The term “aircraft cable” is a generic term used to denote wire ropes from sizes roughly .047” to .375” and constructions 7x7 and 7x19. Class 7 x 7 denotes a cable constructed of 7 strands with 7 wires per strand. Class 7 x 19 denotes a cable constructed of 7 strands of 19 wires per strand. The greater number of wires per strand in a cable of a given diameter, the more flexibility it has.
