The term chord is also applied to the width of wing flaps, ailerons and rudder on an aircraft. Many wings are not rectangular, so they have different chords at different positions. Usually, the chord length is greatest where the wing joins the aircraft's fuselage (called the root chord) and decreases along the wing toward the wing's tip (the ...
Radial (solid and colored lines) and circumferential roads (dashed and gray lines) in Metro Manila's road network. Axial – along the center of a round body, or the axis of rotation of a body; Radial – along a direction pointing along a radius from the center of an object, or perpendicular to a curved path.
x is the position along the chord from 0 to 1.00 (0 to 100%), y t {\displaystyle y_{t}} is the half thickness at a given value of x (centerline to surface), t is the maximum thickness as a fraction of the chord (so t gives the last two digits in the NACA 4-digit denomination divided by 100).
It assigns three numbers (known as coordinates) to every point in Euclidean space: radial distance r, polar angle θ , and azimuthal angle φ . The symbol ρ ( rho ) is often used instead of r . In geometry , a coordinate system is a system that uses one or more numbers , or coordinates , to uniquely determine the position of the points or ...
The wingbox continues beyond the visible wing roots and interfaces with the fuselage in the centre wingbox, which forms the structural core of an aircraft. The wingbox is so called since, on many designs, the combination of the forward and rear wing spars and the upper and lower wing skins together form a natural "box" shape running through the ...
The course line is selected by turning an "omni bearing selector" or "OBS" knob usually located in the lower left of the indicator. It then shows the number of degrees deviation between the aircraft's current position and the "radial" line emanating from the signal source at the given bearing. This can be used to find and follow the desired radial.

The leading edge is the part of the wing that first contacts the air; [1] [2] alternatively it is the foremost edge of an airfoil section. [3] The first is an aerodynamic definition, the second a structural one.
