Added bullet for unmanned aircraft systems: “For unmanned aircraft events, includes hazardous outcomes involving deviation from intended flightpath associated with anticipated or unanticipated loss of datalink. However, if loss of datalink is the direct result of a system/component failure or malfunction, code the occurrence as system/component failure or malfunction – non powerplant (SCF-NP) only.”
