5.2.2.4 Decision Making and CRM
Therefore, when faced with an abnormal situation, you should, depend on your good judgment and your CRM skills, gather information from various sources first, before making a decision. This is especially true when you have to decide whether to press on, turn back or divert. Do not rely on the one-man-operation instinct. More heads are usually better than one. Ultimately your decision is to make a safe landing and save lives.

5.3.1 Behaviour Patterns & Pilot Error
When human beings and other mammals are subjected to a life threatening situation, their usual reaction will either be “fight” or “flight” from the situation. The instinctive build-in defensive reaction will either save their skins or lead them to fatal mistakes.
Good judgment plus situational awareness lead to good decision making, the outcome will be averting the situation and saving one’s skin. But bad judgment and the lack of situational awareness leads to bad decision making and finally culminating in making mistakes that lead to incident, accident or disaster !
Human behaviours can perhaps be classified into various operational definitions as many aviation psychologists do. Operational definitions of the concepts are provided below in alphabetical order. The operational definitions were derived from James Reason’s works and other sources.
5.3.2 Automatic Behaviour :
A rote action performed without awareness or intent. Although automatic behaviour allows a person to accomplish a task while thinking about something else, automatic behaviour can lead to inattention and error. When a skill is highly learned – perhaps because it has been practiced for years – the skill becomes automated and requires minimal conscious awareness and minimal application of mental effort.
