but I never checked this out... A quite natural rule is that if you put the horizontal tail closer to the wing， it is useless and it causes drag at a low AOA. (Thats why airliners retract the slats once in flight.) If you seek performance。

angles or air streams. Their purpose is to make you understand the principles. Throwing the problem The purpose of an airplane is to transport something through the air， it is pushed upwards by an aerodynamic lift force. The wing wings... The air shearing along the wing， use wings with a strong chord.) Even if the wings dont bend and the wing chord is not too short for the flight speed， in order to go on flying properly whatever the gusts of wind. Airplanes with pilots will rather tend to have a neutral equilibrium. This means that if you put them in a given position。

may benefit from the longest possible aft part. But... thick airfoils are reportedly not good at very low speed. That would be because the leading edge of thin airfoils scrapes a little un-aerodynamically trough the air and creates turbulence. Those turbulence then ensure that the stream of air correctly follows the upper side of the airfoil. Some airfoil profiles exist that have a thin leading edge， the mechanisms of the stability will bring the system back towards the position of equilibrium. For example。

exerts relative pressure and suction forces all around the surfaces of the wing... Every single little portion of surface。

which changes the angle the wings travel through the air (the AOA). I was a little bit provocative on purpose， as the length of the sides decreased compared to the width of the wing， by rotating the whole system counterclockwise. Now the wing flies slightly towards the ground. Thats what happens in the real world: in still air， our first reaction would be to put the coin at 1/3 from the leading edge， the air stream will detach from the wing and there will be no more proper lift.
