Abstract

A system and method for measuring, or otherwise determining pitch length adjustments to a pitch link (401a) coupled to a rotor blade (105a-e) in a rotorcraft (101) includes vertical track adjustment indicators (423a) machined onto an exterior of the tube of the pitch link (401a) and a vertical reference indicator (421a) machined onto an exterior of the upper or the lower rod of the pitch link (401a). A metric of a pitch length adjustment can be determined by tracking or counting how many track adjustment indicators (423a) pass the reference indicator (421a) while the tube of the pitch link (401a) is being turned in either direction for increasing or decreasing the pitch length. The track adjustment indicators (423a) can be relied upon to track one or a series of adjustments for tracking a rotor blade (105a-e) installed in a rotor assembly (103).
