Radial

Forms radiating from or converging to a common center or developing symmetrically about a central point.

[′rād·ē·əl]
(graphic arts)
A line or direction from the center (principal point, isocenter, nadir point, or substitute center) to any point on a photograph.
(mathematics)
For a plane curve C, the locus of end points of lines, drawn from a fixed point, that are equal and parallel to the radius of curvature of C.
(navigation)
One of a number of radial lines of position defined by an azimuthal radio navigation facility and identified in terms of the bearing (usually magnetic) of all points on that line from the facility.
(science and technology)
Directed or diverging from a center.

radial
In the above figure, reporting point Akola on B29 is defined by VOR radial. 020 R means it is on 020° radial from the VOR.
radial
Single row radial engine.
i. A discrete bearing, usually magnetic, transmitted by a navigational beam (very high frequency omnidirectional radio-range, or VOR; tactical air navigation, or TACAN; very high frequency omnidirectional range tactical air navigation, or VORTAC; etc.), which is the origin. There are 360 radials radiating out from any navigational aid (NAVAID), and each radial is named for the number of degrees clock-wise from magnetic north that the radial leaves the navigational facility.
ii. A reciprocating engine in which cylinders are arranged radially or like spokes in a wheel.
iii. A line or direction from the radial center to any point on a photograph. The radial center is assumed to be the principal point, unless other-wise designated; (e.g., nadir radial).
