Scope

This document discusses the relative merits of the physical and chemical properties of hydraulic fluids in relation to the aerospace hydraulic system design@ and the related materials compatibility. The discussion in this report applies both to hydrocarbon and phosphate ester based aircraft hydraulic fluids. In some cases@ numerical limits are suggested@ but@ in general@ the significance and effect of a property is noted qualitatively.
