Default RE: Wing Loading

Hey guys
Since I am a flyer of 1:1 scale aircraft I will try to analyse with simple words what is happening so all of the guys who are missing some points will be able to understand a broad subject like this.
The flight of a wing configuration is affected by a whole set of different parameters. One of them is the wing loading. Some other are Reynolds, static weight, centre of pressure (dynamic weight), angle of incidence, angle of attack, wing type, airfoil type etc. Different airfoils are giving different results the same happens with different wing types. Some of them are high lift; some others are more penetrating so they are faster. There is always the compromise of lift in order to give it back for speed. So either we have wings that in their envelope fly faster; or they create greater lift in compromise with speed. Both situations give to our airplane energy to fly. As pilots
we must understand that in subsonic flights we have to weight first of all our wings in a correct manner (to keep the dynamic center of pressure always in balance with the static point of pressure. The angle of incidence is another factor that affects flight. It must be always according to the envelope. The high lift devices (flaps, slats etc) are increasing the lift. So they give the wing the ability to fly in lower speeds. In order not to be tiring, I will go dirrectly to the point that is:
Wing loading by itself is one of the points that affect the flight if it is not with accordance with the envelope. To be more specific it will prove us the flaws of our building experteese and specific our lack of picking the right airfoil, or wing type, reynolds, or missing flaps, slats etc.
You see judging by using one of the criteria of flight which is wing loading our result will be incorrect. Otherwise the 1:1 Boeing 747 would not fly right because it has a bigger wing loading than a Cessna 150 Skycatcher.......
These are my 2 cents.
