According to Rasmussen, three levels of behaviour with respect to the performance of tasks and problem-solving can be isolated, in which errors can occur. Rasmussen introduced the “SRK” model which consists of:

S = Skill-based behaviour
R = Rule-based behaviour
K = Knowledge-based behaviour

  • Skill-based behaviour.

This behaviour is shown when performing skills. It is based on practice and prior learning, to become part of motor programmes. Reactions are largely unconscious and automatic. As such, conscious control is usually not required. There are 2 types of pilot errors relating to skills, which typically do not occur in novices since they normally have to think about each action. Skill-based errors only occur in those with experience. Experienced personnel should keep in mind that they are prone to errors at this level when they are preoccupied, tired, or otherwise distracted.

Associated errors:

- Environmental Capture and Action slip => often known as Errors of Routine.
