It would probably be of great asistance to the instigator of this post if someone could find and post a series of simple explanatory vector diagrams. I seem to remember that such diagrams were used to great effect during "theory of flight " briefings when I was learning to fly.
Such a diagram would show, for example, how the resultant of the lift vector
(lift and thrust) would be balanced by the resultant of the weight vector (weight and drag) in a constant climb, etc., etc.
I am unable to recall where I have seen the diagrams published, but it could have been "Flight Briefing for Pilots" by Allan Bramson.
Does anyone know what I am talking about?
