SMS is there to?
Define how the organisation is set up to manage risks
Identify workplace risks and implement suitable controls
Implement effective communication across all levels of the organisation
What is the sensory threshold?
Above the sensory threshold a stimuli is sensed
Bottom up processing
Sensed information is used to construct a perception. Eg touching a desk
Top down processing
A hypothesis is made and information is sought to back it up. This involves comparing information with past experience and knowledge. Eg building a mental picture of traffic over the radio
Once created mental models are?
Rigid and unsuceptible to change
Flichering lights jfrom strobes can induce.
Dizziness and vertigo
Perception is
Subjective
Vision, equilibrium, proprioception and hearing provide
Spacial orientation
Haze makes you think you are
Further away
Lack of texture can cause
False height perception
Up sloping runway makes you think you are
High
Therefore leads to too low of an approach and undershoot
Down sloping runway makes you think you are
Low
Therfore too steep and approach and overshoot
Narrow runway
Too high illusion
Shallow and undershoot
Wide runway
Too low illusion
Therefore too steep approach and overshoot
The leans
Turning in opposite direction after leveling or while leveling after a prolonged turn
Autokinesis is?
The perception that aircraft tend to jump from one place to another while flying at night
Black hole effect
Occus when there are few lights surrounding a runway and leads to a dangerously low visual approach
Coriolis illusion
False sense of tumbling when rapidly moving your head in IMC, exacerbating disorientation
Somatogyral
False sense of spinning
G related issusions are also called
Seat of the pants, avoided by trusting instruments
Enpty field myopia
Where you focus a few meters ahead therefore don’t spot other aircraft
An error chain is
Sequence of cumulative errors
Vigilance
Sustained attention
Selected attention
Select information from many factors and focus one that one source
Divided attention
Focusing on two or more stimuli at once also known as multi tasking
Hypovigilance
Low level of vigilance
3 types of memory store are
Sensory store, short term (working) and long term
Sensory store
Holds unprocessed information from the senses for brief periods
Short term (working) memory
Holds 5 +- 2 partially processed bit of information
Sensitive to interuption
Impruved by chunking
Think of remembering long ATC clearance
Long term memory is divided into
Semantic and episodic memory
Semantic memory
General knowledge of the world and language
Highly structured and organised
Never really lost
Episodic memory
Events or episodes or places we have been
For example fist solo
Amnesia is
Inability to re call or recognise events from episodic memory
4 types of learning
Classical conditioning, operant conditioning, insight (cognitive learving) and modelling
Classical learning is
Learning by association which is subconscious
Operant conditioning
Conscious change of behaviour
eg changing the way you flare
Insight (cognitive learning)
Drawing insights from pieces of knowledge and extrapolating from them
Eg a stall on final would be fatal without having to do it
Modelling
Imitating and reproducing behaviour
The 3 phases of aquiring a new skill are
CAA
Cognitive phase - consciously developing parts of a skill
Associative phase - linking component parts via practice and feebback
Autonomous - skill becomes automatic
Motor program is
A highly coordinated set of muscle actions
Mental schema
Recall and recognition
They reduce the amount of processing time required but can be difficult to change
Eg recognising exam questions
Rasmussen SRK model
Skill - smooth execution of highly practiced physical actions
Rule - actions based of rules which have been learned
Knowledge - construction of own response as a result of experience eg Sully
Under pressure pilots tend to result to
Revert to Rule mode of SRK which can result in poor task execution
Action slip
Intention was correct but there was a failure of execution
Error
Eg flaps instead of gear
Mistake
Incorrect intention
Error
Violation
Intentional deviation from what is knows to be the correct action
Can be routine (eg not doing checklists) or exceptional (eg in case of emergency)
Omission
Forgetting or missing an action or step
Fault
To do with hardware and systems
Active error
Short lived and have an immediate effect
Eg wrong frequency
Latent error
Errors which lay dorment
Eg cut back or lower quality pilot training
Environmental capure
Doing something because it is routine and familliar
Eg selecting flap when its a flapless landing
Decision making process is
D E C I D E
Define aim Explore options Consider risks Identify priorities Do it Evaluate
Risky shift
A more risky decision is make as a result of a group
Risk asessment factors
Identifying potential threats, probability of the threat occuring, consiquence of the threat
Co action
All crew members working towards same aim but not necessarily communicating
Synergy
1+1>2
Cohesion
How tightly knit a group is
Groupthink
Where the desire to reach a unanimous decision overrides rational decision making
Paternalistic
Discourages attempts by juniors
Status conscious
Ideal pilot leadership style
Balance between task orientation and people orientation
P+ G+

75%
Explicit communication
Clear intentions

- Difference of opinion
- Confrontation
- Flight or flight
- Combat
Personality results from
Genes and upbringing
Attitude
Behaviours in respect to things and situations
Behaviour
A result of personality and attitude
Ideal pilot personality is
Stable extrovert
Hans Eysenck model
If an underconfident FO…
Gets promoted to captain they can be aggressive if challenged
Hazardous attitudes
Invulnerable - can’t happen to me Machno - no one as good as me Impulsive Complacency Anti-authoritarian Resignation - give up, everything pointless Careless
Response to stress is
GAS - general adaptation syndrome
Yorkes Dodson curve
Inverted U is to do with stress and plots arousal and performance.
Peak performance at the peak of the U
Stress is a result of
Percieved demands and perceived ability
High levels of stress may result in
High levels of anxiety
3 phases of GAS
ARE
Alarm - brief initial shock which produces adrenaline
Resistance - lasts longest a releases cortisone, incleases blood flow
Exhaustion - fat reserves used up and drop in blood sugar level
3 reactions of stress
Physiological - restlessness, nervousness, anxiety
Psychosomatic - coronary heart desease, ulcers, permanently raised blood pressure
Somatic - alarm reaction
Stress coping strategies
Action - remove the stressor
Information seeking - understanding and predicting stress
Inhibition - deal with it/ suck it up
Pallitive coping - relaxation techniques
Obtaining support
Irony of automation
The more reliable the system, the less pilots have to do so the less attention they pay
TEM consists of
Threats - external
Errors - internal
Undesired aircraft states
Threats consist of
LEO
Latent - incorrect sop, published alt, same warning for different faults
Environmental - weather, high traffic
Organisational - culture, commercial oressures
Errors consist of
PAC
Procedural - reading wrong checklist
Aircraft handling - failure to maintain altitude
Communication - incorrectly hearing new frequency
SHELL components
