Inform of the relative motion & relative position of body parts.
When does knowledge based bahaviour occur?
When rules can no longer be applied to a situation.
Why should pilots not fly immediately after giving blood?
There is a risk of lowered blood pressure.
What are the main strategies for adapting to time constraints?
Planning ahead and prioritising
What does acute fatigue usually result from?
Short term physical effects
When is reversion to previous behaviour patterns most likely to occur?
During high stress or very relaxed situations
To what levels of stress does the body adapt to repeated exposure of?
Moderate
What should an aircraft system be able to do regarding pilot interaction and avoiding errors?
Tell the pilot of a system malfunction.

Aggressiveness

At any time.
If an individual does not want to fly but is going to, what kind of symptoms may occur?
Air sickness and lack of sleep.
What defines an informed culture?
One that collects and analyses data and disseminates safety information.
What defines a reporting culture?
One that cultivates an atmosphere where people have the confidence to report safety concerns without blame.
What defines a learning culture?
One that is able to learn from mistakes and and make changes.
What defines a just culture?
One where errors or unsafe acts will not be punished if unintentional.
What are the most critical perceptual illusions?
Visual, Kinaesthtetic and auditory.
