When you look at a plane side-on. The left-most edge of the rudder attached to the fuselage is the leading edge whilst the right-most edge of the rudder is it's trailing edge.
The leading edge of a radar pulse determines range accuracy. The trailing edge, along with pulse width, determines minimum range.
The trailing edge is where the air flow comes together. The leading edge is where the air is diverted to produce the low pressure (top) and high pressure (bottom) to create lift.
Trailing edge is the rear edge of a wing.
100 feet
Gliders circle by turning. This needs a down aileron on trailing edge of the outside wing, and up aileron on the trailing edge of the inside wing, and a little inwards rudder to balance the different drag from each wing, and a little down elevator from the horizontal tail trailing edge to keep up the speed even though the drag has increased. So when a glider flies in circles, it descends, unless there is an updraft.
The kind that goes fast.
wingspan is defined as the distance from wing tip to wing tip
Internal stress exceeds the strength of the material. The cause of the stress is that the "leading edge" of the object stops while the "trailing edge" is still moving.
Airplane engines are affixed to the front fuselage (nose), the leading or trailing edge of the wings, or the tailplane, depending on the type of airplane.
Trailing edge
Chord refers to the distance from the leading edge of a wing to the trailing edge of a wing. Because wings are not perfectly rectangular, average chord is used and is calculated by dividing wing area by wingspan.
Air doesn't. Suction does. If you were to measure the wing from leading edge to trailing edge along both top and bottom surfaces, you'll find the wind has a longer distance to travel along the top than the bottom. This makes the air pressure lower above the wing than below it, and the lower air pressure pulls the plane up.
