TERM DEFINITION Select The flightcrew action of requesting functionality or an end state condition.
Significant Transient See “Transient.”
Stability Augmentation System Automatic systems that provide or enhance stability for specific aerodynamic characteristics of an airplane (for example, yaw damper, longitudinal stability augmentation system, Mach trim).
System A combination of components, parts, and elements that are inter-connected to perform one or more specific functions.
Transient A disturbance in the control or flight path of the airplane that is not consistent with response to flightcrew inputs or environmental conditions.
Minor Transient: A transient that would not significantly reduce safety margins and which involves flightcrew actions that are well within their capabilities involving a slight increase in flightcrew workload or some physical discomfort to passengers or cabin crew.
Significant Transient: A transient that would lead to a significant reduction in safety margins, an increase in flightcrew workload, discomfort to the flightcrew, or physical distress to passengers or cabin crew, possibly including non-fatal injuries.
Note: The flightcrew should be able to respond to any significant transient without:
Exceptional piloting skill, alertness, or strength, Forces greater than those given in § 25.143(d), and Accelerations or attitudes in the airplane that might result in further hazard to secured or non-secured occupants.
Warning A flight deck indication that alerts the flightcrew to a nonnormal operational or airplane system requiring immediate recognition. Immediate corrective or compensatory action by the flightcrew is required.
