- Explain that:
Drug abuse is a behavioural problem and is independent of:
- dependence (addiction)
- frequent use.

- hearing loss: long/short term
- speech intelligibility
11.7 Vision, Disorientation, Illusion
Have knowledge of the anatomy of the eye and its function during the day and at night.
Know factors which affect night vision and identify methods of "dark adaptation".
Describe the limitations of the eye in discerning objects at night and the "off-centre" method of identifying objects at night.
Know the limitations of the eye with respect to
- The ability to discern objects during flight e.g.
- other aircraft, transmission lines etc
- myopia, hyperopia, astigmatism, presbyopia
Be aware of the importance of
- Seeking experienced professional advice for spectacles prescriptions
- Selecting suitable sunglasses
Know of the factors which are conductive to mid-air collisions and describe/practice techniques for visual "scanning".
Understand and define the term "disorientation".
Know the sensory systems involved in maintaining body equilibrium i.e. that
- equilibrium is normally maintained by use of the eyes, inner ear and proprioceptive system ("seat of pants")
Understand that these mechanisms were developed for use by land based mammals and do not provide reliable Learnrmation under all conditions of flight.
Describe illusion(s) that may be associated with the factors listed below
- Linear and angular accelerations
- Unperceived changes in the pitch; roll; yaw
- Autokinetic illusions
- "Graveyard spin" illusion
- Somatogravic illusion
- That sensory illusions usually occur when external visual clues are poor or ambiguous and that they are predictable
- The importance of an artificial visual reference system and a pilot's ability to use the system
- The factors that may make a person more susceptible to disorientation
- How to overcome sensory illusions.
Know what illusions may result from the following flight factors
- False horizontal clues e.g.
- sloping cloud formations and sloping terrain
- flying over water, snow, desert and other featureless terrain
- effect of fog: haze; dust
- approach angles: steep; shallow
- width and slope of runway
- slope of (approach)
- terrain approaches over water
11.8 Motion Sickness
11.9 Acceleration "g" Effects
11.10 Toxic Hazards
11.11 The Atmosphere and Associated Problems
State the chemical composition of the atmosphere and recall the variation of temperature and pressure with altitude.
Have a basic concept of the circulatory and respiratory systems in terms of the distribution of oxygen and the excretion of carbon dioxide.
Describe what is meant by the partial pressure of oxygen.
- List the causes of hypoxia and recognise the symptoms of hypoxia particularly
- its effect on night vision
- the dangers of behavioural changes e.g. lack of self criticism, over-confidence and a false sense of security
11.13 Human Factor Considerations
Know the concepts of Learnrmation processing and decision making including:
- How sensory Learnrmation is used to form mental images
- The influence of the following factors on the decision making process
- personality traits e.g. introvert/extrovert
- pride, peer pressure, employer pressure
- the desire to get the task done
- anxiety, over-confidence, boredom, complacency
- types of memory - long/short term
