Question 21

Any person suffers death or serious injury, or in which the aircraft receives substantial damage or the aircraft is missing or completely inaccessible

Answer 21

Aircraft Accident

Question 22

several ways to classify an accident

Answer 22

level of damage incurred, by the extent of injuries caused, or by the cost of the damage to the aircraft.

Question 23

means damage or failure which adversely affects the structural strength, performance, or flight characteristics of the aircraft, and which would normally require major repair or replacement of the affected component.

Aircraft Incident

Question 29

The difference between an accident and a serious incident lies only in the _________

Answer 29

result

Question 30

a short, sudden and unexpected event or occurrence that results in an unwanted and undesirable outcome ... and must directly or indirectly be the result of human activity rather than a natural event’.

Answer 30

Accident

Question 31

Three categories of accident causation models

Answer 31

Simple Linear Complex Linear Complex Non-Linear

Question 32

accidents are a culmination of a series of events or circumstances. There is a sequential interaction of events – one leads to the next one. Hence the belief that if the sequence is broken by removing one of the events, the disaster will be avoided

Answer 32

Simple Linear

Question 33

Presumes that accidents result from a combination of latent hazards and unsafe acts that continue to happen sequentially. The model considers a variety of factors, including environmental as well as organizational effects.

Answer 33

Complex Linear

Question 34

accidents are the results of a combination of mutually interacting variables occurring in real-world environments. Understanding these interactions through careful analysis is the only way to understand and prevent accidents—a systemic model that focuses on the system's interactions and functions rather than just individual events. Accidents are regarded as emergent rather than resultant phenomena (i.e., are not predictable).

Answer 34

Complex Non-Linear

Question 35

States that accidents result from a chain of sequential events, metaphorically like a line of dominoes falling over

Answer 35

Heinrich's Domino Theory
