is cited in approximately 70 - 80 % of aviation accidents

Less experienced pilots differ from experienced pilots in the following way:

According to Rasmussen's model, errors are of the following type(s) in skill-based behaviour:

routine errors

A pilot can be described as being proficient, when he/she:

has automated a large part of the necessary flight deck routine operations in order to free his/her cognitive resources

Concerning the relationship between performance and stress, which of the following statements is correct?

A moderate level of stress may improve performance.

What are the main effects of a lack of sleep on performance?

It increases fatigue, reduces concentration and increases the risk of sensory illusions

What is synergy in a crew ?

The coordinated action of all members towards a common objective, in which collective performance is proving to be more than the sum of the individual performances

What strategy should be put in place when faced with an anticipated period of stress?

A strategy of preparing decisions
