This SAE Aerospace Recommended Practice (ARP) is intended to recommend: a. uniform criteria for determination of wind loads that aircraft ground support equipment can encounter and yet allow personnel to work safely, b. uniform systems for maintaining stability (i.e., stabilizers, outriggers, spring lockout devices), c. standardization of specific types of interlock systems and actuation systems, d. a standard formula with its associated design criteria for calculating the steady-state wind stability (i.e., tip point) for aircraft ground support equipment, e. a standard method for testing these systems.
