Lubricating Characteristics and Typical Properties of Lubricants Used in Aviation Propulsion and Drive Systems
This SAE Aerospace Information Report (AIR) establishes guidance for the specification of formulated lubricant properties which contribute to the lubricating function in bearings, gears, clutches and seals of aviation propulsion and drive systems.
Rationale: Since issuance of AIR5433A, it was discovered that the pressure viscosity coefficient values for 3 and 4 cSt oils listed in Table 3 were in error. In addition, the specific heat units in Table 6 were incorrect. After review in the E-34C Lubricating Characteristics Subcommittee, these issues have been resolved in this revision.
