1

Frequency of accidents

1 in 1.2 million flights

2

what percentage of accidents are caused by human factors?

70-80%

3

which phase of flight is most dangerous?

intermediate and final approach followed by the landing and then take off

4

3 pilot competency skills?

skill
knowledge
atitude

5

8 core competencies are?

communication
aircraft flight path management- manual control
aircraft flight path management- automatic control
leadership and teamwork
problem solving and decision making
application of procedures
workload management
situational awareness

6

closed safety culture

blame given
reluctant to release info regarding accidents

7

open safety culture

no blame
open about mistakes so others learn
accidents reviewed

8

James reasons 5 things for a good culture?

informed culture
reporting culture
learning culture
flexible culture
just culture

9

SHELL model

software - non physical things
hardware - equipment
environment - inside and outside climate
liveware - human element
liveware

10

Liveware - liveware

human interaction
possible miscommunication
staff relationships

11

liveware - software

non physical
how charts, SOPs etc interpreted
mode error- not recognising in wrong mode

12

liveware- hardware

physical
how we interact with design of aircraft
position and design of levers standardised
things operating with natural senses

13

liveware - environment

inside and outside climate
eg. too hot or cold,traffic ,terrain
company putting you under stress for quick turn around etc or fatigue from rostering

14

Swiss cheese model

each slice a defence
each hole is a weakness or limitation(active or latent), multiple lead to a failure
using defences can prevent accident

15

Active failure

short lived
directly linked to accident
poor airmanship by crew

16

Latent failure

been dormant for some time
poor management
crew unaware of them

17

TEM

process of detecting and responding to threats and errors , with countermeasures to reduce or limit the consequences

18

threat

out of influence of flight crew
must be managed by crew
2 types: environmental & organisational
may also b latent threat

19

error

influenced by crew action or inaction
deviations from intentions and expectations
3 types: aircraft handling error, procedural error, communications error

20

undesired aircraft state

unable to avoid, trap or mitigate threats and errors
3 categories: aircraft handling, ground navigation, incorrect aircraft configuration

21

systemic based TEM countermeasures

systems in aircraft
warnings and alarms: TCAS, GPWS
SOPs

22

individual and team TEM countermeasures

planning and anticipating:
SOP brief
plans stated
work load assignment
contingency management

review countermeasures:
evaluation & modification of plan
enquiry
assertives

23

TEM management; 3 lines of defence?

avoid (primary) 70% of flight
trap
mitigate

24

safety management systems 4 components are?

safety and policy objectives
safety assurances
safety promotions
safety risk management
