We're going round and round saying the same things - and this is from folks who understand the situation. Maybe the first real test might be to see how well a trainee grasps the concept. Perhaps its time we heard from them?
I suspect that we might be getting away from the "KIS" principle that has served us all so well, ever since the Wright Bros flew at Kittyhawk.
I have always referred to a "Total Reaction" force in a climb, for example, but this is a completely different situation to S+L flight. It's quite easy to introduce that concept at that stage because the trainee already has a grasp of the fundamentals that apply in S+L. I'm just not sure it's such a good idea to introduce the TR force in S+L, but I'm happy to accept that others can make it work without bamboozling a trainee.
