the late Arvel Gentry's articles -
Gentry Sailing | Theory and Practice - as he has previously.
The problem with flying training is that we dumb down the stuff to suit what the new chum needs to get started ... you don't need to be a brain surgeon to fix up a minor cut on the finger. Unfortunately, the simplifications have become gospel over the years rather than being viewed as contributory discussion. The pilot doesn't need to be up to speed with the engineer's approach to things - rather, he/she needs to have an appreciation of the practical application to stick and rudder stuff.
An appreciation of circulation theory tells the story but one needs to keep it conceptual, lest we frighten off the new punters. The theory is nothing new - it started off a hundred years or more ago in the engineering world.
