Why measuring Safety Performance?
•
•
•
•
•
•
observe performance of operations
identify and analyse undesirable trends in service
establish basis to define safety targets
define effective means to achieve an acceptable level of safety
initiated corrective actions in an efficient and effective way
Compare safety perfomance with identified hazards
And…

Requirements and Challenges
Requirements 
• Easy to measure
• Company or departementspecific
• Lagging and leading
• Credible and accepted by staff
• causally related to accident and
incident frequency and severity.
• include system failures as well
as human error.
• include the whole spectrum of
airside operations
4 l
l ACI OSSC Amsterdam, 11.-13.9.2007
To be avoided 
• Inconsistent definitions
• Focus only on very few
indicators
• only reactive, lagging indicators
(e.g. accidents, accident rates)
• complex and impracticable
• Based on incomplete or false
data
• Benchmarking may result in a
distorted picture (different
reporting thresholds)
