Advisory Circular (AC) 150/5340-5D, Segmented Circle Airport

The segmented circle is the basic element of the system Segmentation of the circle is necessary so that from a reasonable distance it can be readily distinguished from a solid circle, which is sometimes used to mark the center of a landing area The segmented circle performs two functions; it aids the pilot in locating airports and it provides

TANGENTS, SECANTS, AND CHORDS

a flat surface Line a does not intersect the circle at all Line b intersects the circle in two points and is called a SECANT Line c intersects the circle in only one point and is called a TANGENT to the circle a b c TANGENT/RADIUS THEOREMS: 1 Any tangent of a circle is perpendicular to a radius of the circle at their point of intersection 2

AREA OF A SURFACE OF REVOLUTION

is rotated about an axis, it creates a simpler surface whose surface area approximates the actual surface area By taking a limit, we can determine the exact surface area The approximating surface, then, consists of a number of bands, each formed by rotat-ing a line segment about an axis To ﬁnd the surface area, each of these bands can be
