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 departement-
specific• 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
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)

Next Step: Industry Benchmark
• Sharing experience with safety perfomance indicators and safety targets within the ACI community
• Unique (Zurich Airport Ltd.) would like to send you a short questionnaire• Your experience/views on this subject
• Comments on the proposed airport safety performance indicators
• Ideas comments regarding safety targets
• Any other comment
• WEB-Based questionnaire (need to perform login)
• Feedback of findings will be presented at the next ACI OSSC meeting or as required
