Abstract

The measurement of displacements wherein the reference point, the point bg displaced, is not fixed are not easily accomplished. Collective control systems in helicopters are representative of such displacements. Precise rigging of the collective control system is necessary. This invention provides a displacement gauge which makes this rigging easier to effect.
