Also known as scallop. (navigation) Cyclical variations in the apparent guidance path generated by a four-course radio range or instrument landing system, at speeds greater than can be followed by the vehicle. scallopingA VOR (very high frequency omnidirectional radio-range) bearing error caused by the distortion of propagation over uneven terrain. It is often evidenced by a rhythmic swaying of the left or right VOR needle. Also called the bends.scalloping
scal·lop·ing (skal'ŏp-ing), A series of indentations or erosions on a normally smooth margin of a structure.Gastroenterology A descriptive term for the appearance of Candida oesophagitis, where there are irregular serrations, seen by a barium swallow
